Powercolor 7870xt

post #1 of 11
Thread Starter 
Hello OCN,

I currently have a 7870xt, and for some reason the voltage wont stay locked. It always boosts to 1.25 volts on load. I tried updating the BIOS to the latest one from the 7870xt club. I believe it is the 31 bios. I have tried using Trixx and MSI afterburner. I manually set the voltage to 1.0v and the program takes it but it doesnt seem to work at all. I unlocked voltages, set constant voltages, allow overclocking, and disabling ULPS with no luck. Drivers are 15.7.

Is there a modded BIOS out there to allow to change the voltage with no issues?

Thanks

Your card may be voltage locked. However you can still mod its BIOS and set it to your desired voltage.

You can use powercolors official overclocking tool to change voltage. Not a very good program though...
