Unfortunately it doesn't safe power for me, at least on my E8400 the power consumption raises about a hardly measureable bit. If I'm right the C7 (Eden V4, Esther in my case) supports enhanced speed stepping. I can enable it in my BIOS (along with SpeedStep1) which should enable the cpu to operate with 0.884 Volt. This would safe enourmous power. Unfortunately I can't hack the est driver to attach to C7. Any volunteers? :) Best regards, -Harry P.S.: I'll do some measurings regarding the throttling on the C7 to verify disabling throttling is the right thing ;)
