Dual-channel RAM -- more in channel 1 or 2? Does it matter?

Q: Dual-channel RAM -- more in channel 1 or 2? Does it matter?

Hello,

i understand how to set up dual channels with matching pairs - that is not my question. What i can't find the answer for is this:

If i have a matching pair of 512 = 1g
and a matching pair of 1g = 2g,..

Does it make a difference which pair is in which channel? Should i have 2g in channel 1 and 1g in channel 2, or would this make no difference?

thank you!!

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

A: Dual-channel RAM -- more in channel 1 or 2? Does it matter?

You can run different stick of RAM at the same time in Dual channel asynchronous, but I think they'll operate at single channel speeds.
If you decide to run in asynchronous mode, I think that it doesn't matter.

Here's the problem, I'm building my new PC as we speak and I bought this mammoth cpu cooler (which while I knew it would be big I didn't read any reviews stating it covers a memory slot) which fully covers up my first ram slot and the heat spreader is too tall on the memory to try and weasel it in there. The Gigabyte's instructions tell me that there are two "dual channels" one using 1 and 3 and the other using 2 and 4. I installed the RAM into 2 and 4 because there is no other way for it to work. Is there any reason I wouldn't get the same performance out of slots 2 and 4 as opposed to 1 and 3?

i believe my mobo only accepts single channel memory, i tried to upgrade my system with dual channel, and it reboots constantly. please advice!!!!!
 

A:single or dual channel memory does it matter?

There is no such thing.....

The memory DIMMs are neither single or dual channel, it's the motherboard that determines how the RAM is accessed. Did you match exactly the specifications of the original RAM when you upgraded?
Please follow this link to Tedster's guide for upgrading RAM: http://www.techspot.com/vb/topic47210.html

When RAM is sold as "dual channel" it simply means that there are two DIMMS (each with half the amount of the upgrade value), one for each channel of a dual channel motherboard.

Hey everyone I got a bit of a problem here and I'm at a loss on what to do to fix it Some background about the situation would be a good place to start A few days ago I came home from work and found my PC in a quot lights are on but no one's home quot state The power button was lit up and the fans were in motion but the monitors were in power saver mode not the normal on state with the blank screen saver I tried moving the mouse mashing on the keyboard but nothing happened So I reset the machine and it just went to a blank screen no beeps or messages just the same ole lights on no Stopped Suddenly Single Working, Remains Only Dual Channel Channel ones home deal again Now before this I had been having memory problems with blue screens saying quot memory management quot and quot IRQL not less than or equal quot So I thought it might be a bad strip of ram and even bought two Dual Channel Suddenly Stopped Working, Only Single Channel Remains more strips to replace the ones I had removed In the process of testing each strip I discovered that one was bad That was not the fix by the way After putting in the new ram in for a total of GB's of ram figured if I'm gonna buy new ram might as well increase the total amount it booted up and no more blue screens after loading into windows YaY it was fixed or so I thought Dual Channel Suddenly Stopped Working, Only Single Channel Remains A few weeks later the above incident occurred and the only way to get the PC to boot up was to pull two strips of the ram and insert the remaining strips into slots and for a single channel configuration Didn't matter which set of ram I used just so long as I didn't mix two different brands on the same channel It's never needed to be set in that manner before CPUID reports it as single channel with a blank entry in the DC mode so I assume its ganged up and in single channel YUCK While the PC is operational since I'm typing this up on it I know its not at its optimal configuration which annoys me to no end After researching the problem via Google and numerous forum post with info unrelated to my exact problem I decided to write up a post in the hopes that some one out there can help me to figure out if the problem lies in my motherboard doubtful or in the processors integrated memory controller I think its the Phenom's memory controller that is faulty or failing It's been in operation since almost continuously and its been a good computer and still is I think the new ram might have been the culprit that shot my memory controller in the back There CAS RAS ratio's do not match by one number one is at CAS the other set CAS and when all GB's was installed the ram would run at not the mhz it's rated to run So like a dumb ass not knowing enough I went in the BIOS and overrode the auto setting for the ram and set it mhz vs the mhz it was defaulting to Did I inadvertently over work the memory controller All the current Ram I have is working and not faulty So that only leaves the Mobo and the processor I don't have tons of cash to spend I'm a poor man So before I bite the bullet and buy a new Phenom to replace the one I have I'd like to try and verify if that is indeed the problem System Info Asus M A -M Motherboard AMD Phenom II X B E Ghz unlocked and over clocked it once but it was unstable back in NVIDIA GT GB mhz Core mhz Bit Width Bit to GB's of Ram when it worked it was at GB's now it's at GB for now SATA Hard drives all independent of each other not raided W OCZ PSU I think that's the gist of the system info one would need If it is indeed my processors memory controller and there is nothing that can be done with what i have on hand to correct the problem then I plan on buying a Phenom II X It's about the same price as my X was in Plus it has the same socket and should work with my motherboard Could the motherboard some how be at fault how can I test this without additional hardware Here is more information about my memory Sorry I didn't post enough information he...

