i have had my Gtx 570 for 3 monthes now and it has been all fine for the past 3 months but recently it has been horrible. whenever i change the voltage about after 20 minutes of playing it resets causing my computer to crash because of my high overclocking. can someone tell me why this is happening
As GPUs and CPUS age, they need more voltage to keep them stable. You can either reduce clock or increase voltage. 911 is not high at all so I would try increasing voltage as long the the temps were under control.
