ML Overclock 2500k help

[Thade]

Hi all, I have a Gigabyte GA-Z68AP-D3 v1 and i2500k. It is a decent overclocker & I know what I can hit in Windows, Lion, SL

I'm using the OC SSDT.aml from MB but 1 MHZ over 33 multiplier results in "still waiting for root device" usually just after "appleintelcpupowermanagementclient" ready

I have found a couple of post suggesting setting individual multipliers with the last multiplier 1 MHZ less:

42
42
42
41

... but it doesn't seem to help. I may be missing something simple here? The same bios settings work fine in Lion & SL

any ideas?

TIA

Using NullCPUPowerManagement?

 

[Thade]

yeah, I realized I was in the wrong forum after I posted

I am not using NullCPUPowerManagement, still confused whether or not I should...

No you shouldn't be... I had the same issue months ago and don't remember how I resolved it. Are you using a newest UEFI bios?

No PM Kext should be needed. What Bios version are you using?

Thanks guys. I have not made the jump to UEFI and I'm on the latest version for my MB F8
