Twin sets of Dual Channel ram

[DataMatrix]

I know this is a long shot and I know it probably doesn't work, but if it did and I don't find out... then my loss.

But can 2 sets of my ram (exact same sets to make 4 modules of the same ram) still work in dual channel mode?

I haven't bought the other set of modules I'm just using 2GB right now but if I can get 4GB and still have dual channel mode, that would be awesome.

Thanks.

4x1GB will work in dual channel, they are matching pairs.

So say if I buy another 2 x 1GB of the EXACT same ram, then I will have 4 x 1GB will I still get dual channel?

[redddraggon]

2 different matched pairs should work in dual channel.

yes if your motherboard has two dual channel rails as it wouldn't run as 4x1gb in dual channel it would run 2x1gb+2x1gb

Search they forum for more info - they dont have to be matched. Just means you might get less problems.

Okay, thanks people.

I have one last question.

Instead of me buying more shrivelling old memory for this old 939 motherboard. I have decided to get C2D E6700 and 2GB Corsair TwinX 4-4-4-12.

The motherboard I will be using is Abit IN9 32X-MAX WiFi NF680i SLI.

Can this motherboard use 2 sets of DDR 2? Or shall I buy the 2 x 2GB set?

Edit: Scratch that, I'm unsure of which motherboard now. What do you suggest?

Check with who you are getting the memory from

For example crucial:
http://www.crucial.com/store/listpar...%2DMAX+Wi%2DFi

the page states the M/B suports 32GB but the page also states:

Each memory slot can hold DDR2 PC2-6400,DDR2 PC2-8500,DDR2 PC2-8000 with a maximum of 1GB per slot.*

*Not to exceed manufacturer supported memory.

If you are running a 32bit OS you will be unable to use all 4GB you need a 64bit OS for that. If you are going to have 2 x 8800GTS installed on a 32bit O/S check google out - if your video cards have total memory 1.5GB you will only be able to access less than 2.5GB of system ram.

If you are running a 32bit OS you will be unable to use all 4GB you need a 64bit OS for that

The OS has nothing to do with being able to address up to 4gb (32bit windows can happily do that) - that's a hardware issue, not an OS one.
If the mobo has PAE support, you will be able to use all 4gb. If not, then manwithnoname is correct - you will have less available. Just to make it clear though - this is a hardware restriction, not a OS one