Britton, go to the asus site for your motherboard. Download and install the latest drivers. Download a copy of your manual and review the bios settings. If need be manually input the correct timings for your ram. Also make sure to follow the ram installation documentation for which slots to use to enable dual channel.

My spec is in my profile, but I will also list it here.... I just noticed today that my RAM was running Single Channel mode, so I thought I would change it to Dual Channel mode... so I did.

It completes the Windows XP loading screen, then reboots... constantly, until I change it back to Single Channel mode.

Is there something wrong with my RAM? or is it the motherboard? or my PSU not giving the mobo enough power? I dont have every power cable plugged in, I have a 20 pin ATX power in the 24 pin plug, and the 4 pin ATX power plug and a 4 pin molex cable plugged into the motherboard. Could this not be giving it enough power?

A:System reboots constantly, when I change my RAM from Single Channel to Dual Channel

Check your mobo manual, to see in which slots you need to put memory sticks to make it work in Dual Channel mode.
AFAIK you need 1 each of the same size/type in slots 1 and 3 (yellow) for DC.

Hi, I currently have 2x2GB Corsair DDR3 1333MHz RAM which I had bought around 3 years ago. I am currently thinking of upgrading to 8GB. However, my vendor tells me that 2GB sticks are no longer available for Corsair and that I have to either get a 4GB or 8GB stick.

My current 2x2GB runs in dual-channel mode. If I buy an additional 4GB stick, it will run in single-channel. I use the desktop mainly for gaming purposes. So, I just need to know if mixing 2 modes will cause any problems?

A:Any drawbacks to mixing single-channel and dual-channel for RAM?

Shouldn't cause any problems assuming it is otherwise compatible.

The difference between single and dual channel is minimal for most usage scenarios. If the RAM you have now magically went to single channel 5 minutes from now, you likely wouldn't notice.

You could discard the 2 x 2 you have now and replace with 2 x 4 and get dual channel, but nothing at all wrong with instead spending that money on cigareets, whiskey, and wild, wild women. At least you'd have something to show for it.

They would work in a single channel motherboard, and it wouldn't effect the speed of the actual RAM however it would effect the overall speed because the memory wouldn't be able to send data back and forth as fast as it could in Dual-channel motherboards.

Hi.. So as usual im an idiot and i looked into my case and am still debating if my ram really should sit right next to eachother and i started Speccy and it said that i had single channel ram 2 different channels with 16GB total. I got confused becouse the motherboard manual said i should put the ram like i did.. So now i moved one ramstick, Whent into bios to check if everything was working like it should and now i have dual channel 16GB ram 8x2.
This started a question.. What performance boosts does dualchannel give over single channel.. I know its better but just. In what cases will it be "better" and will you notice it? And in witch scenario will you notice it?

A:Single channel VS Dual Channel RAM performance boost?

almost all mother boards that have 4 ram slots have colour coding. the 2 the same colour, normally a space in between is the dual channel setup.

dual channel effectively doubles the memory bandwidth and halves the cache.

in real world terms youll get a 5-20% performance increase with dual channel when running bench marks.. you probably wont notice it in terms of speedyness though.

