Dual-channel capable board, with 4 DIMM slots in 2 different colors--questions

Q: Dual-channel capable board, with 4 DIMM slots in 2 different colors--questions

Okay, my board is as described. I have a black bank and a blue bank. I plan on upgrading to 8 gigs of RAM this spring. With my motherboard's setup, would I benefit more from 2 sticks of 4 gig RAM or 4 sticks of 2 gig RAM?

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.

You can download it direct from this link http://downloadreimage.com/directdownload.php. (This link will automatically start a download of Reimage that you can save to your computer.)

Link us to your motherboard's website. The manual should contain the correct memory configurations.

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).

p.s. After this... I'm switching to McAfee or some sh*t.... Christ. YOU HEAR ME NORTON!? GO SUCK A FAT HAIRY LOBSTER C*CK!

I have 4 RAM cards,
2 of them are G.SKILL Ripjaws 2GB 1866 (PC3 14900)
The other 2 are G.SKILL Trident 2GB 1866 (PC3 15000)

Here is what the manual says
It says, put matching pairs into the same colored slots.
Slots 1, and 2, are white, and slots 3, and 4, are blue.
Am I supposed to put the matching pair in the same colored slots?

Then it says
Channel A: DDR3_2, DDR3_4
Channel B: DDR3_1, DDR3_3
Am I supposed to put one pair into Channel A, and the other pair into Channel B?

I'm wondering if they made a typo about putting the matching pairs into the same colored slots, because then they would be on different channels.....

Am I better off putting one matching pair into channel A, and the other in channel B, since the RAM cards are slightly different?

A:Which slots for 2 different types of RAM for Dual Channel?

Put them as pairs in the colored slot to match, the computer will see them as being the same speed and dual channel.

say I have a server board with 8 slots for RAM. For fastest performance with 4G, I should use 4x 1G spread across 4 slots? Rather then 2 x 2G across 2 slots? Now, would the performance decrease if I went to 6G, since there is an uneven amount of channels in use? Would appreciate any insight and links regarding this. Thanks
 

A:Dual Channel RAM on Server board

I remeber this topic conimg up before, and I had a gave a fairly detailed reply. The long and short is that it wont make a lot of difference either way, the best thing to do is go with whichever is cheaper.
For the tech bit, the 1 gig sticks have a slightly faster responce, but usibg 4 sticks instead of 2 means the overall bandwidth is effectively a bit less than that if you use 2 sticks. In real terms, these differences are about the same, but both extremely small, so it doesnt matter that much. For 6 gig, I would say 6 1 gig sticks, as you could keeo the pairings and not lose any timing cycles. If you can go to 8 gig, 4x 2 gig sticks would probably be slightly better, butagain, in real terms the differences are so small, it would take a pretty good man to see any

I recently bought a 8 GB ram stick for my laptop.

My laptop has a soldered 4 GB ram stick and only 1 free socket.

Can dual Channel still work properly if both sticks are of different brands and capacity ?

Or are there any other setbacks ? =/

soldered Ram - Samsung 1333mhz 4 GB 1.35v

Removable Ram - Kingston 1333hz 8 GB 1.5v

A:Dual Channel ram questions.

no both sticks woukd have to be identical. the kingston ram will run undervolted so will probably run at a slower speed than 1333mhz, which will lower the access speed further.

A:Questions about two sets of RAM (dual channel)

1.Older AMD Athlon 64 systems sometimes would clock down to 333Mhz when all slot were populated. Generally you just have to go into the BIOS and bump the speed back up to 400Mhz.

2. You can still run in dual channel

3. To maintain best dual performance you need to keep them in pairs, so just add the 1GB's to the empty slots.

I am currently running XP, and I have dual channel memory.

Right now I have x2 1GB DDR2 RAM chips (so 2GB of RAM)
They are in the corresponding slots.

I'm thinking of getting more RAM, but because XP can only see up to below 4GB of RAM, would it be better to get 2 more 1GB chips? Or just one 2GB chip? (I can get 2GB cheaper)

If I was to have the two existing chips running on dual memory, am I still able to just put in one more chip of ram, while leaving its other corresponding slot free?

