Memory VS Core clock. Which one should I overclock?

[,,,,,,,,,,,,,,,,,,,,,,,,,,]

Hey,

I currently own two GTX 760's.

Here is my current clock speeds.

 

 

 

Im just wondering, which one is better to overclock? The core or memory?

Im guessing if I lower the memory back to the default I could raise the core clock a bit more because

the memory would be using less voltage?

 

Thanks.

bump up the Core clock first

 

 

only touch the memory clock later

The core clock is where you get most of the extra performance, the memory clock gives a couple more FPS (Unigine Heaven) in my experience. 

 

ASUS GTX 770, OCed GPU to 1260 MHz and get a 15 FPS boost, memory OCed to 8000 and got 3 more FPS. I'd leave the memory alone, it only creates more heat anyway.

Thanks for the  replies!

I'll do the core clock until my GPU crash's.

I've been using the Furmark GPU stress tester to do my overclocking, is there any other programs I should use?

Heaven, it is more stressful therefor your OC will be more stable.
