(Or, if you just want to be super-safe, add 100 mhz to core clock and memory clock, with manual fan speed 50%+) If your temperature is getting too high, adjust the fan speed accordingly. My overclocked 7870 stays in the 60s under full load with 70% fan speed. GPUs 'can' handle even higher, though I would recommend to keep it in the 70s or below. With memory overclocking you will notice some artifacts in games if it becomes too high.Īs far as temperatures go, anything below 80c will cause no damage whatsoever.
Restart the computer and tone it back a bit. You will get to a point where you crash, but your GPU will be perfectly fine. You can probably add 100 mhz to the core clock/memory clock with no issues, and from there if you want extra, increase in small increments (about 25 mhz). First set your fan speed to 70% to be on the safe side and keep your GPU cool throughout the overclocking process. Overclocking is extremely safe if you're not tampering with voltages. I have a ATI Radeon HD 4800 series if that's what you are asking.
