Title: R9 270 POST YOUR UNDERVOLTS WITH HASHRATES Post by: MinerP on March 18, 2014, 07:37:41 AM 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?

Then I'm not sure the undervolt works. I suspect the bios says "yes" but gives you the finger when you're not looking...

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. |
