Damn. I've got 5x Gigabyte WF3 280x in a rig. TC 8192, -g 2, 1040/1500, getting 725KH/s. Best part? Undervolted to 1.019V and running off 2 Rosewill 750 Capstone Modular PSUs. Pulls 1250W at the wall (combined). Undervolt FTW!
5xGigabyte Windforce 3Gb??? how are you under-volting? Flashing the bios? To what?
Thanks!
