Get a program called cpu cool ( or something like that ), which provides information about cpu temperature, fan speed etc. It does this by reading SM bus connected devices. RAM happens to have a little ROM on it called an SPD ( serial presence detect ), that connects the the SM bus, whose purpose is to tell the system what its timing requirements are. cpu cool can read this info, and tell you. I found out one of my DIMMS is only PC100, instead of PC133 like I run it at. Its probably a source of some of my system instability. Jon.
