Recently, AMD presented the GPU AMD cypress, the last has a good overclocking potential.
Thus, for instance, four cards ASUS radeon HD 5870 with 1 GB memories, installed in one PC in regime 4- way crossFireX, each card was overclocked the frequencies 1035/1290 MHz on the chip and memory respectively. This gave a big enough increase in the productivity relative to the base frequencies (850/1200 MHz).
Four cards showed the result X26332 in the test 3DMark vantage (with extreme profile). In this case, they were cooled by usual cooler each.
For obtaining a higher frequency , the vGPU value was increased to 1,33 v (instead of 1,015 v) in GPUTool. Let us recall also that ASUS itself provided the possibility to increase voltage to 1,4 v , As CPU came out Intel core i7 965 XE @ 4257 MHz and the motherboard was ASUS P6T7 WS superComputer, all components used are standard, without extreme cooling Related Products :