Thanks a lot.

I have noticed a steady progression of either bad Dimm or Dimm slots. In the last 3-4 years as computers come to our shop I notice that people are complaining about lock-up problems and you go inside the machine and thump the ram chip and the machine will either reboot or give a hard lock-up. So my question is it bad ram contacts, bad slots or just cheap metals ? I have machines that are 8-10 years old and no ram problems at all that are still solid as a rock. The problem does not seem to be one certain manufacturer.

I believe you get better performance by having a 512 MB module in all 4 slots instead of having a 1 GB module in 2 slots and leaving the other 2 slots empty.

I am troubleshooting a Dell GX620 (small form) because of faulty RAM beep and number codes. I reseated both 1GB modules and still got the error. I tried one at a time in the original (DIMM 1 and DIMM 2) slots and still got the error on both. When I switched to DIMM 3 then one of the modules would work: post and boot into the OS - no problem. Now, I understand that one of these modules is probably just bad. But why would one of them work only in the DIMM 3 slot and none of the others? Are the DIMM slots bad on the system board? Thanks in advance for any help.

A:Faulty DIMM slots?

Does the other module work in DIMM3 or DIMM 4? You could just put the modules to slots 3 and 4, if they work in them. But, if your warranty's not over, you should get a new one, because of the faulty memory slots. Have you been using this computer for long? Are all the parts stock ones?

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?

Is it possible that you need to flip the RAM modules 180 degrees? The notch in the insertion end is not in the middle so it will prevent the RAM from seating if you insert it backwards.

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?

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.

A:Dual Channel Suddenly Stopped Working, Only Single Channel Remains

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.

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.

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 guys,
I want to purchase more ram sticks for my desktop. It already has 3GB in it. 2x1GB sticks and 2x512MB sticks. I would like to take it all the way to 4GB. 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?

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.

Win 7 64bit and Win 7 32 bit partitions.

I recently added 64 bit partition to run more RAM, so the slots 2 and 4 will have gotton dust in it as it was unused for ages.

If I wiggle the slot 4 in sometimes I get 8gb and dual channel RAM.

At the moment I have single channel and on 4gb, does that mean I am using 1gb of each of the 4 slots.

The ram is ddr2 2gb sticks x 4.

Do I need to clean the slot?

also Java based apps are crashing on 32bit and 64 bit.

Just clean the slot? what with, whats the best approach?

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?

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.

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 all,

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.

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.

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?

Is it possible to fill all of the memory slots on a motherboard that supports dual channel with non-matching ram (one chip at a time as I need/afford it)? If I just put more ram in will the motherboard recognise all of it and just not take advantage of the second channel, or will it not recognise that non-matching ram in the second channel sockets?

Thanks!!
 

A:Dual channel RAM in single channel mode

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.

2) I will be buying a new drive for my PC soon. I have been told that SCSI is the better buy. Can you provide info on SCSI -- is it a higher end drive, more popular, better performance, better buy based on size, etc. compared to IDE?

3) If one installs regular DIMMs on a motherboard rather than the particular ones supported by the motherboard, would it cause any damage? Or is it not possible to do this because of the size or placement of notches of regular DIMM vs. DDR DIMM?

Thanks much!
 

A:Win98, SCSI, and DDR DIMM questions

To install the shared printer on each machine, use the add Printer wizard on each one, and yes, you will have to load the drivers on each machine.

To use a SCSI drive, you have to use a SCSI card . . My experience is the modern 7200rpm IDE drives are virtually as fast as SCSI drives . . and not woth the bother.

Memory modules have diffferent slot configurations and will only fit in the slot it is designed for.

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.

Keep in mind that in order to perform in dual channel you need to sticks of the exact type of memory - "matched pairs" (same speed and latency).

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.

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.

Yes. I take it you mean triple channel memory kits. If so, you would use just 2 out of the 3 sticks. However, dual channel DDR3 kits are available.

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?

Thanks for the help.
 

