So I just flashed both cards with the latest Asus bios from TPU to even them out, but now I am getting weird behaviour with idle clocks and volts. Either I disable overdrive in CCC and get my low idle clocks of 157/300, but full VGPU in idle, OR I enable overdrive and get lower VGPU (1,06V, used to be 0,95V with the old bios) but very high idle clocks of 400/1200.
What's the deal with this? I don't wanna blow power out the door for two cards that are idle 90% of time.

Any other recent bios I should use instead? Or just go back to the original unlocked Asus bios back from September 09 and be done with it?

Thanks.

PS: I never had any issues with the low idle clocks (screen flicker or whatever people have been posting about). I only run 1 screen though.
That was the Ati bios to fix couple of Eyefinity problems. Thats also why the 2d clocks are higher as its for ultra high resolutions.
Just flash back. Those old roms are ok
