So I decided to overclock my gpu (sapphire radeon hd 7870 ghz edition). I overclocked using the catalyst suite, with its integrated overdrive feature.
Here's some info that might help you
I didn't use any voltage wteaking (i wanted to overclock without getting risky). I cranked up the speed by 50mhz packs.
The Furmark settings were 1280x1024 resolution, 8x MSAA, Dynamic Camera and Post FX at 1 minute duration. Also not that I did not see ANY artifacts.
#Stock core speed: 1000mhz
Furmark scorre:1817
Avarage fps: 30
Max: 33 Min: 27
#Setting power limit to +20%
Core speed: 1000mhz
Furmark:1819
Avarage fps: 30
Max: 33 Min: 27
#Core Speed: 1050mhz
Furmark score:1861
Avarage fps: 31
Max: 34 Min: 28
#Core Speed: 1100mhz
Furmark score:1888
Avarage fps: 31
Max: 36 Min: 28
#Core Speed: 1150mhz
Furmark score:1909
Avarage fps: 31
Max: 34 Min: 29
What concers me is that there is not that much of a perfomance boost for stock+150mhz, especially as far as the fps are concerned. The cpu is not a bottleneck, its utilization throughout the benchmark was about 9%-11%
What could be the problem or what should i try doing? Any tips are appreciated and i can provide further info as well as screenshots.
UPDATE
After I cranked the memory speed up I got scores as high as 2050. So the vram must be a bottleneck.
