Mixing Dual Channel Pair and Single Channel Pair Memory question

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

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

need more specs

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

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.

Ok, as of now I have two 512MB sticks of Ram in my Gigabyte GA-7N400-L board. Based on this diagnostic program I ran, it said my RAM was "single" channel (guessin that means it just regulare DDR).

What I'm wondering is, if I buy a Ram kit of two more 512MB Dual Channel Rams sticks, can I get the dual channel to still work on that set while still running the other two DDR sticks (non-dual on them of course)?
 

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..

I happened to have a chance to upgrade my ram from 1 pair to 2 pairs of OCZ Platinum Revision DDR2 PC800 2x1GB Dual Channel Ram at no cost to me after rebates. After installing these into my MSI P6N-SLI Platinum mainboard, windows vista (business x64) would not load in its normal mode.

It -would- load and recognize the RAM in safe mode. The bios also passed the ram check for all 4 GB of RAM. An attempt to run windows vista memory diagnostic from the DVD determined that there was a vague 'hardware error'. Since the RAM had passed the bios check, and since Safe-Mode recognized the RAM, I was mostly sure I had good RAM, but tested each stick by running the system not using dual channel running instead 3 sticks separately. (The 2 original and one of the new sticks.)

After doing this and the system booting successfully with each of the new sticks as the third gig, I was absolutely sure I didn't have bad sticks. After trying switching the configurations of which pairs were in which of the paired slots (though always maintaining the proper pairs together), still no positive results. So currently I am running with one new stick in its packaging, and one stick and my original pair in the machine.

I would naturally like to run with all 4 gigs of ram in the machine. I would prefer to run both pairs in dual channel mode. If anyone has any tips or can assist me in some way in getting windows to recognize all four gigs as dual channel, I would appreciate it.

So far so good building my new rig, just stumbled upon something that I guess I do not understand. So far I have bought the A8N-SLI Deluxe mobo, and AMD 3500+ 90nm cpu, and a case. Been doing some research on the memory and I came up with thinking I wanted this:

CORSAIR XMS 184-Pin 512MB DDR PC-3200 PRO series with activity LEDs, Model CMX512-3200XLPRO - Retail

Bandwidth: 3.2GB/s

After a bit of more research I found 2 things. One.. the next ram I am about to talk about scored higher in a review site and two... the Asus site says it supports the latter as two pairs of dual channel memory but it does not support the corsair one. This is the other memory:

Crucial Ballistix 184-Pin 512MB DDR PC-3200 - Retail

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.

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.

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!

Hi Guys. I was wondering if there would be any instability issues if i use 2x2GB modules in dual channel mode and another one in single channel. the reason for this is i have a faulty motherboard with one of the 3 lanes dead. So i can only ram slots 1,2,3,4 and not 5,6.

I was planning to install the rams in 2,3,4, since 1 is blocked by the CPU cooler.

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?

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.

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

Check your mobo manual, to see in which slots you need to put memory sticks to make it work in Dual Channel mode.

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:

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.

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?

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: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.

Most things out there now unless you are doing some serious multitasking or video/graphic rendering 1GB is plenty of memeory and you probably won't see that much of a differnence with 1.5 or even 2.

I have seen where there is this 10 second lag before a program responds when opening a new application using DDR4, where an i5 6th gen seems to utilize DDR3 laptop memory much smoother, instant gratification while opening up a new application. BUT, overall, while the application is up and running, DDR4 has the advantage to perform better being its at a higher frequency - 2133 HZs as opposed to DDR3 at 1600 HZs, so is there sometimes a trade off using DDR4 over DDR3 in lower ended laptops, say those who do not have a dedicated graphics card?

One more unrelated question, if I can? While swapping out a mechanical drive is as easy as they say, correct, I am not concerned about my programs I have on the mechanical drive, I just want to swap that mechanical drive out for an SSD.

A:What is Better Dual or Single Channel Memory?

Hi,

In theory a set of matched 2*8GB modules should be faster. In practice however I'd doubt anyone would notice a difference.

I have a machine equipped with DDR3 (I7 4770) and another running DDR4 (I5 6500). Not a fair comparison but I haven't noticed the impact of the type of RAM used. The amount of it, yes. Of course the I7 CPU is much more powerful than the I5 too.
Swapping a HDD out for a decent SDD makes the most difference overall.

Cheers,

I just put it 2 new 1GB memory sticks where my former 512mb sticks were.
The former sticks were 512MB PC2-4200's.
The ones I put it are 5300's and are both the same make and brand. Identical...
When I run CPU-Z it shows that I'm still in single channel... Before with my former memory sticks it showed dual... Now when I throw the former ones in there it will remain single...
Anyone know how I would go about going back into dual channel? Hopefully with these new memory sticks.
Thanks in advance.

A:Dual Channel Memory Stays in Single

Ensure that you put the modules in slots having the same colour. Dual channel slot pairs are usually colour coded. If not, then check your mobo manual to determine which slots constitute the pairs.

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.

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.

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 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?

in the DDR3 DIMM slots on this motherboard, it is unable to activate​the Dual Channel Memory Technology."

Hello,

I have been having some memory issues and I am going to run some memory checks tonight to find out where the culprit lies.

I am running 2x 500mb and 2x 1gb sticks. I believe the culprits are one of the 1gb sticks. My question is, if I find that only one of the sticks is in error, will I be able to simply remove one of the sticks and still run the other two as dual channel? I have a friend that says he's not sure if you can run a single stick of dual channel memory without it's mate (if sold in a kit). I don't know if that's true or not... so I'm coming to you guys (and gals) for help.
 

A:Dual channel memory issues and question

There is no such thing as Dual channel Ram
ie all Rams single, double or triple (whatever) will work
But your motherboard supports 2 Ram cards making Dual Channel (making them quicker)
Single Ram cards will therefore not utilize Dual Channel, but will still work

If you can get the same kit again it would be best but if you can get a kit with the same timings, speed, and voltage you should be okay.

Hey soo I have a question about installing my memory on my motherboard. These are the parts i have put together:

all brand new built last year:

Abit AX8 VIA K8T890 Motherboard socket 939
AMD 64 Athlon 3000+
Corsair XMS 2x512 DDR Dual Channel TWINX1024-3200C2PT

so basically I built this computer last year and have had the memory in slots 3 and 4. But today I was reading an article and it seems that in order to actually take advantage of my dual channel ram i need to put the memory in slots 1 and 3. I don't know why I waited so long to examine this but I was wondering if someone knew if i want dual channel support what do i have to do? What slots do i need to put the ram into?

When i tried booting up with the ram in slots 1 and 3 just as the article said..it booted up okay but there was nothing showing up on the monitor just black as if the video card wasnt being read or something. Also the boot state (number on the mother board) was CO or C0. So after this happened i just turned it off (hard stop). Just wondering if anyone had any ideas on how to get my dual channel ram working...do I need to change settings in the bios? Is my motherboard actually running dual channel with slots 3 and 4?

Any help or advice would be GREATLY appreciated! Thanks! =)
