Overclockng a voltage locked HD7970

post #1 of 6
Thread Starter 
Hi,

I have a voltage locked Gigabyte HD7970 WindForce 3x... i assume it's voltage locked as I cannot change the voltage even after using unofficial overclocking in afterburner. I want to OC it as a recent upgrade from 1920x1080 to 2560x1440 hurt BF4 performance a lot!

I see there is an option "power limit%"... is this potentially dangerous to turn up? Does increasing it reap better clock or memory speeds? I planned just to up by 50MHz and test it in game per night. I'm also using catalyst 14.4 drivers.

Any advice for overclocking a voltage locked card? I don't want to flash BIOS etc...

Nope. it won't damage the card if you were to increase the power limit. Second, have you tried Sapphire Trixx to try and overclock the card, as there are quite a few brands that Trixx Allows user to control voltage

Ooh, no I didn't try that... I will give it a go.

Something specific about Trixx that unlocks voltage control where other cards cannot or?

Maybe you could find a different BIOS for the card? I'm sure there's a BIOS you can flash it with that will allow more voltage control

Not sure why, but i have a MSI and a Sapphire 7950's and i cannot adjust the voltage on MSI without the AB hack, but with Trixx, they give voltage control all the way to 1.3v.

Nah, not so interested in BIOS flashing. I don't really have the time nor patience if it goes wrong tongue.gif
