GeForce GT 430 overclocking issues

post #1 of 3
Thread Starter 
So I had my GT430 overclocked just fine using MSI AfterBurn with a core clock of 825 MHZ, a memory clock of 900 Mhz, and a shader clock of 1650 MHz, so I started to play GTA4 to test it, and it was running great, so I decided to run the in-game benchmark, and right as it started the screen went black for a second, and my overclock returned to default.

After that happened I went back to the desktop to try and reoverclock it.

so I turned the core clock back up to what I had it at before and clicked apply, and nothing happened. in msi afterburn the slider just moved back to the default position.

I tried the same thing with the memory slider, and the same thing happened.

Im kinda new to overclocking, but ive done it enough to relies something is messed up, and I don't think its user error.

Has this ever happened to any of you guys?

If so some help would be very appreciated.

when the driver crashes like that, you have to reboot the computer. The driver sets the clocks into a "failsafe" state apon re-initializing. The best way ive found to find nice stable clocks is to fire up furmark, let it set in for a little bit, and then start increasing the clocks on the fly. Do the core/shaders first (unlink them), and then do memory. Stop when artifacts show up, or when the card crashes. When either happens, back off about 15mhz, and let furmark cook the card for about 30 minutes.

If it doesnt crash during that time, the clock is good, have fun
