Single-sided + double-sided on dual-channel: incompatible?

post #1 of 6
Thread Starter 




Hi, I was using four DDR2 memories (3x1GB + 512MB) then I updated to DDR3 (4GB + 2GB). This is leaving the system to constant program crashes and blue screens (after entering Windows and using for a while). As you see, MemTest86+ doesn't indicate any errors, while MemTest says the pair is unstable. They were used on other machines with no problems.

Today I updated the BIOS version from 2002 to 2103, with no results.

According to CPU-Z, the dual-channel is symmetric. o_O

ASUS P5QC
KVR1333D3N9/4G + KVR1333D3S8N9/2G
Q8400
CX430

Thanks! x_x

First the warning:
Always buy memory in matched sets.

Single sided and double sided have nothing to do with single channel nor dual channel.
Single sided and double sided have nothing to do with which side of the sticks the ICs are on.
Running double sided memory on a motherboard that only supports single sided memory results in the motherboard only seeing 1/2 of the double sided memory's size
Running single sided memory and double sided memory together results in the motherboard running the double sided memory at 1/2 it's speed.

Do you know what memory timings are and how to read what timings memory is running at?

No, but I have set manually the timings, with no results.



According to manual, the motherboard supports some DS memories, and this guy is using two Corsair 4GB, which is DS, I think:

I don't think he knows what he's using. That's why I asked the question about timings.

Now I will try with the 2GB module, I hope it works.

UPDATE: Just installed chipset drivers from the ASUS's site and some network drivers from CD and is running fine, the 4GB stick alone.