A:Dual Channel memory in single channel board?

Well, I can say I solved my own problem.

After I spent the last 4 hours trying to find the problem. I ran a bunch of mem tests, cleaned the mem slots, etc... It turns out it wasn't a hardware issue at all. I was wiggling my mouse on start up and noted the time it froze... and every time it froze an application was launching in the system tray.

Turns out it was Norton F'ing Anti Virus....

The second it launched the computer froze. So I booted in safe mode and disabled the start up and all other functions of Norton. Rebooted in normal mode, and sure enough, it worked! Without a hitch!

Now here comes the Beach of it. Since I couldn't uninstall Norton because I disabled it (i.e. nothing would run because all the extensions, shells and services for it were dead), I rebooted in safe mode to uninstall, BUT Norton doesn't work in safe mode... WHAT!? The damn program specifically states in a condescending dialog box that you "must reboot in normal mode to access Norton... blah blah blah"

What kind of Virus program doesn't let you access it in safe mode? Isn't that the point, to run a virus scan in safe mode? Piece of crap! But anyways, I digress.

So now I finagled a way to run in normal mode without Norton launching to uninstall it. Uninstalling as we speak, actually.

*SO*

To answer my own question:
Yes, dual channel kits work in single channel boards (Just make sure you uninstall Norton before you put the new RAM in, haha).

Hi guys,

If I replace the two 512mb sticks am I better off getting a matched pair of sticks for dual channel. A matched pair in most stores seems to be more expensive than just buying two sticks of the same type. What is the difference? My motherboard does support dual by the way.
I think when I bought the two 1GB sticks I just bought 2 of the same make in pc world, but not a matching pair.
I would like to know, does it really matter?

My current computer, which I bought late 2004, came with 512MB dual-channel RAM. Because of the 70 updates to Win XP that have occurred since then, with their attendant security crap that burdens the system, I decided today to double my RAM to 1GB. I did that by buying a single 512MB PC 3200 DIMM.

However, my PC has 2 pairs of memory slots. The original 512MB were installed as two 256MB DIMMs, one in one slot in each pair of slots so it was accessed as "dual-channel" RAM. My ASUS MoBo book says that if you insert a SINGLE DIMM in any slot, the entire memory will be addressed as single-channel. So my question is, what's the difference in speed between dual- and single-channel memory? Am I cheating my computer out of higher memory speed by installing a single 512MB DIMM vs. using two 256MB DIMMs which would run as dual-channel memory?

A:Mixing Dual Channel and Single Channel Ram Help!

:wave: Hello & Welcome to TechSpot :wave:

No, dual channel has (next to) nothing to do with the ram chips, but how the motherboard accesses the ram.

The reason you se Dual Channel RAM packages are that those are matched pairs (from the same production batch), and are supposed to give better results than two identical ram sticks bought separatly....

Also, buying dual channel sticks won't do anything for you if your motherboard/cpu doesn't support it. But you don't have to worry about that with your current mobo.

Actually, your mobo has a very good and detailed manual, which tells you how to use dual channel ram stick on page 19.
It even has support for using 4 sticks of ram, unlike many other (older) mobos.

So read that page, and if you still have questions, come back here.
If you can't find your manual, you can download it from here..

Hi, can anyone tell me if there could be a benefit buying 4 x 1 GB DDR2-800 DIMMs, as opposed to 2 x 2 GB DDR2-800 DIMMs? I know the difference between single channel and dual channel is pretty huge, but I'm not sure if it would matter going to quad from dual. I haven't found anything that really helps on the internet.

The reason I am asking is because 4 x 1GB DIMMS are about 25% cheaper than 2 x 2GB DIMMS, however for future upgrade purposes I will have to get rid of DIMMS with the 1 GB sticks, where with the 2 x 2GB I wouldn't. I think the differences between saving now and saving later when upgrading is negligible...so if there is a noticeable performance difference that would help choose.

