Overclocking
Overclocking an already overclocked card can sometimes be a little interesting. For starters there is less overhead because the card is already using some of the overclocking ability that you would normally be getting. Having said that, pre-overclocked cards like the MSI GTX 780 Gaming normally also come with amazing cooling meaning heat is rarely the issue that will hold you back, short of extreme cooling designs of course.
This time around I jumped into overclocking the GPU with a healthy 200 MHz offset but if you look at the resulting speeds it didn’t show any improvement going from 200 to 265, oddly enough though my FPS results did jump. I assumed that I had capped out at 1032 MHz but it is possible considering the faster FPS that my resulting speed may be off for some reason. Anyhow, I wasn’t able to edge any more of an offset on the GPU, so I moved onto the memory overclock. As you can see I was able to bump the memory performance up multiple times before I ran into issues at a memory offset of 500 Mhz. Even then it wasn’t a hard crash, so with fine tuning I could have gotten something very close to 500 Mhz. Having said that, I went for it again on my combined tests running an GPU offset of 260 and memory at 500 Mhz. Surprisingly I didn’t experience the artifacts that I saw on my memory testing.
All in all, the MSI GTX 780 Gaming overclocked well and I am willing to bet its additional cooling played a big part in that. If I was able to toss more power at the card I bet it is capable of a lot more.
