I installed MS processor driver (latest version) from the MS website. I sat down and after a short while, I noticed the temps were lower than normal. I then raised the fsb a litlle, and the temp didn't move. I got brave and tried to "saturate the I/O bus") and see if that would do it; it did, but no errors or crashes after 1.5 hours (which is the norm). I then set the memory (Samsung PC2700) at CAS 222 1T and ran it at 146mhz FSB x 11 one hour of Unreal Tournament 2003 (UT2k3). No crashes for one hour. I was wondering if anyone has similar experience, or did I originally have a corrupted driver, and this one merely fixed a known bad one?
