GFX Card- Asus Geforce GTX780 DirectCU II OC 3G
SSD- Samsung 840 PRO SERIES 256GB
HDD- WD 2TB Caviar Black 7200rpm

oh ok cool, I have that also installed, but could not figure it out.

I used GPU Tweak and used the numbers from Linus Tech Tips.

Do you think you can do better?

Well all I can say is your gpu will do what it can do. Nvidia has locked the voltage so you can't adjust it. The voltage and overclock is controlled by the temperature. Once my 680's hit 70-75c they start downclocking automatically. There is nothing you can do about this it is how they are designed to work. I think you could squeeze more out of your gpu.

ok what would I have to adjust to get a bit more?

I get better performance just using a custom fan profile with a more aggressive curve than OC'n my graphics cards.

OC'n introduces instability after even a small OC.

Keeping them cool ensures a boost clock all the time.

How I do it is I overclock my gpu's while playing a game so, you could fire up battlefield 4 and gpu tweak or precision x. alt+tab out of the game and raise the gpu core first by 10 mhz then play for a bit. if it is ok alt+tab out again and raise the gpu core 10 MHz again and play some more. Don't forget to hit apply every time. Keep doing that until you get a freeze then back it down 10 mhz. Once you find your max gpu core overclock do the same thing with the gpu memory overclock. Only instead of getting a freeze you will get artifacts like flashing dots and triangles. Once you get artifacting, back down the gpu memory until it stops artifacting. That's pretty much it.

As r0wnin said setting a fan curve is a good idea. I set mine so that when the gpu temp hits 70c my fans are running full throttle.

ok cool, thanks 🐵

Oh and after moving Real Bench to my SSD, this is the score I got.

Sorry to hijack, just a quick question.

Is it recommended to change the Vcore setting to adaptive from manual once you've found a stable overclock?

You can if you want if that is how you want your pc to run.