I just bought a Dell Studio XPS with an Intel Core i7 chip and fell into the trap of buying 8GB of DDR3 SDRAM (config 2x2GB/4x1GB), which has to be dual channel. My understanding (now) is tri channel is a better way to go. Dell will not refund or exchange sticks.

Dell tells me that the mother board will support tri channel. Can I convert to 6GB tri channel simply by pulling out 2 1GB sticks and creating a 2, 2, 1+1 config, or would it have to be 3 2GB sticks. In the same way, could I buy another 1GB stick from Dell and create 9GB tri channel using a 2+1, 2+1, 1+1+1 config (or does it have to be 3 3GB sticks)?

How does 8GB dual channel compare with 6GB or 9GB tri channel memory?

Are tri channel memory sticks inherently different from dual channel sticks?

recently it came to my notice that i was running my RAM on single channel mode (2x2gb) on my dh67bl mobo. i saw it in cpu z and it showed single channel.

So, i changed my ram and placed it in identical slots and now the Cpu z shows dual channel RAM. but i don't see any visible difference in performance.

Why is it so? is there any performance difference in running the RAM in dual channel / single channel?

kindly advice,

A:RAM: Single Channel to Dual Channel.....no difference?

Hi Ray,

By placing your RAM into dual channel mode, you have effectively doubled its bandwidth, meaning that twice as much data can be transferred at a given point in time.

There should, in theory, be a noticeable difference between single and dual channel mode. However, this depends on the application. For many programs, such as Office (Word, Excel, etc), there will be a slight difference but not as much as you will see with graphics editing or movie conversion.

What is your current WEI score for the memory component? Rerun the assessment and you should see an improvement in this value.

There's no such thing as dual channel memory,if the two sticks you've got now are exactly the same,then you can probably run them in dual channel.It depends on which slots you use,it's either 1&2 or 1&3.Check your manual to see,or post your motherboard make and model.Also,is there any reason why you want 4gb of memory.

It will recognize it but not run in dual channel if the pair are mismatched.
Ps; The pair don't have to be exact matches by the way, same speed, type, size, and timings allow for two different brands to run in dual channel.

Hello forum first time here. I have a rather important question.

I currently have Corsair Vengeance memory in my PC

This memory is Triple Channel

I also have 8GB of GsKill dual channel memory. Since i have 1 extra slot left on my Mobo i was gonna use 1 of my old GsKill sticks to give my PC 14GB of ram. There identical except brand and dual / triple channel. Does Dual / Triple channel prevent these from working together?

Thanks in advance.

Heya, I'm new here, recently, my friend said I had a computer that could have a "dual DDR channel"? I dont know much about computers, and i wanted to know more, so he checked my computer with a program thats called "Cpu-Z" and it said my DDR channel was Single, even though all my "RAM" slots are filled with DDR 512mbs, any reasons why?
 

A:Switching from Single DDR channel to Dual DDR channel?

Well there may be a setting in Bios to set it for dual channel
Or even a little jumper on the Motherboard that must be placed on the correct pins

You will need to download your computer's (or motherboard's if it's not a name brand) Manual

Well, as it says in the title:
Is single channel 1gb as good as dual channel 2*512 mb.

I have tried to add memory to my mobo, but something went wrong and now my mobo only sees the first memory module. Really, I've tried everything and now I give up to return to normal life until I buy a new system.

So at first I had 2 * 512 mb memory at 800 mhz, dual channel.
Now I have 1* 1g memory at again 800 mhz, but single channel.

So is that ok, or is running at single channel much inferior to dual channel, even if I have the same amount of memory?
 

A:single channel 1gb as good as dual channel 2*512 mb?

No. Single channel is NEVER better than dual channel. Dual channel is always better and runs faster.

A:i7 - Triple Channel VS. Dual Channel

Well it seems that you are upping the CPU from 2.66 to 2.8 this would probably balence out the tripple down to dual channel performance loss if not beat it. But then you are going from 6gb to only 4gb of RAM so that would probably lower performance on some really demanding programs or some seriously intense multi-tasking.

