What works

  • Sleep
  • iServices
  • Everything seems to everything work to me

This configuration is a bit old, but very cheap, stable to build, and stable. EFI works with almost no modification by building for Ivy Bridge using OC-Gen-X. All you need to do is add radpg = 15 to get the HD7870 working and VoodooTSCSync.kext needed to fix the TSC.
