Nah, 1000 mV is too low for 1120+ Mhz. Then I'm not sure the undervolt works. I suspect the bios says "yes" but gives you the finger when you're not looking...


you too have it at 1050mv?
Yes, that is what I set on my Gigabyte R9-270's with the VBE7 bios editor. However, this is not the value reported by Hwinfo software.

Currently to mine non-scrypt coins where heat, power and component stress aren't such a concern, I set them to 1.15V and overclock to 1.2 Ghz. They obviously respond to the higher voltage, but not so well to lower.

my r9 270 rigs are undervolted to 1050mv and are hashing at 480kh/s.. Anyone is able to get them steady at 1000mv or lower?
