Overclocking sapphire hd 7770 vapor-x oc edition????

[Born.9inety4our]

i have this card with a default clock of 1100Mhz and default memory clock of 1300Mhz
max clock according to the AMD overdrive is 1500Mhz and 1625Mhz respectively

i want to over clock my gpu to achieve the best performance but i don't think that it will be stable if i push the clocks to their limit(max). im new to overclocking so i need your help, i just wanna try overclocking )

what do you think is the highest stable settings of the core and memory clock of this card? )

Take it slowly.
Increase core clock by 10MHz and run afterburner. Keep eyes on temps and artifact count (it has one right?). Try to stay under 80-85'C. You can set fans to 100% but it is not needed.
If you overclock too much and card crashes it will revert last change (or back to default) in clocks speed. It is not that easy to burn hardware novadays. As long as you do not play with voltage you are safe. And if you want to adjust voltage do it very slow. And stress test after each change to see if your card is not overheating.

PS. That card looks nice!

thanks for your reply, it helps me a lot ) yeah i was also amazed with this card..

EDIT: i successfully overclocked it to 1140MHz for core clock and 1340MHz for its memory clock
max temp is 40'C ,,, is it good? benchmarks crashes if add 5MHz more..


how about my i3-2120? can i overclock it?

Good luck with overclocking. I have a Gigabyte HD7770 that is factory overclocked to 1050, but will not overclock at all past that, even given the limits of the CCC. The card works well for the price and power usage, but I am really disappointed with the overclocking, since I thought there was a lot of headroom.

Gigabyte HD7770 looks cheap and I don't think you can increase core voltage. Make sure you have good quality power supply.

Nice. Can you increase core voltage?

Nice. Can you increase core voltage?

yes, up to 50% more
