No need mod bios or pencil mod, there is another way to increase the voltage

<Feature name="CoreVoltageTarget_0">
<Property name="Want_0" value="1046" />
<Property name="Want_1" value="1046" />
<Property name="Want_2" value="1200" />

Change the 'want_2' value to 1200. I dont wanna be held responsible if you did something wrong though so do it at your own risk

Here's my oc


750 core gives me some random artifacts though and my mem is a bit of a chump.. cant oc very high on mem

All using ati tray tools.. spoken too soon, no artifacts at 740 but cant even start crysis benchmark
730 crashed when half-way benching crysis. 720 is stable though

Funny that memory at 1100 is fine.. nothing abnormal yet

Here are some figures



Run #1- DX9 1024x768 AA=16xQ, 32 bit test, Quality: ~~ Overall Average FPS: 34.095
720/1050

Run #1- DX9 1024x768 AA=16xQ, 32 bit test, Quality: ~~ Overall Average FPS: 34.58
720/1100

Run #1- DX9 1024x768 AA=16xQ, 32 bit test, Quality: ~~ Overall Average FPS: 33.47
Default

As you can see, improvement is marginal at best
