Otherwise what good is ECC? If it doesn't tell you that something is wrong, then it is useless for detection of problems, no? The information i have found indicates that these errors are stored in the configuration registers of the memory controllers. Unfortunately, i have been unable to get confirmation from intel on this subject. Is there any way to get to these registers from within freebsd?
