View Full Version : Overclocked CPU kills 6800U stability??

I found that my overclocked P4 will lock up mid game with my PNY 6800U with any driverset newer than 61.32. And yet the card itself is not overclocked. However if I use 61.32 or earlier I can run my 3.2 processor at 3.6 with not problems. I wonder what gives. Anybody having simliar problems?

The cpu asks for more watts when it's overclocked your PSU could just not be providing enough power after you overclock it.

Good though, but I do have an I antec 550W tru power which I hope would give me enough juice.

Have you tried adjusting the voltages any just to see if that helps?

Edit: For example, with my XP 2800+ I can overclock it pretty easily and not have to do anything extra for stability. If I overclock the XP 3000+ very much at all, I end up having to play with the voltages to get things stable. I thought this was a result of the AIW 9800 Pro I had in the system earlier (since it just seemed extra sensitive to overclocking) but once I put my 5900U in that system, things are pretty much the same. I have to adjust the AGP voltage for things to be stable whenever I overclock the CPU.

Ok, i dont want to ask a dumb question but is your AGP/PCI lock on?

thats actually not a dumb question at all.. i overlcoked my agp slot up to 90 mhz and it was crap... anything above default and it was all jacked up

Yea its locked. Tried tweaking voltages.
