So now it's time to see how far we can push this card before it gives out on us. I started out small going for an overclock of 850 MHz on the core as always and I left the memory at its stock 1100. I had no problems, so I decided to push a little further and I took it up to 927 MHz and I left the memory at 1100 MHz just to be safe. Again, I had no problems. So, then I decided to see if I could get over 1 GHz. As you can see from the screen shot below, I did. I was able to reach 1010 MHz on the core and 1193 MHz on the memory with the voltage bumped up to 1.174 Volts. I tried the memory at 1200 but it wouldn't do it even with a little more voltage.
For all of the overclocking I used the Sapphire Trixx utility because of its ability to change the core voltage of the GPU. The ability to do this gives us the advantage of higher clocks that just can't be reached in the Catalyst Control Center.
I ran 3DMark 11 on its extreme preset once again to see what the difference would be with an overclock that was over the 1 GHz limit. As you can see there was quite a noticeable difference from its stock setting of 820 MHz 3DMark 11 Score of 1169: a difference of 221 3DMarks, to be exact. To test the stability of the overclocks at each interval I ran the Furmark Benchmark at 1680x1050 resolution for one minute. If it crashed I threw it out, but if it passed I kept it.
With a higher performance overclock of 23% on the core and 8% on the memory came a thermal price to pay. Yes, I must say that the card does run hotter. At idle the temperature went up to 39C with the fan on auto speed and the during a full load test in Furmark it reached 67C in just a one minute test.
