Hi Carmico,
Originally, I installed Lion and checked the CPU status with HW Monitor. I found that CPU ran
at x16 only and I supposed that speedstep did not work. So, I replaced the bios with Samisnake's
one and tried again. But I still got the same result. Finally, I installed Mountain Lion right away.
It was still the same. So, I read many posts from this forum and I understand finally that CPU
will stay at x16 when it is in idle. I open Terminal and typed "YES" to test. Then I got CPU running
at x31 and found that speedstep works. Basically, I don't know if Samisnake's bios makes it work
or not.
Cheers!
Looking to the Samisnake's bios thread seems that bios has to beed modified to get SpeedStep working.
btw, Cborg uses Samisnake bios, (v1.10 modified)
