Long Idle is only when the card is doing nothing. Long Idle has no affect on mining.
Are you saying your system pull was 107W idle, or while mining? My computer's idle can vary anywhere from 86 to 96 (idle meaning not mining), so a 10W difference is hard to be tracked down or attributed to the GPU.
Also, I thought those 7xxx cards couldn't go to 300MHz mem? I thought they had to be within a certain range of the Core speed? Can you verify with GPU-Z that you are actually mining at 1100,300?
Thats what I thought. However, I don't get it. I verified that the HD was still spinning but indeed the watts used was down to 96 from 106. This is total system wattage. The system is just an intel g630 / 8GB / 2TB HD. Without the video card in the system and using the IGP it only uses 25W total. So this 7770 uses somewhere between 71 and 81W while hashing 205MH/sec @ 1100 / 300. Unfortunately games cannot be played @ 1100 but hashing seems ok.
Yes I can verify its @ 1100 / 300. I had to drop back to 12.3 drivers with the 2.7 sdk. I'm not sure if 2.6sdk is faster, haven't tested it. 12.6 drivers did NOT allow me to downclock vid memory below 925. 12.3 does. Hope this helps someone.
