is it a problem with the CPU, the Memory or the Motheboard ?

I started getting those same errors recently on a dual-Opteron, one
of the
sticks of RAM was going bad. Looking in the BIOS' log also showed
single-
and double-bit memory errors. I pulled out the memory attached to the
processer in question, and all of the problems stopped.

hi,

i think that the problem is the motherboard, i've tested with one stick of
ram on the three slots with no problem. i've tested the other stick with
no problem.

when i put the two sticks (tested on all slots), my linx falls... ;(

i don't know if i still have a guarantee for this motherboard but i'm
going to contact asus nearly.

thanks all.

Back up critical data before system failure. IMO, it's memory.

The problem sounds like both sticks will not work together. Are both
sticks of memory exactly the same? Memory from different vendors
sometimes don't play well together, especially value ram versions.
A simple solution is to run with one stick, system will be slower.

Run Memtest86 on both sticks of memory together for at least an hour.

I suspect faulty memory or psu before defective motherboard or cpu
failure. Temps do not look excessive, AMD XPs run up to 70C.