Hello All, i was wondering what is single channel and dual channel. This question came to my mind when i ran my PC with single RAM stick it shows "running on single channel" and when i inserted the second stick it says "running on dual channel". What is this?.......Also my graphic card crashes when i use the second stick, but runs smooth with single. I ran a memtest throughout night and got a blue screen in the morning. I will replace my RAM if it is faulty, but would like to know if there is some settings missing on my mobo.

A:Dual channel vs Single channel

Essentially, dual channel means that you have two channels/pathways for your CPU to access your RAM rather than one in single channel. It's kinda like having a 2 lane highway versus a 1 lane highway to drive on. Think increased space for data flow. More space, more data. It improves performance.

hi!
its about my old desktop computer..
abit nf-m2s motherboard, amd athelon 2.4Ghz prossesor, 2X512MB RAM(!!!).
i have installed windows 7 (32bit) on it a month ago, but after getting pissed of waiting i decided to buy another 2Gb ram, and replaced it instead of one of the 512-ram (bad move i guess) and at the beggining it seems to work fast and well (computer properties showed me 2.5gb ram).
after an hour of using it stuck, when i restart the computer, while noticing that on the startup it says 'single channel-64 bit' (and not 128, i guess). .. and stuck again..
i tried working only with the 2gb card, or back only with the 2X512 - nothing helps.

is there any solution besides reinstall win 7 with the 2GB card?
does another 2BG card for faster duel channel will be helpful(with my slow processor..)?

waiting for salvation..

A:dual channel to single channel

Usually, to get dual channel, you have to install RAM in pairs of the same size.

If you are using multiple pairs, the pairs don't have to be the same size. (Example: two 1GB DIMMs, plus two 2GB ones, would support dual channel, although they'd have to be in the correct slots.)

I belive that some motherboards can use dual channel mode with 3 DIMMs, but it's not obvious how that works.

My Intel X58 motherboard claims to be able to do triple channel with 4 DIMMs in the right slots, but I've never tried it.

I've been running Kingston HyperX 240-Pin DDR2 675 (PC2 5400) Dual Channel SDRAM for over a year now. I just realised that it is only running in Single Channel mode. I'm pretty sure it's because my mobo Foxconn 915A01-P-8EKRS only supports Dual Channel with a bandwith of up to 533 (PC2 4200). My question is, if I purchase the 533 version will I be able to run the new pair with Dual Channel while running the old pair with Single Channel?

(I know that the old pair will probably jump down to 533 also.)

Also, do you think it would be worth it for $100? Is there a noticeable difference?

Hey Tortured,
to the public at large Intels Tri channel memory bandwidth goes unused as not a whole lot takes advantage of it, and most users would not realize a tangible difference. Doing graphic design is one of the exceptions though, and you would probably see a substantial gain from it.

I have the X-Fi SupremeFX PCIe card that comes with the Asus Rampage II Extreme. Its hooked up via Digital Coaxial to a 5.1 HTS Receiver.

I don't have any issues with 5.1ch Dolby Digital when watching DVDs that support it. But all my other audio only comes out the 2 front channels as PCM. On my older computer with a Sound Blaster Audigy card, I was able to get 5 channel stereo through PCM by hooking up through the digital out mini jack and out again through a Digital coaxial cable into the Receiver.

Is there any way to be able to send the 2ch audio to the surround speakers using the SupremeFX card cabled directly to my receiver?

Thanks for any input.
 

A:Faking a 5 channel signal with 2 channel audio?

Dolby Pro logic supposedly responds to the directionality of a signal, and that's how it synthesizes(or perhaps extracts) the 5 channel info. Well that's great, but I have found that it sounds like s*** on a 2 channel music source, So, I just use the surround modes and allow myself to be entertained with rear channel surround. If the front channel speakers are imaging correctly, there is no need whatsoever for a center channel with music.

Plan "B" is obviously a brand new receiver with discreet 5 or 7 channel inputs. And that pins you to 1 specific listening position, or the effect is lost.

A:Quad channel RAM in triple channel mobo?

