Ummm...Can't OC a 570..Help?

post #1 of 3
Thread Starter 
Well, when I set core clock to 750mhz in Afterburner and run 3DMark11, it just crashes a minute into it.

Set core speed to default and it would run fine.

Voltage is stock @ 0.95
Core and shader clocks are linked.
Drivers are latest.

745mhz is the max I can get with this???

Am I missing anything?

If you want a stable overclock you will have to increase voltage. Though my 570 went to 850 on stock volts 3dmark and gaming stable for months, I've only just recently had to increase voltage to keep it stable but thats another matter. 750 seems a bit low.

Be aware that reference 570s have some issue with their VRMs and applying more voltage may fry your card.

I got the MSI 570 GTX non factory OC card, I guess thats a reference card. Thinking of going back to 6950 CF


UPDATE: Well, I finally got everything working, I had to up the voltage and also uncheck "Force Constant Voltage" in Afterburner. Up to 800 Mhz @ 0.985 volt without a problem.
