I own a Sapphire 7870 XT Dual-X (Tahiti LE), 975 Mhz boost, at 1.25 V bios.
I have tried to lower the Vcore using trixx 4.8.2 (which works fine on 7870 Ghz, 7950, 7970, 280 and 280x, or MSI AB (which works fine on 290).
I also flashed a bios with lower voltage settings but the card will get stuck at 500 Mhz 0.95 V.
Is there a work around to lower its voltage to make it cooler (new thermal paste on) and consume less power?
Any help is appreciated
I found it
In MSI AB, if you flag the "Force constant voltage" option, it works !
Great !!!Edited by bolc - 7/4/16 at 2:21pm
