This is a kext correcting certain issues at userspace level. At this moment it is only interesting for Ivy owners and newer.

It is likely reasonable to collect some stats with hardware reports (which ones worked ok, which ones failed). Please use the following format: CPU Model, GPU Model, IGPU Model (including ig-platform-id), OS X version.

How to check your CPU's SpeedStep more simple and more accurate? Use MSRDumper.kext? isata menus?
Maybe you have other ways, but I like to do it myself. So I created this application—"CPU-S". It is very simple to use—Just open the application, click the button, then you get the information you want. I can't wait to share it with you. And here are some screenshots:
click "SpeedStep Test" to check your CPU's speedstep

build and copy ssdt.aml to your desktop
Some drivers need to make the app running. If your system does not have these drivers, the application will install them.

I've been trying to get Speedstep working on my Intel Core i7 870 (Lynnfield) with no success. I've modified my DSDT with some patches and now I've got different multipliers in every core (x9, x22, x23, x24, x26, I think), but I also want to get working the other multipliers (x11, x17... etc) like in Windows.
I've OS X 10.11.6 and Clover 3676. I use the last version of FakeSMC with its plugins. I've attached my DSDT, IOReg copy and my Clover config.plist.
Hi, After a successful installation of 10.10.5 on my x99 system there are still things to fix on post.
I would appreciate every one's help and contribution to solve these problems.
Needing to be fixed:
Sleep/Wake (It doesn't sleep properly and doesn't wake up through mouse touch or keyboard)
ThunderboltEX II isn't recognized being the great mystery of this build (devices are always plugged before booting, Bios Security ID is set to Legacy, the card is installed on Pcie x4_1 and recognized in Windows) AppleThunderboltNHI.kext was removed for faster booting
Speedstep not accomplished
Nvidia Driver - I can't select it at system preferences. OSX default driver assumes control. One of my software's displays the message "NO CUDA ACCELERATION HARDWARE DETECTED".
