GTX 480 Overclocking
As we mentioned overclocking was done with MSI Afterburner; speaking to MSI they told us that a Core Voltage of 1100 was safe; so I went to 1113 because I live life on the edge.
At first I did my overclocking with the fan left on AUTO; the problem is I had Vantage crashing at core clocks lower than what I ended up with. It seemed that the fan wasn't speeding up enough to keep the video card cool enough and in turn Vantage would freeze up by the second test. By moving to 100% we got through Vantage no problems; so we thought we would see if we could go higher again and we ended up with about another 15MHz.
As for the final overclock and how it compares to the reference one; 841MHz on the core which is way up from the stock 701MHz. The Shader clock has of course increased; that's gone from 1401MHz to 1682MHz.
While the memory might not get any love from the voltage adjustment we did manage to increase that from 3696MHz QDR to a very yummy 4200MHz QDR.
That's some serious clocks; hopefully it brings with it some serious performance!
