how far could you overclock the hd 7770 with the stock fan and still have stability, and what kind of fan do you buy for overclocking a gpu as i have never done it.

The 7770's should be able to hit between 1100 - 1250 on the core and 1300 - 1550 on the memory on stock coolers.

It honestly comes down to how good your specific card is. Mine is currently running at 1225 core and 1535 memory on the stock cooler and temps never exceed 65C.

Hi. i have the msi r7770, and i OC'd with afterburner. i bumped it from 1000 mhz to 1025, then 1050. it ran furmark perfect on 1920x1080 burn-in test and the highest temp was 69c. then i bumped it straight to 1100, and it ran it fine, top temp at 69c. then when it closed out and was about to show me my pc specs, the window of the specs was kinda fuzzy. then it went black a few times. then came the blue screen. i had the fan speed of the gpu at 50% the whole time. i didnt touch anything other than core clock. any advice?
 

You do not buy a fan, it is pretty much pure luck. My 7770's were very different. One clocked to 1300/1444 and the other wouldn't budge past stock.

It might not have been stable. But furmark is also a very poor stress test, it burned out my GPU. I would run valley and haven. Make sure to slide power tune to +20%. ;)

Ok. I did run valey, and it wasn't the best fps lol. And wo
Nt turning up the power so much over volt the card and burn it out? And im thinking about hitting dat OC genie 2 buttion on my mobo. is it safe to OC my gpu with afterburner at the same time as OC genie is going? i have a MSI A85XA-G43 mobo.

 

Powertune increase the amount of power the card can draw, not it's voltage. I have no idea of OC genie and GPU OC play nice, but they should.

I downloaded valley, and is it ok for me to up the voltage on a 500w 80plus rated psu (its not bronze, its just 80plus)?

cool! thanks dude! and in haven i think i noticed screen tearing, but it might've just been lag. not really sure.
 


Screen tearing is not a GPU overclock problem, but an issue caused by the GPU not outputting frames in sync with the monitor. In games you can use vsync.
