Yep, we got a bunch of Gigabyte 280x. A little VBE7 to undervolt the BIOS, and they're hashing in Linux and Windows just fine @ 725Kh/s. Very quiet, and cool.
What voltage do you use?
725Kh/s @ 1025/1500 @ 1.019V
What's the advantage of using VBE7 instead of Trixx or Afterburner?
1.019V is really low. I can't go lower than 1.100V using Trixx.
Are the voltages that are displayed in Trixx or Afterburner different form the "real" voltages?
