Hello,
I have a Sapphire 7970 OC w/boost (the blue PCB one), and I'm using MSI Afterburner to overclock it. I am using the second BIOS setting, where the core clock is 1000mhz and memory is 1425mhz.
My card's ASIC quality is 81.7%, so its stock voltage is 1050mV.
Initially, I was confused as to why I couldn't get to 1050mhz core without the display driver crashing and occasional artifacts in games. However, upon checking MSI Afterburner's hardware monitor and looking at the voltage, even though I have upped the voltage to 1113, and even 1163 at one point, the hardware monitor says that the card's current voltage is still 1050. I can change the slider fine, but it seems to have no effect on the card.
How can I change the voltage? I'm assuming this is the reason I can't OC the card very much right now. I have added the EULA into the .cfg file and enabled unofficial overclocking and such.
I remember when I tried the newest version of TriXX, I couldn't even find a gauge or slider that allowed me to change the voltage.
I'm pretty sure this card isn't voltage locked, how would I actually change the voltage?
Thanks
EDIT: Apparently ticking "force constant voltage" makes my voltage applied, and it seems to work in game, but I would like to avoid that if possible (although my card seems to always run at 1.050V anyways). Is there any other way to do this? I'm thinking of just using VBE7 and flashing my own custom BIOS onto the card.
