HISís iTurbo Software / Overclocking Results
HISís iTurbo Software
Like many other manufacturers, HIS has decided to get into the overclocking software game. Their new iTurbo is a reasonably well rounded and straightforward application which grants access to most fine-grain clock speed and voltage controls. Its layout is clean and easy to understand so it wonít present a daunting challenge for first-time users.
There are five separate panels covering system information, fan speeds (where custom profiles can be set) and general application settings but the one youíll spend the most time in is Overclock. In this section, iTurbo allows for complete control over the graphics cardís memory and core clocks as well as their associated voltages. Naturally, a Power Limit slider is included as well.
On all of the previous pages, we have seen how the IceQ X≤ cards perform when they are overclocked at their default voltage (alongside a Power Limit of +20%) but there was a whole lot more left in the tank. The core and memory voltage of both cards was increased by 10%, a ďsafeĒ setting that shouldnít impede long-term ASIC life.
The final results are below (core/mem):
HD 7970 IceQ X≤: 1322MHz / 6888MHz
HD 7950 IceQ X≤: 1125MHz / 5804MHz
