Asus Sabertooth Z77 doesn't overclock (i7 3770K)

[dmitriizosimov]

After clean install of Yosemite on a fresh drive (UB+MB, no BIOS resetting) tried Geekbench and scored 13000 as if the rig was on a default clock. HWMonitor revealed that Speedstep doesn't work: the freq is always the same 3,5Ghz. Back on Mavericks the clock would top 4,6Ghz and give me GK score of 17000 which I would love to see on Yosemite.

Any thoughts?

FWIW, I'm having the same issue with the same mobo/processor combo, although I seemed to have it in Mavericks as well.

Have you tried installing custom SSDT for your 3770k?
Also a patched AICPUPM is worth trying.

As far as I know, this mobo should work fine without DSDT.

Thanks in advance!
