Sapphire Radeon HD7770 GHz edition overclocking

post #1 of 3
Thread Starter 
I've used the Sapphire Trixx software to overclock my older Sapphire Radeon HD7770 GHz edition 1GB card and I seem to be getting about a 30% performance boost from stock settings.

I have not used this setting long-term to ensure stability, but it seems fine so far.

I'm just wondering if anyone else has tweaked the settings and gotten better performance or have any suggestions on what I might be able to do to improve performance.

GPU clock 1245 MHz
Memory clock : 1250 MHz
Voltage adjustment : 0%
Fan Speed: Auto

3DMark11 benchmark score: 5102

3D Benchmark with stock settings: 3863

I found a new setting that works stably, but uses increased voltage, so I use it sparingly.

GPU clock : 1260
memory clock: 1380
power limit +8%
fan speed: Auto or Manual
3D mark score: 5351

Wow looks good. My old 7770 had no voltage modification, nor bios so all I could get to was 1100 but it was still a pretty capable 720p GPU
