macyB Posted April 27, 2014 Share Posted April 27, 2014 Hey, I really need Expert's help regarding power management for ivy bridge i7 3537U. CStates,PStates stuck at x8 Currently i am using Mavericks OS X 10.9.2 (13C1021) without any DSDT. No NullCPUPowerManagement. patched AppleIntelPowerManagement. SMBios: - MacBookPro 10,1 (suggested by piker alpha) - Also tried MacBookAir5,2. - Boot fine with both until this step. This is how i am doing it: Downloaded script from here: https://github.com/Piker-Alpha/ssdtPRGen.sh/blob/master/ssdtPRGen.sh in terminal: sudo /Users/USERNAME/Desktop/ssdtPRGen.sh-master/ssdtPRGen.sh -w 3 Result: ssdtPRGen.sh v0.9 Copyright (c) 2011-2012 by † RevoGirl v6.6 Copyright (c) 2013 by † Jeroen v13.2 Copyright (c) 2013-2014 by Pike R.

SSDT.aml placed in /Extra CStates, PStates set to No DropSSDT=Yes after reboot i get Kernel Panic in normal mode but was able to boot in safe mode. i searched that panic, found SSDT need some tweaks and found below solution: From: Name (APLF, Zero) Name (APSN, 0x0C) Name (APSS, Package (0x19) { Package (0x06) { 0x0C1D, 0x4268, 0x0A, 0x0A, 0x2000, 0x2000 }, Package (0x06) { 0x0C1C, 0x4268, 0x0A, 0x0A, 0x1F00, 0x1F00 }, To: Name (APLF, Zero) Name (APSN, 11) Name (APSS, Package (0x18) { //Package (0x06) //{ // 0x0C1D, // 0x4268, // 0x0A, // 0x0A, // 0x2000, // 0x2000 //}, Package (0x06) { 0x0C1C, 0x4268, 0x0A, 0x0A, 0x1F00, 0x1F00 }, Kernel Panic gone, booting perfectly fine. Now P States in DPCIManageer (tried intel power gadget too): 4/27/14, 2:25:08 AM, Current State: 8 4/27/14, 2:25:08 AM, P States: 8 4/27/14, 2:25:03 AM, Current State: 8 4/27/14, 2:25:03 AM, P States: I/O error, throttling to 9Hz PStates stuck to 8 and never change. Without SSDT, CStates, PStates set to Yes DropSSDT=No then i get only two PStates 8, 19 Please let me know if you need further details to figure out the problem. I searched a lot and tried many methods but all in vain. Its my 6th Installation of OS X today Quote Link to comment Share on other sites More sharing options...
mnfesq Posted April 27, 2014 Share Posted April 27, 2014 This is what worked for me. http://www.insanelymac.com/forum/topic/290687-wip-hp-envy-17t-j000-quad-haswell-1085109/?p=2006590 Quote Link to comment Share on other sites More sharing options...
macyB Posted April 27, 2014 Author Share Posted April 27, 2014 This is what worked for me. http://www.insanelymac.com/forum/topic/290687-wip-hp-envy-17t-j000-quad-haswell-1085109/?p=2006590 Thanks for quick response. I already tried both ways but no luck. -TURBO 3100 and -w 3 Did you modify your SSDT?? As i mentioned if i don't apply that tweak to my SSDT i get kernel panic in normal mode.

mnfesq Posted April 27, 2014 Share Posted April 27, 2014 If it's not your SSDT, it may be your smbios. Which are you using and what type of motherboard do you have - sandy, ivy or haswell? Quote Link to comment Share on other sites More sharing options...
macyB Posted April 27, 2014 Author Share Posted April 27, 2014 If it's not your SSDT, it may be your smbios. Which are you using and what type of motherboard do you have - sandy, ivy or haswell? Please check my signatures for laptop specifications. MacBookPro 10,1 was stucked in x8 so i changed smbios and regenerated the ssdt using method mentioned above. (-w 3) - This time ssdt code is different than before, i did not tweaked it, also i did not get kernel panic. right now i am using MacBookAir5,2 HWMonitor showing c,pstates x8 x19, 792Mhz 1.88Ghz no more.

pokenguyen Posted April 27, 2014 Share Posted April 27, 2014 For IvyBridge U CPU, you can try using MacBook Air 5,2, patch your mach_kernel with this http://www.insanelymac.com/forum/topic/293503-haswell-early-reboot-mavericks-locked-msrs-and-hp-envy-15-j063cl-i7-4700mq/ (no need if you're using Clover), then boot with "-xcpm" bootflag. After restart, use ssdtprgen to regenerate ssdt (with/without -w 3) 2 Quote Link to comment Share on other sites More sharing options...

pokenguyen Posted April 27, 2014 Share Posted April 27, 2014 Add xcpm to your org.chameleon.boot.plist, set drop ssdt=yes, generate=no Quote Link to comment Share on other sites More sharing options...
macyB Posted April 27, 2014 Author Share Posted April 27, 2014 Add xcpm to your org.chameleon.boot.plist, set drop ssdt=yes, generate=no Great thanks! its working now. P States: 8, 14, 17, 20, 24, 25, 29 but still not showing Max Turbo Frequency 3100MHz any suggestions? Quote Link to comment Share on other sites More sharing options...
pokenguyen Posted April 27, 2014 Share Posted April 27, 2014 3100Mhz is 1-core Max Turboboost, and CPU rarely reaches that state. Quote Link to comment Share on other sites More sharing options...
mnfesq Posted April 27, 2014 Share Posted April 27, 2014 Put CPU Package in HWMonitor on your menu bar and run Geek Bench. That should help you see if your laptop ever reaches 3100 MHz. Quote Link to comment Share on other sites More sharing options...
macyB Posted April 28, 2014 Author Share Posted April 28, 2014 Put CPU Package in HWMonitor on your menu bar and run Geek Bench. That should help you see if your laptop ever reaches 3100 MHz. Cool its working P States: 8, 14, 17, 20, 22, 23, 24, 25, 28, 29 HWMonitor shows x30 x31 when it does then DPCIManager show this error P States: I/O error, throttling to xHz thanks guys for all your help!

I've searched all day long getting speedstep to work but still stuck at 0,8GHz. BTW I also noticed that I get KP with the mac mini 6,2 smbios so I decided to stick with imac 13,2 Grtz Metalcored00d EDIT OMG it worked!! Thank you so much!! =') Quote Link to comment Share on other sites More sharing options...
