Overclocking my GPU

post #1 of 14
Thread Starter 
Heya, i got an HD 5750, and i was wondering if it was worth overclocking. Or, of course its worth it, but would it be safe to overclock it from the default at 740MHz to like 850MHz? Or is it too risky? (I got an AMD Phenom II X4 955 BE (Deneb) Processor)

(sorry i don't have my system info in yet. Can't really figure out how to find ALL of my system components. )

That might be too much. try 800 first with default voltage. Than run 3dmark11 or furmark. If it crashes than up voltage. by like 20-25. Each card is different.

Well, wouldnt it be smartest to just let AMD Overdrive decide whats the best overclocking settings, compared to my system?

Get MSI After Burner! Unlock voltage and go from there. Mine is 900mhz and I got it up to 1006 which is about 12% percent increase. Thats about the norm. 740- to 850 is about 15% which might really be pushing it. Start out modest (like 60-75) and than up the volts a bit untill its stable.

This math is confusing. Is the 1006 the RAM speed (12% over stock), or what the GPU core actually runs? If it's the core, that's a 35.9% overclock. I thought RAM speed was automatically higher, around 1150 Mhz as stock.


Willi, voltage is not controllable through CCC. Afterburner needs to be installed, and settings need to be changed in it (a tick box to allow voltage adjustment) to change the voltage. Keep in mind this will increase heat output, and if set too high, can damage the card. Try mild overclocks to start with, leaving the voltage alone. After you're comfortable with that, and have found a stable limit, try adjusting the voltage higher, and overclock more. Watch temperatures closely.

I believe I mentioned above to keep watching them. Granted, I have no first-hand experience with the 5750, but did have a 5770. Without touching voltage, temps were usually fine, in the 60s under load. I think 80C is even a tad warm, although that's possibly personal taste.
