One full day for me, I'm quite pleased. Unplugged at about 2am till 9pm. I have -150mv across the board but the overclock freqs reboot during benchmarks, but I don't use those enough to tweak them. My everyday clock speeds are 96 MHz to 1512 MHz. Screen off max is 486 MHz. Using cfq with smartass v2. A few versions ago I could get down to the low 700's in the bottom five freqs but hey, this is respectable.
Maybe I should mention I'm on latest task aokp and this is day after a full wipe install. May vet better after a couple cycles but its great even it it doesn't.
