RAM talks to the chipset so I dont think it could (unless it confused the

Ok that decodes as:
Status valid
Uncorrect Error
Error Enabled
Processor Context Corrupt

Memory Heirarchy Error
Instruction Fetch
L1 cache

More than that I can't really say. Power and heat problems can certainly
trigger MCE's. I don't know if I/O devices can influence them.
