Dual Channel DDR on NON-Dual Channel Motherboard, will it work?

Q: Dual Channel DDR on NON-Dual Channel Motherboard, will it work?

Hey Everyone,

I am brand spankin' new here, and I have a question for someone out there. I currently have a SOYO motherboard (which I have been having issues with) and I am going to be switching to a ECS Elite Group board in a few weeks. My question is, when I bought RAM for my SOYO I bought Patriot Dual Channel DDR 3200 1gb pair, but the ECS board I am switching to does not support Dual Channel, so can I still use the the 2 512 sticks normally on the new board or I do I have to get new memory or a different board? I would think it would just run them as 2 sticks of 512, but I am not sure and I wanted to know if anyone else knew this or not?

Thanks in advance for any help (and sorry if I missed this being posted somewhere else, I did try and search for the answer but didnt see anything).

Would it just clock the ram down and if so would there be a huge performance hit?

A:Dual-Channel Memory in Single-Channel Motherboard

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.

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?

There are several cases I've wanted to install memory in pairs to achieve dual-channel memory speeds, but I've come across a caveat or two about whether or not this is worth it.

Questions:

How do I calculate whether or not the FSB is fast enough to take advantage of the memory speeds. I'll see cpuz refer to things like FSB:memory as "1:2", which I'm not sure refers to the memory controller taking advantage of the up and down side of the clock waveform, or if it's saying "give up, we're half the speed we need".
How do I calculate dual core beasts? Do the internal 2 "processors" share the FSB, or do they each have their own resulting in double access speed [attempts] to dual ported memory (note, not dual channel).
Forgive me please, my questions may be tripping all over themselves. It's been a longgggg time since I've calculated any of this out during my stint as a DSP software engineer.

I'll be glad to rephrase this in any way you all like.

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.

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 "lights are on, but no one's home" 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 ones home deal again.

Now before this I had been having memory problems, with blue screens saying "memory management" and "IRQL not less than or equal". So I thought it might be a bad strip of ram, and even bought two 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 8GB'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. 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 1 and 3 for a single channel configuration. Didn't matter which set of ram I used, ju... Read more

Single channel Nforce2 400 dethrones its dual channel stablemate

quote:
" ... ENTHUSIAST SITE amdmb.com discovered this unexpected anomaly, which could have far reaching Socket-A repercussions.

Soltek's bottom dollar SL-NV400-64 motherboard, which is based on the single channel nForce2 400 chipset, is the cause of all this news. What is amazing is that it beat Asus' dual channel flagship product - the A7N8X Deluxe, in the majority of benchmarks. Ryan Shrout, the amdmb.com reviewer, who put Soltek's motherboard through its paces, suggests that its performance lead in UT 2K3 is down to the additional overhead that a dual channel system board has to deal with. Looking at the rest of the results, I would apply that comment as a general across the board statement.

Soltek's motherboard retails at a new egg price of $76 - the version without LAN will apparently be sold for under $70. Asustek's $130 flagship adds an additional $54, which would buy you a Thoroughbred 1700+ and its cooling kit. Will this more for less attribute drive more enthusiasts to buy Soltek's better performing solution?

Soltek's overall performance lead is not earth shattering, but like everything else in this industry, perception is everything. Of the 14 benchmarks that were run, Soltek's board won 11 of them, drew 2, and lost only one. For the record:

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.. 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, 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.

I have a problem and I think it's memory related.

I read the post about "Dual-Channel Memory in Single-Channel Motherboard." But it didn't help, plus it was from 2005.

Here's my computer (it's old, I know. I don't have the money to upgrade all of it):
- Intel Pentium D 820 2.80GHz
- EVGA GeForce 7300 GS / 256MB GDDR2 / PCI Express
- Intel D101GGCL ATI Socket 775 MicroATX Motherboard
- 1 GB (2 x 512MB) PC3200 DDR 400MHz CL3 Memory
- Ultra 500-Watt power supply
- Windows XP 32bit

I recently bought a memory upgrade:
2GB (2 x 1GB) 184-Pin DDR SDRAM DDR 400 (PC 3200) Dual Channel Kit

My computer worked fine (minus the small memory amount) before I installed the new memory. After I installed the new RAM, my computer posted, got to the windows splash screen, got to the log in screen, let me log in, then loaded the OS. While loading the OS and launching other start-up programs, my computer froze. I restarted many times and it fixed it. It never got past a few seconds after loading the OS and a few programs.

I reinstalled my old memory and it worked fine again without a hitch.

What is the problem? Is it the fact that the new memory is dual channel and the motherboard is single channel? I re-read the specs of my mobo and it said that dual channel is optional. However when I go to the BOIS menu (F2 on startup) it says "single channel mode" whith the new dual channel kit is in. Is there something in the BIOS I should cha... Read more

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... Read more

I'm facing an unusual predicament at the moment. I currently have Windows 7 Ultimate installed on my custom tower. The tower runs an Intel Pentium 4 2.80 ghz, the OS is 32 bits, and initially was installed with one gig of RAM (2 512MB sticks) dual channel (DDR [1]).

Windows 7 wasn't sluggish, surprisingly, and I used the upgrade advisor to determine if my system was ready and I found it was. I was hoping to add a little "juice" so I tore into an old system and found a 1GB stick of DDR RAM. Now, I can change the dual channel configuration to single channel operation and run 2Gigs of RAM or I can keep the dual channel at 1Gig.

