Using different cpu multis without AOD
If you want to change your cpu multis individual and don't want to use AOD you can use this method.
- Set "Cool'n'Quiet" to Auto (bad sideffect you can not use a
nb multi beside stock (9x or 10x) with newer bios versions. - Boot into windows make sure you have the phenom drivers from amd installed on winxp
- Under windows open the Energy Options Dialog and switch to the mode for lowest battery usage.
- Start AMD Power Monitor and CrystalCPU's MSR Editor.
This is how it looks here with an 9600BE

- Select a core In CrystalCPU's main window and read register 0xc0010064 in the MSR Editor. This is the register for the normal power state (p-state-0) at 0xc0010065 is the register for the energy saving power state (p-state-1). If you select "lowest battery usage" in the energy options dialog your cpu will run in p-state-1 in "Desktop" mode it's p-state-0.
- The last digit is responsible for the cpu-multi.
The frequency is 1600MHz+digi*100MHz, so in my case 1600MHz+700MHz=2300MHz.
Change it to your desired value and hit WRMSR. In my screenshots I choose core0 and 8 as the last digit means 2400MHz for core0. - In the Energy Options Dialog switch into "Desktop" mode. The cpu
will now use the new settings you defined in the p-state-0 register.

Beside the cpu multi you can also define CPU-VID,NB-VID, CPU-DID and NB-DID here. Look at page #24 of the "Official" DFI thread for further information.
