Review: PowerColor Radeon R9 290 PCS+

Overclocking

Speeding this heavy-duty beast up means pushing the clocks higher. We managed a stable 1,10MHz core and 5,660MHz memory, representing increases of 6.7 per cent and 4.8 per cent, respectively.

You don't receive much extra performance by increasing the frequencies, certainly not enough to notice whilst playing games. Power consumption rises to 317W and noise to an intemperate 47.2dB.
