Shipping with a fitted liquid cooling
solution from EK Water Blocks, PowerColor has been rather coy with ramping up
clock speeds. These remain true to a reference HD 6990 - coming in at 830MHz and
5,000MHz effective, switching to 880MHz and the same 5,000MHz effective - for
the GPU and GDDR5 respectively - when using, what we've lovingly called, the Switch of Awesomeness.
As for the liquid cooling solution,
PowerColor tells us that even under full load, its LCS HD6990 package
demonstrates a thermal advantage of up to 30 per cent over a reference-based
solution. This, it is claimed, should increase overclocking headroom and
potential - if dabbling in the arts is your penchant. A single-slot form factor
goes against the grain and the manufacturer adds, that the use of a Volterra VRM
solution adds to stability and overclocking prowess as well.