The short answer is yes. There is no such thing as quad channel ram, or triple or double for that matter. Ram is ram and you run it in single, dual,triple mode that is determined by the memory controller and the motherboard architecture. ram kits are bundled as "dual channel, or "triple channel" meaning that they are ostensibly tested and certified to work together in tandem. usually it means that they were manufactured in the same lot and taken from the line in succession. You can use a portion of a triple channel kit for your dual channel setup, or parts of two dual channel if you like. The only caveat to this is tat the 4 GB modules seem to get a little more finicky than do the 2 GB mods. In all likelihood they will work just fine. But you might want to consider shelling out the extra for a certified set.
hope that helped.

Hi, What is Dual Channel Ram? When they dual channel 1GB, is it basically combining 2X512mb DDR? Or is dual channel actaully something else, like faster?
Any help would be aprrecieated
 

A:What is Dual Channel ram?

Dual channel means that your motherboard can read from two memory sticks at the same time, thereby effectively doubling the memory bandwith.

Ideally, the two memory sticks should be as closely matched as possible. Some memory makers sell matched pairs of memory sticks and call it dual channel RAM. The memory itself is just regular old SDRAM. As you stated, 1 GB of dual channel RAM would consist of two 512 MB sticks.

Note that buying dual channel RAM does not give you dual channel performance if your MB is not so equipped.

Could someone explain what Dual Channel DDR is and how much faster is a computer with dual channel RAM to one with standard RAM?
 

A:Dual Channel DDR

I'm guessing you know how RAM works, Dual Channel, is far better than Single channel mode mainly because it effectively doubles the memory bandwidth you have.

i.e.

Assuming you know :-

266MHz = PC2100 or 2.1GB/s Peak theoretical Bandwidth
333MHz = PC2700 or 2.7GB/s Peak theoretical Bandwidth
400MHz = PC3200 or 3.2GB/s Peak theoretical Bandwidth

Armed with that knowledge, because Dual channel effectively has 2 channels, it DOUBLES the read/write etc..

so, say you have 1x512MB PC3200 Dimm you can achieve 3.2GB/s, but if you have 2x512MB PC3200 in dual channel mode (requires a capable mobo) you can effectively get 6.4GB/s.

Hope that helps

Hello everyone. I recently ordered a mushkin "2GB 240-Pin DDR2 SDRAM 800 (PC2 6400)". I was wondering which config would be better 3gb running in Dual-channel at 667mhz since thats the current ram i have on the system thats what I'd have to set the new one too, rite?. Or removing the 1gb that runs at 667mhz and just using the new 2gb at 800mhz. I dont really know exactly what Im talking about so feel free to let me know anything if i was incorrect. But from what i read on wikipedia it said a bottleneck effect would happen if the processors FSB was greater than the memorys speed, so that's why I want to know which would be better.

If the Ram is rated at 667mhz, then that's all it'll ever do

I say go for the 3 x 1gb RAM at 667mhz (if you have 3 exactly the same)

How can I tell if RAM sticks are set up for "dual channel"? I've got 2 sticks of 512MB PC-3200 DDR I can purchase, but I'm not sure how to tell if they have this capability.

They're made by Elixir, and the label on the sticks read:

I have recently seen ram advertised as Dual Channel, is this a marketing ploy to get me to buy as I was under the impression as long as ram was paired (same size, etc) in the correct slots on the mobo it would run on Dual Channel anyway.

I currently have:
2 x 256mbs of ram in slots 1 and 3
1 x 512mbs of ram in slot 2

I used a program called CPUZ to determine whether they were running in dual channel and it said they were, they seem to be working fine as I have no probs running games such as NFSMW and BF2 (other than a bit of lag I put down to my graphics card). Could this configuration cause probs??

I know that it is best to have same size ram and same make, blah blah blah, but best I can do at mo, any suggestions.
 

A:Dual channel ram

To the best of my limited knowledge when running ram in dual channel mode you need two identical sticks of ram ie a matched pair placed in the same colour ram slots.

