Overclocking
With a similar design to the GTX 660 Ti, but with increases in TDP and the memory controller I wasn’t all that sure what to expect when it came to overclocking the GTX 760. On the GPU Core Clock side of things I started off with a 200Mhz offset expecting it to fail and to set my testing range but surprisingly it passed. I bumped up higher to 300Mhz and it failed and worked my way back down to find out that the 200Mhz was very close to my max overclock. My best ended up being 215Mhz Offset giving me a GPU clock speed of 1372 while in our 3dmark 11 test 2 benchmark.
On the memory side of things I wasn’t about to waist too much time, knowing that the GTX 770 did so well with a similar memory controller I started at 300Mhz offset and went all the way to 600Mhz before it failed on me at both 750Mhz and 650Mhz. The 600Mhz memory clock speed offset ended up being the sweet spot that didn’t give me any artifacts while testing as well. The overall memory speed was 3602Mhz or 7204Mhz, very impressive! I was able to combine the two results without any issues as well as you can see on the last line in my testing in the table below. Overall I was very happy with the overclock possible with the GTX 760, especially on the memory side.
