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 have a problem and I think it s memory related I read the post about quot Dual-Channel Memory in Single-Channel Motherboard quot But it didn t help plus it was memory channel Dual board? single in Channel from Here s my computer it s old I know I don t have the money to upgrade all of it - Intel Pentium D GHz - EVGA GeForce GS MB GDDR PCI Express - Intel D GGCL ATI Socket Dual Channel memory in single channel board?

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.


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!

Hi Ive been having trouble 100% / Ram not Channel Dual Slots with the RAM on my PC for quite a while so ive finally decided to find out what the problem actually is Basically i run my System most of the time with x GB Crossairr Sticks of Ram For Dual Channel not 100% / Ram Slots a while now ive been having unstable and unsuccessfull boots using Dual Channel When Sticks of ram are installed the system will sometimes not post but when i remove one stick the system boots and loads fine When i boot the system with Stick of ram the system boots fine always but when i have in it sometimes wont boot The way ive found of getting it to boot Dual Channel not 100% / Ram Slots with sticks is to remove one boot the system with stick shutdown reinstall stick and boot PC this works sometimes and the system will Post but others it wont even post Ive tested the both ram sticks individually with the system and they both work individually however that depends on what slots they go into For example i have one ram stick that gets detected in DDR but not in DDR slot The other stick works in both slots A Side symptom im getting is the PC gives me a lot of errors talking about the checksum being different Not sure if that relates I hope you guys can help me out with this its really starting to annoy me now Full Specs Windows Ultimate bit ATi HD Radeon GB x Gb Crossair RAM Gigabyte G M-ES L Intel Pentium D Ghz GB Sata HDD GB IDE HDD Thanks Zippyo nbsp

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?

The two DIMM slots in a C600 a customer brought in look slightly different at the key in the slot and I cannot fit anything in Slot 1, just Slot 2. Is there supposed to be a difference? (FWIW, Slot 2 has "Foxconn 0129" written on it and the other slot has "Foxconn 0128".)

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 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.

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.

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.. 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.

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.

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.

My system is abit IP35 quad core 2 q6600 running 4gb of RAM, all the same spec.

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.

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 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?

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 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?

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?


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.

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.

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 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.

I have Windows 8.1 32-bit installed and have fitted my PC (Dell Inspiron 531) with 4GB RAM.

The system only reports 3.25gb as usable - where has the remainder gone?

Is it the Graphics card (ATI Radeon HD 2600 XT)?

I understand that Win8.1 32-bit can utilise a full 4GB of RAM?

Also in the Task Manager, it reports that I have used "2 of 2 slots", however I have 4 RAM slots inside the machine where the RAM is fitted (4 x 1GB fitted).

Any help?

Hello I just registered on this board after learning a bit about dual channel memory from posts here Didn Channel memory & Dual P-805 Core Dual t learn enough though First off thanks for the scoop on why dual channel doesn t work with Athlon XP I once had it in an ASUS board Dual Channel memory & Dual Core P-805 that was supposed to run dual channel I could not tell the difference in performance when it booted up in dual channel mode vs single channel The BIOS displayed Dual Channel memory & Dual Core P-805 which it thought it was running on boot-up I am now building up a system with a Pentium D in a ECS P M Pro-M mobo This is claimed to support Dual Core operation A couple of general questions Regarding Dual Core and Dual Channel Memory operation Dual Channel memory & Dual Core P-805 are they totally independent Will both features work together or can you just get one or the other or neither on this combo I see NO mention of dual channel memory in the mobo manual I plan to run Win on this machine Does that support Dual core Dual Channel or both Or are these modes totally independent of the operating system software My understanding of Dual Core operation is minimal I guess it means you could have one core running MS Word while the other runs MS Excel or plays a game Is this correct If so is the operator in any way aware of the machine operating in this mode or have to do anything to make it operate in the dual core mode Or is the operator totally unaware of the dual core operation except for hopefully better performance Should I be looking to stuff the memory in this mobo with quot dual channel quot single-sided pair of DDR PC dimms MHZ for best performance the top mobo rating If so is there any reason I should NOT use PC MHZ dimms for the sake of possibly overclocking or using them in a faster mobo in th future I am currently using PC dimms with an AMD Sempron in a MSI mobo rated only for PC memory It is working fine In general I would guess faster memory would work in a slower system but I don t really know that can be expected in all cases I realize this is a lot to choke on all at once My apologies and thanks a bunch nbsp

A:Dual Channel memory & Dual Core P-805

Faster memory will work at a slwer speed, you can use both at the same time, and I think your Mobo supports Dual-Channel, but im not sure. You will notice the differance either way with more memory.

