Overclocking
With an enhanced power target and no added voltage, we were able to increase the base/boost core speed to 1,652/1,766MHz and memory to an effective 12,008MHz. Actual in-game core speed was 2,050MHz.
Gears of War 4 scaling is very good, most likely due to the higher memory clock. The other two benchmarks show more modest increases. Bear in mind that system power consumption jumps through the 400W barrier once the card is overclocked.
