1 Hi,
3 I googled this and found some other people asking the same question...
4 But I didn't find the answer.
6 I am using linux kernel vanilla to run on a AMD Phenom X6
7 1090T/ASUS Crosshair IV Formula system.
9 I enabled "ondemand" CPU frequency scaling givernor in the kernel and
10 "Cool'n' Quiet" in the bios of the board. I also enabled "Turbo Core"
11 in the bios (which says the 3200MHz is max and 3600 MHz in case of
12 Turbo Core being used.. I disabled C1E.
14 After Linux is booted (AMD64!) and idled, the CPU is running at 800Mhz (nice!)
15 and at 3200 MHz when system is under load.
17 But:
18 With prime I put exactly two cores under load, so normally Turbo Core
19 would kick in...but the clock of those both cores show 3200MHz instead
20 of 3600MHz....
22 How can I make use of the Turbo-Core feature unde Linux?
24 Thank you very much in advance for any help!
25 Have a nice weekend!
26 Best regards,
27 mcc
