Overclocking

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 Kombustor for stability testing as they’ll drawing 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.

With that out of the way, we settled in for some overclocking of the core and memory clocks and achieved the following result:
