Doing some testing to try to find what's been causing instability in my system [see my thread], so I did a modest underclock on my 6800GT. Dropped it down to 335 Core / 800 Memory. Before I did this, the card was idling at about 45C CPU / 35C Ambient, now it's idling at 66C CPU / 47C Ambient. Just curious if anyone else has had this happen... seems strange that an underclock would make this happen. As it turns out, however, the system is running much much better [lost some 3DMarks, obviously... but not having crashing problem]. Odd.
