This question is targeted to those with bios modded 690's. I recently modded mine 2 690's to introduce 150% power and 1.175 volts. I'm completely on water and neither card peaks above 45 degrees ever. My question however is, with the new bios, is anyone finding a hard time clocking them? i used to be able to run 1.15 volts, 130% power target and be able to sync all cards to +150 core and +200 memory on precision. Now with extra voltage and 150% PT I can barely finish valley with a clock at all. What is everyone else experiencing. Also is it in my interest to clock each core separately? I started and have gotten some really weird results such as:
GPU1: +153mhZ core/+200 memory
GPU2: +145mHz core/+500 memory... is this normal?!
Have yet to do GPUs 3 and 4.
Not sure if my PSU is limiting me as I also have a 3930K running at 5.0Ghz. My AX1200 is coming Wednesday.
Love to hear what others have experienced. Rocking the following:
EDIT**: my 1000W power supply just isn't enough at the clocks/speeds pumps, etc that I'm pushing this thing at.
