Underclock on 6800GT

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.
 
I have had some stability problems in games I have been trying to figure out, but haven't tried underclocking it. With the NV Silencer5 Rev2 I get about 40C idle at 425/1100, 55C load (after a few hours). I'll try underclock mine and see if I have the same problems, but it's got an aftermarket cooler on it so I doubt we'll see the same results.

You didn't change the 2D frequency in the drivers instead of the 3D one did you?

I changed both 2D & 3D, actually. My instability problem was happening during general Windows desktop use [web surfing, music management, etc].
 
What drivers are you using?
There was a bug in nvidia drivers for ages that gave dodgy temp readings if you o/c it.
