PowerColor has its own overclocking tool dubbed the Powerup Tuner, which offers basic options and allows users to overclock the GPU, memory or manage fan RPM. We loaded the second BIOS since it offers more aggressive AUTO fan management. We had no trouble upping the memory clock from 1350MHz to 1650MHz (effective 6600MHz). The GPU was keen to cooperate and we easily overclocked it to 1090MHz by using +40 adjustment to the PowerTarget settings.With fans at 100% we did not notice clock speed throttling. After our overclock the system used 100W more power. Battlefield 4 yielded a 6% performance gain.
