6990 Overclock on air - Advice Appreciated :)

post #1 of 3
Thread Starter 
G'day all!

I have just recently built a new rig and as I have not been in the scene for a good while I have no idea what good clock speeds are for gaming on the 6990. I could spend all day testing myself but any help advice/best practices would be greatly appreciated.

Thanks guys!

I would suggest simply small increments in clock speeds and then testing with Unigine Heaven.

If it crashes or causes artifacts, time to bump up the voltages in small increments as well until you reach something (clock, voltage, temperature) that you feel comfortable with.

Switch AUSUM BIOS to position #1 will set the stock core/memory to 880/1250 MHz and default voltage to 1.175v. Without overvolting 930-940/1400 MHz is pretty easy and adjust PowerSetting +? % to maintain stable OC.

That's as far as I would go on air, prevailing fullload temperature below 75°C.
