10.7.4 Power Management and Sandy Bridge CPUs

It's been a week since the 10.7.4 update, and an issue has cropped up with Core i5 and i7 Sandy Bridge CPUs. As part of this release, Apple updated the power management drivers. These new drivers are effecting performance, as some CPUs are stuck at a 16x multiplier, thus limiting them to a maximum clock speed of 1.6 GHz. When we discovered the issue, we released a temporary workaround on the tonymacx86.com forum while working on a permanent solution. We are now happy to announce our permanent solution.

SpeedStep is a trademark for a series of dynamic frequency scaling technologies built into some Intel microprocessors that allow the clock speed of the processor oto be dynamically changed (to different P-states) by software. This allows the processor to meet the instantaneous performance needs of the operation being performed, while minimizing power draw and heat dissipation. Enhanced Intel SpeedStep is sometimes abbreviated as EIST.

The Secondary System Description Table or SSDT is a continuation of the Differentiated System Description Table, or DSDT, allowing the the motherboard manufacturer or OEM to provide the base support in one table (DSDT) and add smaller system options in other tables (SSDT). As such they use the SSDT to provide speed stepping and power configuration.

The Chimera bootloader will either read the SSDT from the motherboard's BIOS/UEFI, use the SSDTs generated by boot keys provided by the MultiBeast UserDSDT boot.plist, or a user provided SSDT. As part of the 10.7.4 update, some Sandy Bridge Socket 1155 i5/i7 CPUs have issues with the BIOS/UEFI SSDT and need a properly edited one to override its configuration. NOTE: Core i3 and i5-2400 CPUs are known to work properly with the BIOS/UEFI SSDT, and don't need this fix.

In order to make optimization easy for the average user, we've prepared 3 SSDT files, included in MultiBeast 4.5.0. The first is for Core i5 systems running at stock speeds. The next is for Core i7 systems also running at stock speeds. The final one is for over clocked Core i5 or Core i7 systems. The specific SSDT.aml file installs into the /Extra folder and will initiate SpeedStep properly in 10.7.4. One of these optimized SSDTs are recommended for users of the following CPUs: i5-2500, i5-2500K, i5-2550K, i7-2600, i7-2600K, i7-2700K.
After installing one of these SSDTs you can verify that SpeedStep is working on Sandy Bridge CPUs by installing Project OS X's new FakeSMC, FakeSMC Plugins, and HWMonitor app, available in the latest MultiBeast. After installation of these files, launch HWMonitor and click the live cpu Frequencies and Multiplier to view in the menubar as shown below. Keep in mind that Turbo frequencies will not appear.


Special thanks to Greggen and everyone in the community for sharing their knowledge- testing and editing SSDTs in the past week. We're interested in any feedback using these new tools. Please add your comments and results in this thread.


BridgeHelper 4.0 - Enhanced 10.7.4 Kernel for Ivy Bridge CPUs
As part of Apple's commitment to Open Source, they make the current Mac OS X kernel source available about a week after releases at opensource.apple.com. As there are no Ivy Bridge Macs yet, MacMan has added support for Ivy Bridge CPUs to xnu-1699.26.8 (AKA the 11.4.0 Darwin kernel shipped in OS X 10.7.4) and we're happy to announce it's release.

BridgeHelper 4.0 will replace your 10.7.4 system kernel with MacMan's 10.7.4 Darwin kernel with Ivy Bridge CPU support. The installer is now available at tonymacx86.com/downloads.

PLEASE NOTE:  Ivy Bridge CPUs and chipsets are not currently supported natively by Mac OS X. We can't recommend Ivy Bridge systems yet, as there is no official support. Hence, please don't view this as buying advice. We don't recommend using a patched kernel for the long-term. The vanilla kernel is a much more desirable solution for a stable system.

iAtkos 10.7.4 with Multibeast 4.4 [UPDATE]


UPHUCK: 50% lower geekbench scores reported (14K to 7K) from 2 machines after updating from 10.7.3. Asus P8Z68 with i7 2600K and P8P67 with i7 2700K. Both have modded bios' using stock cpupowermanagement without disabler. 

Keep 10.7.3 until the mystery is solved.

SECURE UPDATE FOR IATKOS L USERS

What we know about 10.7.4 so far...

Important: 10.7.4 and i5/i7 Sandy Bridge CPUs Temporary Fix 
  • 11.4.0 Darwin kernel
    • No native Ivy Bridge CPU Support
    • Ivy Bridge Users- do not update yet- MacMan will provide a 10.7.4 enhanced kernel
      as soon as the source is released.
  • Improved AMD, Intel, and NVIDIA graphics drivers.
    • If you use customized or edited graphics kexts, it will be necessary to make the edits again using the new drivers as a base. 
    • If you use Combo OpenCL Enabler, reapply it before reboot
  • The update will replace your AppleHDA.kext. 
    • If you use ALC8xxHDA for onboard audio, you will have to reinstall AppleHDA Rollback using MultiBeast before rebooting. 
    • If you use toleda's AppleHDA for onboard audio, you will have to reinstall the Patched AppleHDA using MultiBeast before rebooting. 
    • If you use VoodooHDA, you will not need to make any modifications.
  • If you use Sleepenabler.kext, remove before updating.
  • If you use SpeedStepper for UEFI motherboards, do not update yet- there is a new speedstepper script coming soon.
