MSI GTX 560 Twin Frozr II 1GB
A couple critical notes before we proceed: as always, mileage will vary when overclocking, so be vigilant in monitoring temperatures and be sure to always test for stability after each incremental change. We recommend FurMark or MSI Kombustor for stability testing as they’ll draw more power and cause higher temperatures than your favourite game or 3DMark benchmark, so it is a worst-case scenario. Otherwise, run 3DMark Vantage or OCCT and see if it can pass a few looped tests for stability, but be sure to log and monitor the resulting temperatures.
We then settled in for some overclocking of the core and memory clocks and achieved the following result:
The GTX 560 topped out with a final stable overclock of 985MHz Core and 1175MHz Memory, for an very respectable 13% over initial clocks on the core, and 15% on the memory.
We did manage to squeak past the 1GHz mark on the core, though it did require a considerable bump in the fan speed, so there is more in the tank here if you’re willing to put up with the noise.
