No SpeedStep

[polemos]

I've installed with "Alternate Guide #1 – OS X Snow Leopard Install using Retail DVD" method.Updated to 10.6.4.
I'm checking with command : sysctl -a | grep freq

hw.busfrequency = 532000000
hw.cpufrequency = 2664000000
hw.tbfrequency = 1000000000
hw.busfrequency: 532000000
hw.busfrequency_min: 532000000
hw.busfrequency_max: 532000000
hw.cpufrequency: 2664000000
hw.cpufrequency_min: 2664000000
hw.cpufrequency_max: 2664000000
hw.tbfrequency: 1000000000

And machine dosen't go to sleep.Something halts but power led is on.And it can't come back.

Did you remove the NullCPU....kext?

 

[polemos]

Removed.Now sleep works.But i couldn't see any change about speedstep.

sysctl -a | grep freq
return same value in real MBP

it's not good system for viewing speedstep
i have bookmark this one
first off all

kextstat -l | grep LPC
should return com.apple.driver.AppleLPC

ioreg -lw0 | grep CSTInfo
should retrurn a value like (		"    | |     |   "CSTInfo" = 19136773")

ioreg -lw0 | grep PerformanceStateArray
should return (		"    | |     |   "PerformanceStateArray" = (<f00a0000281d01000a0000000a0000000015000000150000>,<6b0a0000e8fd00000a0000000a etc etc ")

after there is only latest fakesmc and K-stat or similar who can view real CPU freq or core Voltage

First two commands gave me nothing.Last one gave some numbers :

| | | "PerformanceStateArray" = (<650a0000187301000a0000000a0000000015000000150000>,<640a0000187301000a0000000a0000000014000000140000>,<df090000b03001000a0000000a0000000013000000130000>,<5a090000701101000a0000000a0000000012000000120000>,<d5080000a8de00000a0000000a0000000011000000110000>,<5008000038c700000a0000000a0000000010000000100000>,<cb07000028a000000a0000000a000000000f0000000f0000>,<46070000a08c00000a0000000a000000000e0000000e0000>,<c1060000606d00000a0000000a000000000d0000000d0000>,<3c060000a86100000a0000000a000000000c0000000c0000>,<b7050000384a00000a0000000a000000000b0000000b0000>,<32050000684200000a0000000a000000000a0000000a0000>,<ad040000c83200000a0000000a0000000009000000090000>)

I also have to add that i've used DSDT-GA-P55-US3L-2.0-FH.aml

my ref is compilation in french
Activer la gestion de l'énergie du processeur sous OSX (Màj) => darwinx86.net

at last page there is all international ref for speedstep installation and control. A must have isn't it ?

setting iMac11,1 in smbios should make Speedstep a lot easier, but I had to remove AppleIntelCPUPowerManagement.kext in S/L/E to make it work on my old board, dunno if for P55 it's still required..
