Overclocking The GeForce GTX 670

EVGA Precision 3.0.2 Overclocking Utility

EVGA has been producing the Precision Overclocking Utility for years and it has been without a doubt one of our favorite tools to overclock video cards since it came out. You can now adjust the power target of the video card and the GPU and Memory clock offsets within a certain range. EVGA Precision X 3.0.2 software makes overclocking easy and that is what we will be using this for this section of the review. We are also using the new GeForce GTX 670 skin that EVGA made for this card!

EVGA Precision X v3.0.2 lets you increase the power target to 122%, the GPU clock offset to 549MHz and the Memory clock offset to 1000MHz. We were told by EVGA that they are seeing overclocks similar to the GeForce GTX 680 and that we can expect to be running boost speeds of around 1200MHz after overclocking.

After spending some time with the EVGA GeForce GTX 670 SC 2GB we found that we were able to reach +130MHz on the core and +25MHz on the memory. This is a great overclock on the GPU core from what we can tell as the core was hitting 1280MHz in games and the memory was hitting 6264MHz!

Here is a GPU-Z screen shot of our highest stable overclock. We checked power consumption numbers at load and in Battlefield 3 we were using exactly 30 Watts more power at the wall with this overclock (331W versus 361W). Not every game pulls the same amount of power though and on Metro 2033 the difference was observed at just 11 Watts (322W versus 333W)

EVGA GeForce GTX 670 SC at 1097MHz core and 6264MHz memory:

Radeon HD 7770 Overclocked

We tried out this overclock with Futuremark 3DMark 11 on the performance preset and saw the score go from P8745 on a bone stock NVIDIA GeForce GTX 670 to P10065 on the EVGA GeForce GTX 670 Superclocked with the highest overclock that we could get stable. This is a solid 15% or 1320 3DMark point increase from the card’s stock settings. These cards are very overclocking friendly as you can see from our results here.
