Biso007 Posted December 4, 2013 Share Posted December 4, 2013 I have Mavericks 10.9 on HP Elitebook 8460 (Intel core i7 SB 2640M 2.8 GHz) and have the following: - Patched AICPUPM installed and loaded w/o KP - AppleLPC.kext is loaded - SSDT with 13 frequency multipliers (800 -> 2800) - DSDT patched for LPC and HPET and no errors Yet I can't get except only 2 frequencies (800 MHz and 2800 Mhz) Any advice whether this is normal for this laptop or am I missing something ?

Lordadmiral Drake Posted December 6, 2013 Share Posted December 6, 2013 I'm getting min and max frequency even with NullCPUPM installed, so no, its not normal Link to comment https://www.insanelymac.com/forum/topic/294369-pm-very-few-cpu-frequencies/#findComment-1973978 Share on other sites More sharing options...
styrian Posted December 6, 2013 Share Posted December 6, 2013 @Biso007 This issues seem to be related with the used SMBios. If you are using one of a MacPro, than the steps are looking normally. Using the SMBios of a MBP 8,2 or 8,3 could help to get more steps. You should also set DropSSDT=Yes in your bootloader and generate no P or C states with it. Have fun.

Biso007 Posted December 12, 2013 Author Share Posted December 12, 2013 Thx for the tips ... Im using these steps as well and I'm using MBP 8,3 SMBios file ... still with only 2 frequencies Link to comment https://www.insanelymac.com/forum/topic/294369-pm-very-few-cpu-frequencies/#findComment-1975407 Share on other sites More sharing options...
toleda Posted December 13, 2013 Share Posted December 13, 2013 - SSDT with 13 frequency multipliers (800 -> 2800) Sandy Bridge ssdt pm must have every freq specified, min to max turbo +1, no gaps, 0x0800, 0x0900, 0x0A00,.. 13 is not enough. Search PikeRAlpha's ssdtPRGen.sh for best ssdt solution. 1 Link to comment https://www.insanelymac.com/forum/topic/294369-pm-very-few-cpu-frequencies/#findComment-1975420 Share on other sites More sharing options...
styrian Posted December 13, 2013 Share Posted December 13, 2013 @Biso007 Is an allround hacking kext like MyHack.kext in S/L/E of your install trolling around? Have fun.

Biso007 Posted December 22, 2013 Author Share Posted December 22, 2013 @toleda @styrian .. thx for your reply ... sorry to tell you that it's been my mistake to think that my patched AICPM kext is working. In fact I discovered that NullAICPM was loaded from /Extra folder ... when it's removed I get KP panic while booting. Now I have no DSDT or SSDT and I get the same 2 frequency multipliers (x8 and x28). So, I 'm back to square zero as I can't find a way to load AICPM without KP. Any advice ? (HP Elitebook Core i7 2640M 2.8 GHz with BIOS F22).

styrian Posted December 22, 2013 Share Posted December 22, 2013 If you have other kexts in a folder Extra/Extensions/ install them, if you really need them, in S/L/E. With ML up there have to be no more kexts in Extra folder. You could try to install nullcpupowermanagement kext temporary in S/L/E of your partiton and also the original, unaltered AppleIntelCPUPowerManagement.kext from S/L/E of your USB installer with your preferred kext utility and run after a reboot with flags -f -v the from Downloads gotten ACPM patch script. Get the from Toleda suggested script to generate a SSDT.aml and place it in your extra folder. You should also set the before suggested keys in your org. chameleon.Boot.plist. After putting nullcpupowermanagement.kext to trash and rebooting with flags -f -v, your PM should work, if you have done a vanilla install. I am thinking, that a working PM to get correct C steps does not depend on having a correct DSDT.aml. Working sleep is perhaps an other story. Have fun.

Biso007 Posted December 23, 2013 Author Share Posted December 23, 2013 Now I have ... patched AICPM in /S/L/E generated SSDT in /Extra with 20 P-states (loaded under CPU0 in IOReg) boot.plist with P-state=No, C-state=No, Drop SSDT=Yes SMBios = MBP 8,1 I still get KP for AICPM .. I had to put NullCPUPM back in /E/E ...I guess this laptop BIOS doesn't fit with PM. thx for your support Link to comment https://www.insanelymac.com/forum/topic/294369-pm-very-few-cpu-frequencies/#findComment-1978238 Share on other sites More sharing options...
styrian Posted December 23, 2013 Share Posted December 23, 2013 Sound over VoodooHda? If you really need Nullcpupowermanagement.kext, install it in S/L/E not in E/E. Are you running a mkext file? Have fun. Link to comment https://www.insanelymac.com/forum/topic/294369-pm-very-few-cpu-frequencies/#findComment-1978307 Share on other sites More sharing options...
Biso007 Posted December 24, 2013 Author Share Posted December 24, 2013 Yes I use VoodooHDA for sound ... does it relate ? No I don't have any mkext file.

styrian Posted December 24, 2013 Share Posted December 24, 2013 Try to remove VoodooHDA. It often gives KP. Have fun. Link to comment https://www.insanelymac.com/forum/topic/294369-pm-very-few-cpu-frequencies/#findComment-1978488 Share on other sites More sharing options...
Biso007 Posted December 24, 2013 Author Share Posted December 24, 2013 It doesn't give KP now ... do you mean it gives KP with AICPM ? so to get it correct, you want me to install AICPM and remove NullCPM and VoodooHDA ?

styrian Posted December 24, 2013 Share Posted December 24, 2013 Yes, just a try. You could also try to rollback the ACPIplatform to the one of 10 8.5. Have fun.
