Getting speedstep with P8P67 pro -2103 bios with 2500K to work!

[j2quinn]

this is a 10.7.4 related question.

I have a p8p67 pro modified bios 2103. now i have tried several routes to get speed stepping to fully work with several p states however none have worked so far. i only get 16 and 33/34

first, i used the DSDT for 2103 p8p67 pro from DSDT database and the stock i5 SSDT from multibeast 4.6.1. including patched applepowermanagement. didnt work. 16 and 33 states only.

second, i used the DSDT for 2103 p8p67 pro from DSDT database and the stock i5 SSDT from multibeast 4.6.1. including patched applepowermanagement. this time i included the p states from the SSDT and overwrote the ones in the DSDT. didnt work. 16 and 33 states only.

third, i used the same technique above but used Revogirl's script to produce (TDP=95 MaxTurbo=3700) a SSDT and copied that ssdt pstates to the dsdt. didn't work. 16 and 33 only.

so i am kind of lost on how to get multiple pstates going other than 2!

any idea?

is this BIOS related? i have AUTO for most things or enabled. it says in bios menu that the turbo freq is 3700.

Did you delete NULCpuPowerManagement?

Did you delete NULCpuPowerManagement?

i renamed it. in theory that should be the same.

the other thing. if i add DropSSDT=yes to the kernal flag in my plist. it doesn't boot. just stalls. no KP.

im lost. i used a ubuntu live cd to pull off DSDT.aml and SSDT.aml.

my SSDT has no CPU references. they are only located in the DSDT.aml

SSDT.aml

All I needed to do was install the overclocked SSDT and delete NullCPU

 

[j2quinn]

do you have a DSDT? what pstates do you have and from where? i only get more pstates if i go to sleep and wake up.

 

[Koalaman]

No I do not have a DSDT. Wait a bit..

 

[j2quinn]

was able to get

16 34 35 36 37 by deleting the DSDT and keeping just the stock i5 multi beast 4.6.1 SSDT.aml. removed GenerateC/PStates and DropSSDT yes statements.

going to try different SSDTs..

Revogirl's vs Multibeast Vs Etc...

and also try different SMBIOS'

In ML I've read that an SSDT is not needed for 2500k speedstep.

Im using P8P67 Pro + 2600K no DSDT just SSDT.aml from multibeast.

Lets just say it doesnt work, Ive already got a patched BIOS which enables speedstep and this used to work fine in LION.

Here I am using mountain lion and getting less than half the scores in cinebench and geekbench.

Not sure what the problem is??? can someone here with the same or similiar motherboard post there chameleon boot.plist please?
