With manual overclocking, maximum overclock of our sample is 1860 MHz on the memory (6% overclock), which is limited by the adjustment range in Wattman. I suspect the chips could go even higher, but for some reason, AMD chooses to artificially limit overclocking potential of their cards. GPU overclocking also maxed out the slider range; it seems the overclocking limits were not extended with the new BIOS.
Maximum stable overclock was 1820 MHz Boost, which increases average GPU clock from 1709 MHz to 1763/1764 MHz (3% overclock).

Overclocked PerformanceUsing these clock frequencies, we ran a quick test of Unigine Heaven to evaluate the gains from overclocking.
Actual 3D performance gained from overclocking is 9.7% for the Gaming X and 4.1% for the Gaming Z.
