NVIDIA GeForce GTX 760 Mainstream GPU Review

Overclocking the GeForce GTX 760

We also spent a little time overclocking the GeForce GTX 760 to see what kind of additional frequency headroom it had left under its hood. For these tests, we used the latest edition of EVGA's Precision X GPU tweaking utility, which is designed to work with NVIDIA's GeForce GTX 700 series products.

Overclocking a Kepler-based GeForce GTX series graphics card requires a bit more tweaking then previous-gen products, due to all of the new options available and the complexities associated with GPU Boost 2.0. Sometimes, you’ll find that increasing a particular voltage or frequency may appear to function properly, when in fact performance decreases due to errors or throttling. You may also find that the actual GPU Boost clock may travel above or below the designated offset value when the power and/or temperature targets are also increased.

We did a few things when experimenting with overclocked speeds on the GTX 770. First we tried the most basic option available--we simply changed the temperature target from the default 80'C and increased it to 94'C to see what kind of impact it would have on performance. Then, to push things much further, we increased the power and temperature targets to 115% and 94'C, respectively, and also increased the GPU and Memory clock offsets and ran a few tests. Unfortunately, due to time constraints, we didn't overclock both of the GeForce GTX 760 cards we had on hand, and focused solely on EVGA's SC w/ ACX model.

Ultimately, we were able to take the EVGA GeForce GTX 760 SC w/ ACX cooling all the way up to a 1333MHz GPU clock with 1548MHz memory (6192MHz effective). Those are some major increases in frequency over the stock 1033MHz (GPU) and 6088MHz (memory) frequencies called for in NVIDIA's spec.
