Vid card problems when CPU overclocked

Drak55 · Aug 19, 2002

well as you see I have the CPU unlocked and at 2gigs when I play a game out of the blue the game stops and I'm back at my desktop screen if I lower the clocking to about 1926 it wont do that anyone have any idea why my vid card is doing this again it only hapends when playing a game never when just urfing on doing other thing on my comp.

Seems to me you may need more voltage on the ram due to the fact you are running 1 gig of it and probably at a very high FSB. Is your video card overclocked? Sometimes video card may not like high AGP Bus + being overclocked at the same time.

Try playing around with timings and see if that helps and trying different drivers.

How are you determining system stablity? I recommend Prime95 Torture Tets.

I wonder if running your AGP Bus under spec would be more of a problem than running it above spec. Try this as a test; 166x12 = 1920. See if you have any problems then. That is perfect spec with the 1/5 divider kicking in. Try the video and sound section for the best drivers avaliable for your card. Again use Prime95 to test your stablity, and make sure your ram isn't creating a problem.

if I run it at

155
12.5x
1.850v
it gives me 1932 the vid card gives me no problem at that speed its only at 2000 that it clicks off any game I play I could play for an hr and then it just clicks off the game and I'm on my desktop.

What is your 5v rail at load? You need to find your rails at load by using Prime95 which I've mentioned. Those GeForces 4 will eat up power from the 3.3v and 5v and if your lines are too low and fluctuate that can be a problem.
