AMD Overdrive?

Has anyone used AMD overdrive? I'm trying to overclock my GPU and would this work just fine?

Because I don't want to install afterburner if I don't have to

Hmm ok, but I'm pretty sure that as long as you stay at stock volts, you should be fine right? Because overdrive keeps my 7850 at stock volts, and the fartherst I can go is 1050/1450 vs 860/1200

I've used AMD overdrive to OC my 5770 and I must say that the auto overclocking feature plain sucks. Even after it has tested the overclock that it recommends, I see frequent game crashes and "The display driver stopped responding" errors.

I find MSI Afterburner to be WAY WAY better than AMD Overdrive in terms of OC'ing. You can log your temperatures and find out exactly how hot your PC runs when you're gaming, set custom fan profiles to keep your GPU at temps that you think are acceptable. And if you're planning on going a little further, a little .ini tweak allows you to change voltages and unlocks OC'ing abilities to allow you to push your card even further (I would recommend NOT to meddle with these things if you do not know what you're doing. You could end up SERIOUSLY damaging your hardware).

My recommendation would be to install MSI Afterburner, and use GPUTool to stress test your card. Increase the core clock first in increments of 10Mhz and stress test your card with GPUTool for 1 minute after each increase, till your card gives you a "Display driver has stopped working" error, or till it shows other signs of instability such as artifacts in GPUTool. Then decrease the core clock by 5Mhz till the card is stable again (Run GPUTool for a few minutes this time). This will give you your stable core clock OC. Then do the same with the memory clock (with core clock reset to normal while you do it). When you've found the maximum core and memory clocks and want to apply them, you may have to reduce one or both of them slightly to get your card stable.

This is what I do. Hope I helped.

I've OC'ed my 7850 using OverDrive (I think its just because the 7850 is so OC'able) to 1050/1450, which is the max on stock volts.

Does Afterburner allow you to change your voltage to increase it further past the max clocks on stock volts?

Cool, that's a good OC. 7850 IS a good OC'er. Yes, Afterburner does allow you to increase it further past the max clocks if you enable UNOFFICIAL overclocking. You already know this but I'll say it again, be careful when tweaking the voltages and such, and remember to take SMALL steps increasing the voltage ( I MEAN TINY). :) If you choose to go the unofficial OC'ing route, then you most probably will have to increase your voltage, as the stock voltage probably won't support much more OC'ing than you've already achieved (I may be wrong, since I don't one a 7850, but that's how it is with my 5770)
