Overclocking

GPU overclocking is available within the "Arc Control" control panel software provided by Intel. At this time memory overclocking isn't listed, but I think they'll add this capability eventually. Just like other parts of the driver, Arc Control is quite buggy and completely unrefined.

For example, the "percentage" GPU frequency overclock really isn't a percentage at all. I ran "+31%", which gave me clocks of 2696 MHz or +10%. The voltage slider allows a crazy up to "0.725 V", and doesn't do anything in reality. Memory OC missing as mentioned before, the power limiter can be adjusted, but the numbers don't work to exactly limit the power draw, it's just a rough estimate, and it seems to be a GPU-only measurement, the actual card draws much more power as revealed by our own testing.

Overclocked Performance

Using these clock frequencies, we ran a quick test of Unigine Heaven to evaluate the gains from overclocking.


Actual 3D performance gained from overclocking is 5.0%.
