iapple0520 Posted September 17, 2017 Share Posted September 17, 2017 My CPU is Intel i7-3770 (3.4 ghz) and it can turbo to 3.9 ghz. And my OS version is Sierra 10.12.6 install by clover and #####. At first, my CPU block at 3.4 ghz due to XCPM of ivy bridge is disable in Sierra. Then I open XCPM in Clover Configurator - Kernal and Kext Patches - KernelIvyXCPM I use the and boot clover with argument -xcpm and i7 3770 can turbo to 3.9 ghz successfully. However, there are only 6 channel at all, 1.6, 3.4, 3.6,3.7,3.8,3.9. I'm wondering is this correct or there should be any method open the channel between 1.6 and 3.4 Thanks!