As for selling ram as "dual channel" ram it must mean a matched pair of identical sticks I would imagine.

Hi there.

In my machine at the moment, I have a bit of a mishmash of RAM, (A 512MB PC2100 stick, a 256MB PC2100 stick and a 256MB PC3200 stick) and I decided I needed a RAM boost. I plonked out and got a PC3200 Dual Channel kit (totalling 1gig).

Now the question is, what is the best config here? I have a few in mind:

Dual Channel totalling 1 gig (2x 512MB PC3200)
Single Channel totalling 1.25 gig (2x 512MB PC3200 + 1x 256MB PC3200)
Single Channel totalling 1.75 gig (2x 512MB PC3200 + 1x 256MB PC3200 + 1x 512MB PC2100)

Which of these is the best. The rig itself is mainly for gaming with an occasional penchant for Photoshop and Flash.

Any opinions greatly appreciated!

I want to pick up some more ram for my pc and it is not a dual channel type of mobo.

Will dual channel ram work none the less.?
 

A:dual channel ram

dual channel ram just works with two sticks of the same type of ram.

i have dual channel in my mb and i just bought two of the same stick and that works - if you mean to ask whether a pack of two of something would work, it will. not sure if there is a ram that will only work for dual channel.

just make sure everything else is compatable as far as what kind of ram it is (pc3200, 400mhz...etc.)

Hi torrentg......

as long as your RAM sticks timings & sizes match, you'll be running ''dual channel'', the BIOS will deal with it automatically.....all motherboards that run DDR, run ''Dual channel'' (where applicable)

so ideally you want a 2gb kit (2x1gb), but its not essential.

A:Dual Channel RAM

Well Ash, to have RAM run in dual-channel mode you should (you don't have to, put should) have paired RAM (like this Corsair) so they are guaranteed to work together in DC mode. If I may quote a paragraph :





What are some of the benefits of using paired memory? Since the memory sticks are packaged together after they have been tested together makes sure the modules that the end-user receives will be stable and perform well. Mixing different memory could lead to system instabilities or the memory modules might not run together due to compatibility issues. This takes the guesswork out of choosing memory for a dual channel motherboard. In addition, we feel that since memory speeds are not getting much faster, this give memory manufacturers another stepping-stone before moving to faster memory. Recently many other manufacturers have also started producing these paired memory kits.Click to expand...

Hey everyone,

I just recently scored myself a new motherboard in anticipation of installing a new 800FSB P4.

I'm looking into the pricing of running Dual Channel 512mg sticks of PC3200 ram...

I've noted that the price differences hover about 35-40% more between the 2. (being the dual channel supported DDR memory versus the plain jane PC3200)

Now my question is... is it really that much faster to justify the significant additional dent its going to make in my wallet?

Would a dual channel setup of 256x2 (512mg) hold its own against 512x2 (1gig) of its non-dual channel counterpart...

They are about the same price...

Maybe a simple answer but the fact that I dont know what the answer is means I have to ask. I have 2x512 running a 939 socket single core AMD 3800+ @ 2.7GHz. Installed RAM is DDR400/2x512 running in dual channel. Ive come across a stick of DDR333/512 and I would like to use it but I need to know if Im going backwards in terms of performance. As you can see my overclock is not great at all so I dont consider it a concern to revert back to stock frequency (2.4GHz) as long as Im gaining performance with more RAM. Theres no need to get specific if you dont have the time but a general rule of thumb would suffice.

Thanx
 

A:Dual Channel vs More RAM

Unless i'm mistaken ,if the stick of ram is the same spec, then on certain boards it will still use your existing ram in dual channel mode, but with the extra stick added as well in probably single channel.

This will need clarification, but i'm sure i've read or heard it somewhere.

A:Why Dual Channel?

Running your memory in DualChannel mode on a K7 platform will account at most in a 3-5% performance increase & only in memory intensive tasks.

If you can get that little extra performance for free, go for it. If you have to shell out some more money for it, it is not worth it.

