dunghv Posted June 4, 2014 Share Posted June 4, 2014 I successfully installed Mavericks 10.9.2 on my Dell Latitude E6430 (detail specifications are listed in my signature). With guides from Pokenguyen, I also activated SpeedStep for Core i7 Ivy Bridge. I use AppleIntelCPUPowerManagementInfo.KEXT to check whether SpeedStep is activated or not. The result is YES. I got 5 step ! Good news. Recently, I checked on HWMonitor and found out that my CPU always runs at maximum speed (3.37GHz). Only when the laptop is awaken from sleep, the CPU runs at minimum speed. Even there is no application running but CPU is at maximum speed. Please be advised that I use FORCE QUIT to end all application except FINDER. Can someone help me identify the problem? May laptop consumes battery so fast and battery idicator does not update automatically. Thank you so much. Link to comment Share on other sites More sharing options...
Administrators Bronxteck Posted June 4, 2014 Administrators Share Posted June 4, 2014 try booting with the flag -xpcm at the chameleon prompt. if it reboots immediately after that then to test the -xcpm flag you will have to patch your mach_kernel. backup your original one first before patching.

pokenguyen Posted June 5, 2014 Share Posted June 5, 2014 I appreciated a lot your information. And, by the way, Is there any guide on how to patch match_kernel? Are you using Clover or Chameleon? Link to comment Share on other sites More sharing options...
dunghv Posted June 5, 2014 Author Share Posted June 5, 2014 Chameleon, pokenguyen. And, I did patch AICPUPM as your guide successfully. Therefore, I got 5 steps when checking by using AppleIntelCPUPowerManagementInfo.KEXT. Link to comment Share on other sites More sharing options...
pokenguyen Posted June 5, 2014 Share Posted June 5, 2014 If you want to patch kernel as Bronxteck said, run HVT and select Kexts > CPU Power Management > patch mach_kernel Or Run the following command in terminal: perl -pi -e 's|\x74\x6c(\x48\x83\xc7\x28\x90\x8b\x05..\x5e\x00\x85\x47\xdc)\x74\x54(\x8b\x4f\xd8\x45\x85\xc0\x74\x08\x44\x39\xc1\x44\x89\xc1)\x75\x44(\x0f\x32\x89\xc0\x48\xc1\xe2\x20\x48\x09\xc2\x48\x89\x57\xf8\x48\x8b\x47\xe8\x48\x85\xc0\x74\x06\x48\xf7\xd0\x48\x21\xc2\x48\x0b\x57\xf0\x49\x89\xd1\x49\xc1\xe9\x20\x89\xd0\x8b\x4f\xd8\x4c\x89\xca)(\x0f\x30\x8b\x4f\xd8\x0f\x32\x89\xc0\x48\xc1\xe2\x20\x48\x09\xc2\x48\x89\x17\x48\x83\xc7\x30\xff\xce)\x75\x99(\x5d\xc3)\x90{7}|\x74\x73${1}\x74\x5b${2}\x75\x4b${3}\x66\x81\xf9\xe2\x00\x74\x02${4}\x75\x92${5}|g' "/mach_kernel" then rebuild cache. 1 Link to comment Share on other sites More sharing options...

dunghv Posted June 6, 2014 Author Share Posted June 6, 2014 Bronxtech and pokenguyen ! Thanks so much for your guides. I did patch match_kernel and the problem was solved. By the way, do you have any recommendation for SMBios.plist for my laptop when updating to 10.9.3. I used SMBios enclosed in the EDP and got error when updating to 10.9.3 (system uptime in nanosecond ....) Thanks. Link to comment Share on other sites More sharing options...
