Power Mangement Speed Step i7 3770k

crusher · May 8, 2014

Hello!!!I have a problem via my CPU Power Management P-State i7 3770k.

Which Mac definition for my CPU Mac board id.

I have a MacPro6,1 but don't work I have a one P-state 8.....

I create my SSDT via this link.

Thanks in advance!!!!

hello

u set ivy workaround ?

-workarounds for Ivy Bridge [0/1/2/3]
0 = no workarounds
1 = inject extra (turbo) P-State at the top with maximum (turbo) frequency + 1 MHz
2 = inject extra P-States at the bottom
3 = both

see the read help

good hack

Look what I use!!!And my SSDT and ssdtPRGen.sh

Link.

workaround I use a -w 1!!!!

Ok I know,but I have a this error on boot.What is this?

PM kernel[0]: IOPPF: XCPM mode
PM kernel[0]: XCPM: P-state table mismatch (error:0x11)
PM kernel[0]: X86PlatformShim::sendPStates - pmCPUControl (XCPMIO_SETPSTATETABLE) returned 0x11
PM kernel[0]: X86PlatformShim::start - Failed to send PStates
PM kernel[0]: X86PlatformShim::start - Failed to send stepper

I have a P-State on MSRDumper 16,25,30,35,37,38,39.

Hi All,

I am running my i7 3770K system without an SSDT and I have all P-States working. I have patched the kernel and I am using the -xcpm argument in Clover.

The point is, I am using the auto generated SSDT and the the system is very stable with speedstep working well. You also have to disable C3/C6/C7 Reports (Support) in the BIOS so as to let the XNU Kernel to do all the power management.

My system is in my signature below.

Sorry how to patch your kernel?

Thanks.

Hi All,

I am running my i7 3770K system without an SSDT and I have all P-States working. I have patched the kernel and I am using the -xcpm argument in Clover.

The point is, I am using the auto generated SSDT and the the system is very stable with speedstep working well. You also have to disable C3/C6/C7 Reports (Support) in the BIOS so as to let the XNU Kernel to do all the power management.

My system is in my signature below.

Was patching the kernel necessary?

Also are those the only settings you have enabled for Clover?

Also either way I try it I get errors like this

6/4/14 7:51:49.000 PM kernel[0]: XCPM: registered
6/4/14 7:51:49.000 PM kernel[0]: IOPPF: XCPM mode
6/4/14 7:51:49.000 PM kernel[0]: XCPM: P-state table mismatch (error:0x12)
6/4/14 7:51:49.000 PM kernel[0]: X86PlatformShim::sendPStates - pmCPUControl (XCPMIO_SETPSTATETABLE) returned 0x12