So I'm working on a PC rebuild for work. Specifically the computer used to go graphic design for signs, which is rather Memory intensive (4ft x 8ft raster graphics take up a lot of space to load into Photoshop.....)

But what I'm wondering is Tri-Channel memory really worth the additional cost of the RAM and Mobo??

Or should I just stick with dual channel?

A:Dual channel vs tri-channel

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 own an HP Kayak with dual slot 1 -- which can support upto 500mhz p3 processors in them. i have tried several pairs of p2 400mhz and 350 mhz as well as 500mhz p3 pairs. but i have been unable to achieve the simultaneous working of 2 processors. every time when i checked the performance by any diagnostic software i found out that only one of the pair is working. i have been using win xp pro.

can somebody guide where i am making the mistake which fails me in achieving the performance by the dual processors.

A:rebuilding precision T5400 dual xeon x5450 ram problem - 1-3-2 beeps cant install more than 4 out of 8 dimm cards

Hi all,I`ve had a play around with the new ram sticks that came this morning and no difference.
Not to be defeated I played about and have managed to install a pair in slots 7&8 which actually works giving me 24GB which may be enough but I`m still confused as to why putting the 2 sticks from 7 & 8 (which are obviously matched and working) into slots 5 & 6 causes the thing to not boot, I have  verified slots 5 & 6 work by putting a single stick into each on subsequent boots and they definitely show up in the bios set up but are not used as they are not a pair.I have come to the conclusion that this is a bios fault and will try flashing the older A09 release and post back.

Just a quick question that came up in my head while I was reading the chapter about RAM in my hardware book... assuming that I'm building a gaming computer for myself with an i7 CPU and x58 chipset, what would give me better overall performance.... installing 4 memory modules of 2GB each and running on dual-channel mode or installing 3 memory modules of 2GB each and running on triple-channel mode?
thank you

A:8GB DDR3 (dual-channel) x 6GB DDR3 (triple-channel) Which is better?

Depends a lot on how much RAM your applications need. Triple channel is slightly faster, but if you. Err. Run two instances of Crysis, then you might need 8 GiB so the other solution is 'better'.
My vote goes for 3x2...

Hi i am building my own computer (1st time),

I was considering buying the Gigabyte GA-EP35-DS3P motherboard as i want something suitable for gaming, hd movies, multitasking and a bit of everything.

The only issues i have with it, is that it has 2 PCI slots and i would prefer 3, but its not essential and that it has 2 video card slots.

I am also planning to buy a high end video card.

First off, Is it beneficial to have 2 video card slots when only using one monitor?? Can you even use 2 video cards with 1 monitor??

And is this a suitable motherboard choice?? Bearing in mind that i hope not to upgrade for a little while.. if not could anyone please suggest some others.

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.

Ok, so my motherboard died. I want to buy a new board, and CPU. Now I have 3 chips of DDR ram, 2(256mb), 1(128mb), all at 266mhz. The motherboard i have been looking at has a nividia nforce 400 ultra chipset, and 3 sockets for DDR Dual-channel ram. Now if i install the 3 cards of ram i have wouldnt it just read it has single channel, not dual, but it would still work and read 640mb ram right? The reason i ask this is b/c i have been told that NON-dual channel ram, will not work in a dual channel motherboard. Need some help here guys, thx...

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...

I may want to up the memory on my machine from 1 GB to 2 GB which is the mainboard's maximum. It is an MS-7211 from MSI. Here is the only thing the manual says about memory:

Main Memory
? Supports two memory banks using two 184-pin DDR DIMM.
? Supports up to 2GB PC3200 (DDR400) SDRAMs.
? Supports 2.5v DDR SDRAM.

I want to get dual channel ram. Can anyone tell me if they know it is guaranteed to work? Or do you need a special motherboard for dual channel?
Facts definitely welcomed and so are educated guesses too. Thanks.

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.


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

I am planning on upgrading my machine with an Intel D875PBZ, this board supports dual channel ram. I do not do any gaming on my system but plan on doing video editing. Is it worth while to go to the extra expense of dual channel or should I purchase another type of board with out dual channel support, (cheaper)? I also plan on using a 3gighz processor and 1gig ram. Without the extra expense of the dual channel ram I could buy another 512megs of normal ram.

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.


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.
