Thread Starter 
Hello i am havng a problem finding a way to unlock voltage i have the latest 12.4 drivers ive tried every program possible the only one that can read the voltage is asus gpu tweak but i cant unlock it passed stock even with the unnoficial overclock i have the card stable at 1175 core clock and 1600 memory clock with stock voltage i stressed tested it while i was at work came back home 0 errors and ive been playing at those clocks for over a week now so i feel like it has much more potential but i cant seem to unlock the damn voltage =( i also have it watercooled and the card never goes over 43 celcius with an ambient temp of 23 celcius can anyone help will be greatly appreciated im kinda very annoyed already.

Also tried with no success on Afterburner, ASUS GPU Tweak and Trixx with no success. Have used the "-tcl" switch on Afterburner to no effect. I think that only the DCII TOP has easily accessible voltage control, possibly the TOP model has a different VRM as when I put a TOP BIOS on my card it still refused to change VDDC :/ Two things tho:

- I can hit about 1.15 / 6.4 GH on stock volts - from what I've heard from TOP owners, they, like normal 7970s tend to max out around 1.2GHz if you limit yourself to acceptable voltages. Given you can get to 1.175 GHz enjoy the fact that you're only losing ~3% performance and don't have to touch voltage.

- I *think* you may be able to short two connectors on an exposed part of the PCB to get voltage control. However that may be designed exclusively to hook up to ASUS RoG boards - haven't looked much into this; its is posisble you can connect them to allow you to control VDDC via software.
