I had MCE crashes on a Supermicro system (quad Xeon quad-core 2.4 Ghz)
that was driving me nuts for quite a while. It would take a couple of
months to crash which doesn't sound bad but it was a real pain. I bought
the machine from ASL and they worked with Supermicro to fix a microcode
The reason I mention this is that at least in this case, the BIOS version
was same before I ran the update and after.
Here is part of a message I got from ASL:
> Note that you will be updating the BIOS from version 1.0b to 1.0b. In

After updating my 1.0b BIOS to the new 1.0b the machine has been running
solid since Christmas.
So, if you have two machines, one that crashes and one that doesn't, check
the dates of the BIOS's even if the BIOS versions match.
I hope this helps.
