[Tested] ASUS GTX 560 Ti DirectCU II GPU Overclocking Session

Article index:


As you can see, there’s not an absolute overclocking setting but rather per-app settings. You can consider FurMark as a way (BUT not as the unique way) to find a very stable OC setting. And as you will see in an upcoming review, a card can be stable under FurMark but unstable under 3DMark11. The important thing to keep in mind, is that the OC setting must be stable for the set of applications you have selected.

But as I said, FurMark has no equivalent when it comes to torture the VGA cooler or the power circuitry:


And for your favorite game or 3D app, the max GPU clock will be certainly different (ex: 3DMark11: GPU: 1000MHz, VDDC: 1.112V).

{GPU: 1000MHz, VDDC: 1.112V} is ok for 3DMark but not for Unigine Heaven who needs an OC setting of {GPU: 990MHz, VDDC: 1.150V} to be stable.

When we talk about GPU overclocking, the GTX 560 Ti is a real beast, especially ASUS’s GT 560 Ti DC2. The reference GPU is 822MHz and we can run many apps at 1000MHz, putting the GTX 560 Ti ahead of the GTX 470, the HD 6950 and even the GTX 480.

The GTX 560 Ti is stable at 970MHz for the whole set of test applications (even if for some apps, 1000MHz is stable). Then the final OC award is:

ASUS GTX 560 Ti, OC Valided AWARD

The max Vcore available is 1.150V. Can we go further? Can we apply a higher Vcore and maybe find a higher OC setting for FurMark or the other 3D apps? The answer is certainly yes thanks to some modifications in the GTX 560 Ti BIOS. If possible, I will explore this topic as soon as I can for new article on GTX 560 Ti overclocking. Stay tuned!
