HD 7970 DCUII Overclocking
The ASUS HD 7970 DirectCU II TOP has already been proven to have some amazing features for overclocking but even on the software side they give you some love as well.
ASUS has been refining the GPU Tweak software for quite some time and with the version you see here there are many cool features you can utilize to push the performance to new heights. For starters things are easily adjustable via sliders but that’s kind of common practice so we will call it par for the course. However ASUS includes an option at the top to disable 2D mode directly in the interface so that some of the issues we have seen in the past where the driver may drop to 2D mode for odd reasons during a gaming session would be removed, of course this does cause a bit more power consumption so we would say use this function on a as needed basis.
One area I can personally see a benefit to disabling the 2D mode is during benchmark runs. If benchmarking your not worrying about power saving or anything like that and you just want the maximum performance, well that is what you get as the card stays clocked up so no unnecessary delays or stutters as the driver hunts for the correct current power state and clock to put the card at which could cause a small drop in an otherwise impressive benchmark score.
Also included in the software is a Special ROG Edition GPUZ which can easily be accessed via the ROG GPU Tweak software control panel.
We did not get time to give the card a full thrashing in the overclock department but we can say that with the GPU hotwire and bencher friendly components we see no reason why this card should not blow away some competition. We did however get to put it through its paces in some gaming benchmarks so lets see what you can expect if you slap one or even better two of these in your gaming rig!
