Hello, I have Two Mushkin's 2GB DDR2 each, they are at 800Mhz bus speed, have a latency of 5-5-5-18 and a voltage of 1.8v

On the other hand, I have two TwinMOS 8d25kk-tt 1GB DDR2, 800mhz bus speed, unknown latency and unknown voltage.

I run perfectly good with the Mushkin's, but merging them with the TwinMOS, during boot the computer crashes and restarts automatically when starting to load the windows 7 64 bit, even before the boot screen.

I know its an obvious incompability issue, but is there a way I can make a tweak in the bios?

My motherboard is GA-N650SLI-DS4l.

Thanks in Advance.

Even if you had bought an identical Mushkin set to the one you already have, there is no guarantee the two sets would play together.
I'm assuming you have put them in correct slots on the motherboard. You could remove the Mushkins and try to boot with only the TwinMOS sticks. That way you can either check their properties in BIOS or have a look with CPU-Z and/or Sandra.

I forgot to tell you guys they worked perfectly fine toghether on my previous 32bit OS (windows 7 hp)
but i had to install a 64bit OS because of the memory limit (3.0GB)

On these sticks there are a few codes labeled.

P/N: 8DP25KK5UTYTP
MODEL NO 8D25KK-TT
S/N: 740M75MD0980423
PC2-6400 1GB U-DIMM/CL5

I hope that gives you the hint.

update: thank you all for the suggestions but I found the problem, and the system is currently running on a 6GB RAM on a 64bit os.
The problem was the ram module placement, instead of:

MUSHKIN
TWINMOS
MUSKIN
TWINMOS

I have sorted it:

MUSHKIN
MUSHKIN
TWINMOS
TWINMOS
