[Important] MSI Afterburner 3.0.0 Beta 7 features 7870 XT Voltage Control - Page 3

by increasing your voltage, you can maximise your overclock.

ie to achieve an overclock of 1200/1500 you may have to raise the cards voltage to 1.25

I can already achieve 1200/1600 but with some artifacts in Heaven DX11. Will increasing the voltage get rid of the artifacts?

yes, and I'd recommend keeping the memory clock at its default clock (1500). Negligible difference in performance and it could be causing your card to artifact.

I have the same problem @ 1200mhz using heaven. I had no luck with adding more voltage.

I have currently installed MSI Afterburner version 3.0.0 beta 9.
As of this version, i can modify voltage of my Powercolor 7870 Mysta Card, but only for the main Card. For the second card, one cannot modify the voltage, the bar appears inactive.

The question on my mind is, if i modify the voltage for the first card, with synchronizing on, will it automatically modify voltage for the second card also, or not ?
Because although the bar appears inactive, the slider is set higher, after i modify the voltage of the first with synchronizing on.

I think i should wait for another version of the program to be able to proper modify voltage.

What do you guys think ?

I get 1200/1500 on my joker with power limit +20%. Does this mean when it needs it it will up the voltage dynamically? If so, is there a way to have this on the OSD? I can't see any options for it in AB.

Is there anyway to do this with a 7950, i've been searching for around 2 months on how to unlock it! Flashing the bios does not work, unfortunately. My card model is 1002 - 679A, has a 8+6 pin, it's a Gibabyte 7950 WF3, with bios .FU0. My card is locked and i seem to be able to change the voltage in Trixx and Asus GPU tweak, GPU-Z also reads it when i change the voltage so im guessing it's not hardware locked. Im just stuck on the VDDC part what does C8 88 mean, I think this is the voltage? Could you say what number it is for 1169 voltage as stock voltage? Thanks!! biggrin.gif