A:Mixing Dual Channel Pair and Single Channel Pair Memory question

does your mobo have 4 ram slots if so use the 1st and 3rd that should run it in dual channel !!

also make sure you on have 2 sticks in not 3 :slurp:

and the answer is to your question what ever the lowest speed ram is. the other ram will be clocked down to run at that same speed the lowest speed
takes the rains !!!
and you will notice the difference running dual chanel

but for reall speed difference ditch your ram and buy GEIL ULTRA

I was checking to make sure I have 4 ram slots the other day. I found 4 slots, like I figured I would. 2 had ram sticks, but the other two were not empty. They had small plain sticks in them. I'm almost positive there was nothing on them, just plain plastic circuit board. So are these some kind of filler or something? Just so there's something in the slot... or are they something else? Just wanted to make sure before I buy 2 more sticks of ram.

A:Quick Questions about RAM Slots

RAM does not need to be installed in pairs, except for old and obsolete RAMBUS. However it usually is to benefit from something called dual channel which can increase memory bandwidth.

You should test the RAM with Memtest86+: http://www.memtest.org/

And try the one you think is faulty by itself and with the rest of the RAM.

Should I stick with that, or should I use the onboard sound [is it dolby 5.1? ]? If so, what speakers should I get? (under 70 please)

Is it worth using the onboard sound or should I save for an Audigy 2?


BTW - will one reduce system performance more than the other?

No longer cracking in sound when copying files, no more slow file copying, no more system crashes...

So in short, use it instead of your 128... I'm not quite sure when it comes to Audigy... The Q is, how good are your speakers? If they are of a premium quality, you might get a bit better sound with the Audigy, but if you're just using a set of OK speakers...

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.

Using 2 video card slots gives you the ability to use multiple monitors but the main reason for their existence is gaming performance. Both top GPU manufacturers, ATI/AMD and NVIDIA provide the ability to combine 2 identical cards for increased 3D performance. These technologies are called SLI for NVIDIA and Crossfire for ATI/AMD. So, of course you can use 2 cards with one monitor if you like!

The m/b you chose has pretty good features and uses a nice chipset. In case you decide to use a dual GPU configuration make sure that the P35 chipset supports both companies. Some time ago intel chipsets could only use crossfire.

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...

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.

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,

I have 2 sticks of RAM. Different size, same vendor.

Corsair 4 GB PC10700 667 Mhz
Corsair 2 GB PC10700 667 Mhz

Installed on Windows 8.1 laptop. Windows sees 6 GB RAM.

I opened CPU-Z and it says Channel = Dual

Does this mean Dual Channel mode enabled at the moment?

A:Dual Channel RAM

If I remember correctly 2GB of each channel will be Dual and the remaining 2GB will be single channel.

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.

I have a pair of 512 mb DDR on my Dual Channel mobo. if i was to increase ram in my system, would the other you ram sockets need to same 2 that i've already used? or can i get two 1gig sticks to make dual channel in the second 2 slots?

make sense?

I am using 2 Ram stick of Transcend & Apacer brand in dual channel of my Gigabyete motherboard. It was performing well for 8 months without any trouble.But suddenly it is taking too many times to load any operating system.If anyone tell me what to do about this problem,plz

A:Dual Channel RAM

Download Memtest86+ and make a bootable USB stick with it, reboot and go into the BIOS and force it to boot from the USB stick. Let Memtest run for at least a few hours or until it throws errors(if it does). If there is a RAM problem, Memtest will find it more than likely.

Here is a tutorial that will walk you through this process. How to Test and Diagnose RAM Issues with Memtest86+

can i use pc2700 in dual channel mode? or do i need pc3200
 

A:dual channel

no i'm keeping my pc2700 i just wanted to know because i might be getting a prescott (depends if it's better than the 64) and i've heard that the dual channel on the p4 is great so i think it'll be tha same with the prescott

Im jus wondering what the gain in performance would be,or if thare is any. Like if i have two 256meg sticks in dual mode or one 512meg stick in regular mode.
Is dual channel better? if so why?
keeping in mind more than 512meg would be overkill in my use of my PC.
Just wondering
thanks all
 

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.
