I can currently volt up to 1.2125 which puts me stable at about 940 core clock. I'd really like to be able to overvolt to 1.35v like I can in windows using MSI Afterburner or Asus SmartDoctor.http://www.newegg.com/Product/Product.aspx?Item=N82E16814121374
is my card for reference. I can definitely reach 1000 core clock easily by upping the voltage in windows, but I can't get past what seems to be a hardcoded bios limit of 1.2125 in linux.
I've tried using the Radeon Bios Editor, but when I get to the clocks page I get the following:http://img402.imageshack.us/img402/8150/screenshotuhq.png
the gpu / voltage registers are grayed out and when I try to manually set my voltage to 1.35v for Clock Info 03, aticonfig won't recognize the card in linux anymore even when I reinstall the drivers. RBE forums say this is because you have to change the voltage in the registers, but they are blanked out for me.
Does anyone have a working bios for my card that allows the voltage up to 1.35v OR a tool in linux that will let me volt as high as Asus Smartdoctor? Thank you.