The DualChannel memory controller on the nForce 2 platform was concieved to help keep all the integrated devices (VGA, Ethernet, SOund, IDE, etc.) fed with data without having to tax the memory bandwidth allocated to the CPU.

Take my advice with a grain of salt as they say, until someone who knows more corrects me... I thought that in order to have dual channel memory all the chips had to be the same size and type. I would look through your motherboard owners manual and see if it mentions memory configurations in it anywhere. I would also look at the boot up screen and see if there is a message about what mode the memory is currently operating in. Some motherboards report this information at POST.

A:Dual Channel DDR

Dual channel DDR is exactly what it sounds like. To put it simply, the chipset accesses two sticks (or channels) of DDR at the same time instead of just one. This gives a decent performance boost, but the drawback is that it requires two physical sticks of ram.

Here's a roadmap of upcoming dual-channel core logic from various companies:

Nvidia Nforce2.
Final silicon is shipping to motherboard makers. Expect first retail motherboards in the sales channel in October. It's available only for the Athlon XP processor, and will support two DDR400 channels, though Nvidia suggests that best performance will be when the memory is clocked at the same speed as the Athlon XP FSB.

VIA P4X600.
This is a dual-channel DDR chipset for the Pentium 4. It will support up to DDR333 and AGP 8X.

Intel 7205.
This is the chipset formerly known as "Granite Bay". It's aimed at the low-end workstation market, but we should see some performance motherboards in the channel by the end of the year. Note that Granite Bay is limited to DDR266, but supports AGP 8X

SiS 655.
This is SiS' entry into the dual-channel DDR chipset race. It's expected to support DDR333 as well as AGP 8X.
Springdale. This is Intel's mainstream dual-channel DDR chipset, but it won't be out until late Spring of 2003 at the earliest. It will support dual-channel DDR333 and possibly ship with a new I/O controller hub. It will also likely support a frontside bus speed of 667MHz (333MHz actual clock).

VIA P4X800.
Little is known about the P4X800, except that it was supposed to support two DDR400 channels. Given VIA's recent retreat from full DDR400 support, it's uncertain what the P4X800 will bring to the table.

Dual-channel DDR has the potential to have memory bandwidth that equals or exceeds that of the RDRAM-based Intel 850E, but only shipping products and in-depth testing can verify that. Note that even the low-end dual-channel DDR266 memory is capable of moving data at a theoretical maximum of 4 .2GB/sec -- equal to PC1066. Whether DDR266 is as efficient as RDRAM is open to question, however.

On the other hand, dual-channel DDR-333 has the potential to move up to 5.4GB/sec, something that even RDRAM can't match. We'll have to see if the chipsets can actually support throughput that high. Another issue is whether the CPU can handle the higher bandwidth. The current Pentium 4 is capable of absorbing 4.2GB/sec with its 533MHz (effective data rate) 64-bit wide front-side bus. AMD's current mainstream CPU currently weighs in with only a 266MHz frontside bus, though the company will probably move to a 333MHz frontside bus fairly soon.

HI, My m.Board supports dual channel DDR, but the manual is a bit vague...

I understand that a complimentary card in channel B will double the bandwidth, but will this also double the RAM? or is this only if both are in channel A.

The way I picture it - and I may be way off - is the 2 slots of channel A, or B are connected in serial, whereas the channels THEMSELVES are parallel.

I hope that I explained that clearly???!!!???

A:Dual Channel DDR? GA-7N-400_L

Using 2 x 512mb sticks of ram in dual channel mode will increase the bandwidth but also still give you 1024mb of system ram.

I often explain that dual channel ram operation is a similar concept to RAID-0 with hard disks.

I found this explanation over at PCStats forum





Dual channel memory works just like RAID on a HDD. Basically the two memory controllers stripe the data accross/between both sticks of RAM to allow faster access. Functionally in single channel memory the one memory controller just assigns address to the RAM and realistaically sees one 'chunk' of RAM being the sum of all the sticks. In dual channel each controller address its stick of RAM independently and allows each stick to be access simultaniously.Click to expand...

Hope this explains things
