all depends on what currency your mining Huh

for example in BTC;

in AF make sure you have the "sync similar gpu option" UNCHECKED

keep the voltage at stock, push powertune all the way up, drop the vram and far as you can
push the core clock in increments of 5 and test for 12-24 hours. if the gpu is stable continue to push addition 5 and repeat until your GPU crashes then you know your cards clock. you can then start to drop the voltage little by little testing yet again 12-24 hours until your card crashs

OC testing is rigorous and time consuming. usually requires a lot of babysitting your rigs. but once you find the sweet spot your rig is pretty much automated

I Merge mine on the guild. ( BTC & NMC ) cgminer 3.3.1

"in AF make sure you have the "sync similar gpu option" UNCHECKED" - I take this as a referral to Afterburner?

"keep the voltage at stock, push powertune all the way up, drop the vram and far as you can

Cgminer is great and easy. There is a GPU management button, choose the device, and you can alter clock and mem speeds, as well as fan settings. Alarmingly easy!
