to finish an old mail thread:
I added three additional fans to my case (specially silent ones) and I
installed a memory cooler (a small fan blowing on the memory banks). And
now things work fine. I can reduce the speed of the CPU cooler in the
BIOS and my machine runs stable even during the summer heat.
So, all in all I conclude that it was the missing cooling of the memory
that really made my box unstable.
Thanks for the advice.

Umm, which flavor of OCZ do you have? There have been problems in the past
with the SPD programming and the PLL's on the model OCZ400512ELERDC-K.
I have 2 GB in my system. They are the 4th or 5th set. Eventually they
ironed everything out and their tech support people were great. However, at
the time I was talking to them (January?) their position was that they did
not officially support Opteron, only Athlon64/FX. (Yes, I realize that the
memory controllers are identical. You try to tell them.)
If these are what you have you might try slowing them down. I don't know if
that would help - my mobo's BIOS (Tyan s2885) does not support memory timing
already considered putting some fans into my case.
I give it a try in
the next weeks and let the mailing list know whether this pays off.
Supplemental cooling is not a bad idea either.
