10.7.4 Sandy Bridge CPU Power Management Fix

[ovb1]

I followed OP, added three more P-States to the SSDT.aml from the Customization > Boot Options > SSDT >Core i5/i7 Overclocked selection in MultiBeast 4.5.1 and everything is OK! I'm OC at 4.5Mhz running 10.7.4.

This is awesome. Thank you.

Hey would you mind sharing your SSDT ? Then I can revert back to my original OC. Thanks

Sure. These are the lines I added/edited from the MultiBeast 4.5.1 Core i5/i7 Overclocking file. Notice the change in the Name (APSS, Package (0x1E), 0x1E = 30 total P-states in APSS (as opposed to the original 27); This added 3 P-states (3 additional 'Package (0x06)') up to 4.5Mhz. First time I've edited a SSDT file, so you've been warned.

Name (APSS, Package (0x1E)
        {
            Package (0x06)
            {
                0x1194,
                0x000493E0,
                0x0A,
                0x0A,
                0x2D00,
                0x2D00
            }, 
            Package (0x06)
            {
                0x1130, 
                0x000493E0, 
                0x0A, 
                0x0A, 
                0x2C00, 
                0x2C00
            }, 
            Package (0x06)
            {
                0x10CC, 
                0x000493E0, 
                0x0A, 
                0x0A, 
                0x2B00, 
                0x2B00
            },
