ergot Posted October 22, 2014 Share Posted October 22, 2014 I am installing a new machine with the following HW: MB - Asus P6T WS PRO CPU - i7-920 RAM - 8GB DDR3 GPU - GT840 installation went OK, I have network, sound, GPU, sleep, restart,shutdown etc. however i can see that my CPU is not using all threads when running bench mark and the results are accordantly. the socket is LGA 1366, do i need to install VoodooTSCSync kext? If yes where I can find this kext for LGA1366 and Core i7? or it needed only for LGA2011...?

jl4c Posted October 24, 2014 Share Posted October 24, 2014 Sure. First, your system is not loading AppleLPC, then you don't have PM. What boot loader? What settings? Are you using SSDT?

jl4c Posted October 24, 2014 Share Posted October 24, 2014 OK. you have first generation CPU. Boot options: Generate P/C States. And make sure the AppleLPC is loaded. BTW i recommend to work with your own dsdt. Extract from linux and attach it here.
