howoarang Posted October 27, 2014 Share Posted October 27, 2014 Hi, in my laptop Dell Latitude e6500 I have CPU C2D T9600 @ 2,8GHz. My Temperature in IDLE mode is about 60-62 C per Core. I have latest FakeSMC.kext installed with CPU, GPU, LPC and ACPI sensor.kexts included. Under Windows on same laptop I have temperatures in IDLE mode about 40-42 C. Why? TJmax of this CPU is 105 C. Can somebody help with its? How to configure DSDT.aml, or config.plist or some kexts to show correct temperature? Mac OSX Yosemite, Clover bootloader.

jl4c Posted October 27, 2014 Share Posted October 27, 2014 What about your PM? is AppleLPC loaded? Anyway, attach dsdt and IOReg. Link to comment Share on other sites More sharing options...
Allan Posted October 27, 2014 Share Posted October 27, 2014 Put C and P states in ACPI section. Link to comment Share on other sites More sharing options...
fusion71au Posted October 27, 2014 Share Posted October 27, 2014 Those temps do seem a little high (but not critically high).... My XPS M1530 with C2D T9300 averages about 48-60 deg C. P & C states generation is set in my config.plist - see my configuration here. Temps running in OSX are typically about 10 deg C higher than in Windows 7 X64 due to non functioning C states on Dell C2D Laptops (even though AppleLPC.kext loads with DSDT edits, it remains non functional, hence the warning "WARNING - LPC device initialization failed: C-state power management not initialized" in the boot messages. @Slice mentions that "I think with Dell notebooks it is impossible because of LPC device is differ from Apple's".

howoarang Posted October 28, 2014 Author Share Posted October 28, 2014 Hi, here are my DSDT.aml, config.plist and IOreg. C,P states are enabled in config.plist of Clover AppleLPC is NOT loaded, see screen. It is needed to have AppleLPC loaded, if yes, how? And I have 2nd question about voltage of CPU: In Windows, my CPU has in IDLE mode voltage 0.9 V In OS X is this voltage 1,01 V CPU frequency + clock multiplier are the same in booth systems. In IDLE mode is frequency 798 MHz (800 Mhz in original) and multiplier 6x. (6 x 133MHz FSB = 798MHz) In STRESS mode are 2,79 GHz (2,8GHz in original) and multiplier 10,5x (10,5 x 266MHz FSB). I think, these values are correct. config.plist.zip DSDT.aml.zip e6500.ioreg.zip Link to comment Share on other sites More sharing options...
howoarang Posted October 28, 2014 Author Share Posted October 28, 2014 yes, in Clover config.plist -> CPU tab I have 266 666 kHz as Bus Speed, it is ok. AppleLPC.... which pc id from the kext I must inject to DSDT.aml? There are many of PCI IDs... Link to comment Share on other sites More sharing options...
jl4c Posted October 28, 2014 Share Posted October 28, 2014 Patched dsdt. BTW, your IOReg is corrupt, after reboot attach it again. dsdt.aml.zip 1 Link to comment Share on other sites More sharing options...
howoarang Posted October 28, 2014 Author Share Posted October 28, 2014 Thanks @ jl4c AppleLPC is now loaded. And this is IOREG again (I use IORegistryExplorer.app) e6500.ioreg.zip Link to comment Share on other sites More sharing options...
jl4c Posted October 28, 2014 Share Posted October 28, 2014 Still corrupted, use "Save a Copy As..." IORegistryExplorer-SLRID_v10.6.3.zip Link to comment Share on other sites More sharing options...
howoarang Posted October 28, 2014 Author Share Posted October 28, 2014 I have used "Save a Copy As", really. I don't know, why is it still corrupted. And this is with your registry.app v2.1. I have v 3.0.2 e6500.ioreg.zip Link to comment Share on other sites More sharing options...
jl4c Posted October 28, 2014 Share Posted October 28, 2014 Good, now boot with "Drop OEM". Attach IOReg again. Link to comment Share on other sites More sharing options...
howoarang Posted October 28, 2014 Author Share Posted October 28, 2014 @ jl4c - What you mean to boot with "Drop OEM" ? Sorry for my weak acknowledges. It is command to add in boot flags? @ Hervé - T° are the same . Now, when the laptop was OFF about 2 hours, Temps are about 50 - 53°C. I think, it is good.

howoarang Posted October 29, 2014 Author Share Posted October 29, 2014 Oh yes, I found it this is IOREG again with "Drop OEM" And I have one question: Can the CPU has effect to correctly run of system time and playing videos in Safari? I take note that with system time is something wrong, as if it will be stopped or paused for a while and later goes well. 2nd problem is playing videos or movies via Safari. Almost in every playing videos is sound ahead about 2-3 sec. I don't know if it is bug in Yosemite. But in previous versions of OS X I used Chameleon bootloader and have no problems. And now, I am using Clover and have many problems like CPU temperature, paused system time, delay videos playing, slower, lagging and freezing system animation... e6500.ioreg.zip Link to comment Share on other sites More sharing options...
