marco.pisellonio80 Posted August 6, 2014 Share Posted August 6, 2014 Hello. I thought it was normal to have CPU cores on the 70°, but then I knew there is HWMonitor for windows and I wanted to try it. I've been several hours using Windows and I have rarely exceeded 50°, so maybe there was something to tweak that I miss in my hack! In fact building my hackintosh I never thought so much to power energy management, I was so worried to solve other problems of an installation by newbie. I remember that in Mavericks installation I did not selected anything about power management and I just enabled C and P states in ocbp. But I think that higher temperature reduces the potential life of my PC. Any suggestions? What are the kext interested in? What can I do decrase the temperature?

jamiethemorris Posted August 12, 2014 Share Posted August 12, 2014 Make sure you're not using nullcpupowermanagement. Make Sure that appleLPC is loaded: kextstat | grep LPCWhat CPU and mobo? Link to comment Share on other sites More sharing options...
marco.pisellonio80 Posted August 12, 2014 Author Share Posted August 12, 2014 This is the result: kextstat | grep LPC 32 0 0xffffff7f819d0000 0x16000 0x16000 org.hwsensors.driver.LPCSensors (280) <20 11 7 5 4 3> 89 0 0xffffff7f81ec7000 0x3000 0x3000 com.apple.driver.AppleLPC (1.7.0) <72 11 5 4 3> Cpu and mobo are in signature (MOBO: GIGABYTE GA-P55-USB3 - CPU: INTEL I5-760 2.80GHZ ). Unfortunately I discovered that my cpu is not Sandy bridge (as I thought) but clarkdale, so the SSDT script is useless. I don't have nullcpupowermanagement (you mean the kext in SLE, I suppose).

fusion71au Posted August 17, 2014 Share Posted August 17, 2014 @marco.pisellonio80, Those CPU temps do seem high. What SMBIOS do you use? I have very similar specs to you and my temps are much lower: GA-P55aUD3/Intel i5-750/XFX Radeon 5770 SMBIOS iMac 11.3, Clover Generated P & C States Temps from Kozlek's HWMonitor and iStat Menus range between 30-40 deg C. Get only 2 p states with iMac SMBIOS according to DPCI Manager ACPI section from Clover Configurator Maybe check your case ventilation and fans for dust as well... Good Luck Link to comment Share on other sites More sharing options...
vusun123 Posted August 18, 2014 Share Posted August 18, 2014 It seems that all hacks I have encountered, which use iMac as their SMBios only get 2 states, but using Mac Pro SMBios could help achieving more states Link to comment Share on other sites More sharing options...
marco.pisellonio80 Posted August 18, 2014 Author Share Posted August 18, 2014 Hmmm, thank you all. vusun123, I don't have AppleintelCPUMP and NullCPUMP in SLE, never had. I had smbios iMac 11.3, but Apple store didn't works, so I changed in Mac pro 4.1, and now it works. This could be the reason... I will try with HPET patch, and I will install next 10.9.5 version with smbios iMac 11.3. Link to comment Share on other sites More sharing options...
vusun123 Posted August 18, 2014 Share Posted August 18, 2014 iMac smbios won't give you more power states as it is now, Mac Pro is your friend here. Maybe try VoodooTSCSync kext, it syncs all cores in your CPU Link to comment Share on other sites More sharing options...
joe75 Posted August 18, 2014 Share Posted August 18, 2014 instead of the tscsync kext you could try VoodooPState.kext and the PStateChanger app http://www.mediafire.com/download/qg4eqqiaksdyt74/PStateChanger.zip http://www.mediafire.com/download/a53g313t3ldp0pw/VoodooPState.kext.zip Link to comment Share on other sites More sharing options...
marco.pisellonio80 Posted August 18, 2014 Author Share Posted August 18, 2014 Thank you. I'll try all them. I have to remove HWmonitor before? Link to comment Share on other sites More sharing options...
joe75 Posted August 18, 2014 Share Posted August 18, 2014 no, just install 1 Link to comment Share on other sites More sharing options...
marco.pisellonio80 Posted August 18, 2014 Author Share Posted August 18, 2014 I don't have time to test now, but It seems go better . CPU multiplier is x9 (before it was x22), and for now the degrees are 55°, all cores, and not increasing, but now I have to shutdown. I'll give you my news soon. But, wich is the function of PStateChanger app? I was not able to change anything... I suppose that the voodoo kext made the difference? Or not?
