[GPU] Overclocking Help! (770 Windforce)

CHarrisMedia · February 20, 2014

Hello all!

I would like to start of by saying, by no means i'm an overclocking freak. I recently got my GTX 770 Winforce (2GB Model) GPU as an upgrade and decided I would like to overclock the card to see what results i could achieve. After watching a few videos (one of which being Linus's titan video) this is what I was able to achieve. If there are any experts in this field, i would love tips / improvements I could achieve to boost the card even further. I'm not too worried about the Voltage however I would like to keep the card below 80C, Fan speed also isn't too much of an issue providing it's reasonable. This is what I currently have:

For some reason, this doesn't change:

I usually leave this like it is above, however this is what happens when i turn on overvoltage.

I could probably go higher however am a little in confident as i'm not used to overclocking whatsoever. Any settings improvements you guys suggest / use I can go ahead and try them out.

Background notes:

CPU: i5 3570K (Not Overclocked)

GPU: GIGABYTE GTX 770 Windforce (2GB)

The room is usually warm (For the UK in winter) however if the room gets too hot, I can cool it down easily.

Operating System: Windows 8.1

Driver Version: 334.89

GPU-Z Info:

Games I usually play:

- Battlefield 4

- Far Cry 3

- Splinter Cell Blacklist
- Arma (Day-Z)

- Call of Duty Ghosts (However I cannot use fraps as it causes confliction with my mouse (Looking up randomly etc) and it does not show my FPS in-game, Also when i use a zoom scope, i notice a frame drop)

- Crysis 3

If anyone can help me with the Call of Duty ghosts issue or if you have any suggestions about overclock i'm currently running, please respond with a comment.

Thanks!

I would go ahead and put the power limit and temperature limit to the max, otherwise you aren't taking advantage of that +12 mV. It will also help with some stability if you overclock further.

I have an EVGA 770 with ACX cooling and it doesn't go above 80C unless something other than the card is not right (e.g. High ambient temps, or a fan not speeding up to compensate). Considering you have a better cooler than I do, it should be even less of a problem for you.

Thanks for the suggestions, I have done what you said. Also, my fan curve is set lower than the temp target, hopefully this will ensure it doesn't get above 80C.
