Overclocking trouble

I just received my GTX 280 today from EVGA, and I put it in, and the O.S. booted just fine, but before long at all I had a BSOD. After the reboot Windows said that these files were causing the problem:

C:\Windows\Minidump\Mini100808-01.dmp
C:\Windows\Temp\WER-42962-0.sysdata.xml
C:\Windows\Temp\WERE55E.tmp.version.txt

I thought that maybe it was my overclock, I had my Q6600 running at 3.2GHz (400x8) with a 1:1 divider on my 4GB DDR2 800 RAM (5-5-5-15). Vcore was at 1.4500, and DDR2, FSB, and MCH voltages were all overvolted by .1V (All virtualization and unecessary things disabled, PCI-E frequency at 100MHz). I reset bios to optimized default, at which everything was stable, and redid the overclock. I ended up getting the same BSOD. These are the same settings that worked for weeks, all tested in Prime95.

Now I'm redoing the overclock again, but I'd really like to know why these setting (that worked before) won't work now. Thanks!
 
A quick update: I can't get it above 3.0GHz (375x8). I even tried raising the Vcore from 1.3625 to 1.4625; it's looking like it's not voltage. Like I said before, my settings are no different now than they were before I installed the GTX.
 
u installed a 280GTX and u got a BSOD? what was the BSOD error? was it nv4.disp?

if u must have the same OC as before.. try resetting the CMOS
 
I've had to do that before, but then it was an emergency. Is there a big risk to pulling the battery off the board? I won't have to flash to the latest version again will I?
 
Yeah, now I'm quite sure it was not the video card. The bsods didn't mention anything about display drivers. I'm going to go ahead and clear the CMOS and try again.

Edit: Looks like clearing the CMOS did the trick. I use CoreTemp, and I've noticed that core 0 is consistently warmer than the other others, usually by about five or six degrees. The other three are always within a degree or two of each other. Do I need to re-seat my HSF or is this normal?
