Help Overclocking EVGA GTX 660Ti

[GrayHD]

So I have a EVGA GTX 660Ti and I've overclocked it to +140MHz GPU Offset, and +500MHz MEM Offset. It runs at about 65 degrees during a stress test. I'm not complaining because this seems really good compared to other people's over clocks but when I run benchmarks, other people's systems seem to do almost better than mine. I get about a 900 score in Unigine Heaven 4.0 Benchmark with an average fps of 37 fps. Not really sure what's happening but I'm just curious why this is running at such a high overclock compared to most people and why it isn't preforming as well as I think it should.

Also, should I overclock it more, or just leave it as is?

PC Specs:

CPU: i7-2600k @ 5.0GHz
RAM: 16GB Corsair Vengeance
Motherboard: Asus Sabertooth Z77
GPU: EVGA GTX 660Ti 2GB
OS: Windows 7

At 65 degrees my fan is running at around 75%.

The card is running at 1.175V when on full load.

I have my CPU water cooled and my Graphics card is air cooled by the stock cooler.

If you have any other questions just ask and I will answer.

So I changed my GPU Offset to +120MHz after running Heaven 4.0 and it crashing. Everything runs fine now and I'm getting higher benchmarks than before when I had a higher GPU Clock. I guess I just didn't have a stable OC so my GPU was down clocking. Basically, moral of the story... make sure your overclocks are stable before jumping to conclusions.

Hi and welcome to Tom's forum.

You found the answer by yourself, overclock and higher clocks not always means better performance in GPUs. In thsi case, you have to had a good clocks combination between core clock and memory clock, the most important is the memory clock but start 1st with the core.

Create a fan profile to keep your GPU the most coolest as possible and even if you GPU can pass Heaven, I suggest you test too with 3DMark or even games.

Thanks for the tips, and I tested it with 3DMark as well after I got a stable overclock. I will definitely test some games on it though and make sure they all run fine.

Excellent, let us know the results.

Excellent, let us know the results.

Been playing Titanfall Beta recently and other games and everything is running well. It passed 3DMark11 and Heaven 4.0 with good scores (around 9500 for 3DMark11 and 1030 for Heaven 4.0). So everything seems to be going perfectly so far.
