Hey everyone,
I'm having some trouble installing OSX 10.5.5 on a separate HDD. My specs -

Gigabyte P55-USB3
Intel i7 950 @ 4ghz
2x GTX 460
G-Skill 16gb 1600

I used both speedstep and sleep kernals and got the same error, com.apple.driver.AppleIntelCPUPowerManagement kernel panic. I set my HDD to AHCI, tried disabling HT. Can anyone help me with this?
