Hi,
I have two EVGA SC ACX 2.0 GTX 970s. One card was boosted to 1405 MHz stock, while the other was overclocked to 63 MHz above that to avoid bottlenecks. Both memory clocks are comfortably around +400 MHz up to 1951 MHz (though I’m not sure what that means). Based on my research, the system should handle about 790 W load with an 850 W PSU. I’m thinking about upgrading to a 1000 W power supply for more headroom in future overclocking attempts.

I’m having issues because while benchmarking and gaming without overheating or instability, my driver crashes after 5–10 minutes of playing Rocket League. I don’t seem to be hitting the base clock of 1165 MHz, so it’s not the core issue. I’m trying to figure out if I’m drawing too much power from my PSU at high loads, causing this problem, or if the memory clocks are too high.

Best,
Jake

What benchmarking software are you employing? I opted for 3dMark post-overclocking and Uningine Heaven to identify the optimal performance level.
