SSDT generation script (Ivybridge PM)

[philip_petev]

Pike, I'd like to ask you for permission to include your SSDT generator script in the HP ProBook Installer. Thank you in advance.

- Fresh 10.8.3 install
- changed SysDef into MacMini 6,2, and NO NEED ssdt anymore:

intel core i7 3770T
MSRDumper

Mar 15 15:20:33 localhost kernel[0]: MSRDumper CoreMulti(16) 
Mar 15 15:20:33 localhost kernel[0]: MSRDumper PStatesReached: 16 17 21 25 31 32 33 34 35 38 40

Thanks anyway to PikeRAlpha and Jeroen for your great work!

Sure. No problem.

But then you don't use Ivy bridge low power management, but the old school PM.

I'm sorry, Pike, don't understand: could you be more specific?

Meanwhile, I tried the script, and it works as always.

SMRDumper it's pretty much the same of the one posted before

Mar 15 18:29:07 localhost kernel[0]: MSRDumper CoreMulti(16) 
Mar 15 18:29:07 localhost kernel[0]: MSRDumper PStatesReached: 16 17 21 25 31 32 33 34 35 38 40

What am I missing?

hey guys what does the amount of p states vary on i see francis you get a lot from your 3770t but i have a 3770k oc to 4500 only get six p states what does it depend on thanks

IvyBridge PM let's you run your system more efficiently. At a lower than factory specified TDP, which almost always results in a higher temperature rating. For example. I am running a 95 Watt i5-2500K at 90 Watt without any issues. Resulting in a 3-5 centigrade drop.

You could try something less than the factory specified 45 Watt TDP for your CPU and monitor the temperature before and afterwards. But be careful with OC'ed setups.

That depends on the CPU and model identifier and possibly the UEFI's PM implementation. Not to mention that the 3770T is more power efficient, running at a much lower clock speed of 2.5 GHz (more like the Apple used CPU's).

so six p states is pretty much ill im gonna get out of the 3770k with the 4500 over clock

Yup.
