Reference AMD 7950

Overclock Tool
MSI AfterBurner/AMD GraphicsManager (for 1600m)

Stability Test
3dMark FireStrike

What's a good tool to get past clock limits? AMD GraphicsManager ruins the power states (always at full speed). I know it's capable of more than 1200, it's only at 1.1v!

Gigabyte 7970 Windforce O.C. rev 1.0

1150 Core
1500 Ram
+10% power Usage

75 degrees celcius during peak.

It has plenty of room to O.C. and the voltage is unlocked. It can do more if I had it under water but not necessary for my needs.

HIS 7970 with the reference cooler, bought around March 2012.

1.15 volts
20% power usage
1150 Core
1550 Memory

It runs farcry around 76 C with a fairly aggressive fan profile. The memory is definitely topped out, and I think the reference cooler is to blame. I have gotten the core to run Heaven at 1200 with 1.18 volts, but the temps and fan noise aren't worth the extra 4%.

Does lowering the power limit help with temps? Based on Thorin's clocks I could probably step it down few %.
