The IPMI firmware runs separate from the main CPU, so system memory is outside its scope. The main CPU may not even be powered up, BTW. AFAIK, the only way to access system memory through IPMI would be to send an IPMI SMS command that could be forwarded to a listening process running in the OS.
But note that system memory events, like DIMM ECC errors, could be logged into the IPMI SEL, if the BIOS is IPMI-aware.

I haven't seen it, and it's not in the standard. -corey ------------------------------------------------------------------------ ------ Download Intel® Parallel Studio Eval Try the new software tools for yourself.