I've read on Tom's Hardware that the difference wasn't noticeable in dual vs. single but I also know that my processor was built for dual channel. Are there any recommendations? Make the single channel upgrade or keep the dual channel configuration?

At some point I will likely purchase another chip but for the time being I'm curious about anyone who has been in my position or knows memory well enough.

Thanks for any input!

If you look at the motherboard manual, there may still be a way to run in dual channel with only 3 sticks, if it`s possible the MB manual will show you which slots to populate.

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.

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..

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.

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?

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:Dual-channel vs. Single-channel memory

Yep, although the actual effect may not be that noticeable. You are cutting the memory bandwidth in half.

Greetings

I am considering buying dual-channel ram for my computer - am in the process of upgrading, so have been conducting my own private research on various hardware I have spent quite a while looking for information about dual-channel ddr-rams, and this is what I have discovered:
You need two blocks of the same size and type, and preferrably made by the same producer
Your motherboard needs to support the usage of dual-channel ddr-rams

Now, what I don't know is this:
Is a RAM block which is specified as being dual-channel any more suitable for use as a dual-channel RAM block than a RAM block not specified as dual-channel? why? what's the difference? I have only seen Corsair producing rams with the "dual-channel" specification, but have read about people dual-channeling Kingston RAMs...
How much memory will I end up with? Let's say I get a set of 1GB RAM blocks from, say, Corsair (by a set, I mean two ram-blocks). I put them into my dual-channel motherboard, enable dual-channel ram (should that be necessary) ... then, do I get 2GB RAM which works slightly faster than a set of ram which doesn't have dual-channeling enabled? Or do I get 1GB RAM, making it work similar to RAID where all data written to one RAM block is also written to the other, so that any data can be read from both RAM blocks simultaneously?

Bonus questions what do the following terms mean, in short?:
unbuffered (what did the missing buffer priorly do?)
ECC (my mothe... Read more

Hi All

I would like to know the requirements of dual channel architecture RAM:

Here is my understanding:


- Dual-Channel Architecture uses Banks consisting of pairs of RAM slots (2 slots per bank)
- Both Slots must contain a RAM DIMM (Stick) - eg. You cannot put a single RAM DIMM into a dual channel bank, both slots
must be filled...
- RAM DIMMs in a bank(matching pair) can have different speeds BUT the slower RAM speed will be chosen...
- RAM DIMMs in a bank(matching pair) can have different sizes/capacities(eg. 1x2GB and 1x1GB)
- RAM DIMMs in a bank(matching pair) MUST be of the same type - eg. DDR, DDR2, DDR3 etc

Am I correct on all my 'assumptions'?

Thank you

A:How does Dual-Channel RAM architecture work?

Some of your assumptions are true regardless of what type of chipset they are going into. But I think I can clarify.

A dual channel refers to two slots working as a bank. So in those two slots, you will want to have matching pairs (as you said). Matching pairs means the same memory...same type, brand, speed, capacity, etc. If you mix memory, you run the risk of it not functioning properly. Anytime you mix memory, you run that risk of instability.

Considering the fact it's been 8-10 years since memory has been available in pairs or kits, there's no reason anymore NOT to use matching pairs. You can mismatch across banks, though. For example, I have 4 memory sticks. They are identical in ever way, except I have 2x4 and then 2x2 for a total of 12 GB. All memory is the same brand, speed, timing, etc.

Did you built the PC yourself?
I would first check if they are put in the place correctly, and not backward or something (I did it myself :lol) both little flaps should be folded down.
If they are, remove one module and try to boot that way, then try with the other 1 in another slot.
Keep us informed!

i've tried a total of four different kits of ram in dual channel on my computer, and my computer wont stay on in windows for more than a minute without restarting. not BSOD, simply restarting. However, it runs perfectly stable in single channel mode. my motherboard has the color coded ram socket things, and the manufacturer's website says it supports dual channel. any ideas?

here are my specs

ABIT ic-7 max3
3 hard drives (150 gig, two 80 gigs, two connected with IDE, and one connected with SATA)
nvidia 6800 ultra
intel pentium 4 running at 3.01ghz
currently, i've got one OCZ kit (2x512) and one Crucial kit (2x1gb) and neither work in dual channel mode. they're 184-pin DDR ram modules, both PC3200

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 recently purchased a 1gb stick of ddr400 (non-ecc) dual channel ram. i have a dell 8300 with 2x256mb single channel ram sticks. i tried to replace the 2x256mb sticks(ddr400) with the 1gb stick in DiMM 1, this resulted in beeping of the pc and it not booting. I also tryed the 2 256mb in DiMM 1 and DiMM 3 with the 1gb stick in DiMM 2. Whichever way i try it my pc refuses to read the 1gb stick. Im running windows xp. do i need to purchase a second 1gb stick for DiMM 4?

thanks in advance this has been bugging me for quite some time!

A:triple channel ram with dual channel MB

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.

Which motherboards were you looking at?

First of all does your mobo support dual channel? AMD socket 754 do not support dual channel. I have a 754

Here is an article that answers all of your questions...

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).

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.
