Mavericks - only ONE pstate available??

[cosjef]

My CPU fan never ramps down in speed, despite having enabled EIST and C3/C6 in BIOS. I have a
Gigabyte Z68X-UD3H-B3 motherboard running an overclocked Sandy Bridge i7 CPU.

Here is what I see:

$ sysctl hw | grep cpufr
hw.cpufrequency: 3492000000
hw.cpufrequency_min: 3492000000
hw.cpufrequency_max: 3492000000
hw.cpufrequency = 3492000000
hw.cpufrequency = 3492000000

The MSRDumper kext yields this:
kernel[0]: MSRDumper CoreMulti(35)
kernel[0]: MSRDumper PStatesReached: 35


I performed a DSDT install (Bios v12) and used "Sandy Bridge Core i5/i7 Overclocked" for SSDT options and Mac Pro 3,1 as my System Definition.

I have no idea why no other PStates are showing up. From other posts, I should be seeing 8, 35, 36, 37. Any ideas?

What SMbios are you running? Also, have you tried making your own SSDT?

Silly question, but how do I check the SMBIOS in use? Here's what is in the SMBIOS.plist file:

<dict>
<key>SMfamily</key>
<string>Macmini</string>
<key>SMproductname</key>
<string>Macmini5,1</string>
<key>SMboardproduct</key>
<string>Mac-8ED6AF5B48C039E1</string>
<key>SMserial</key>
<string>C02H5YH3DJD0</string>
<key>SMbiosversion</key>
<string>MultiBeast.tonymacx86.com</string>
</dict>

According to that MacMini is your system definition.

Also, you dont mention the exact model CPU you are using, but Sandybridge and Z68; the closest hardware definition to that is iMac12,1 or 12,2 for an i7 chip.

You should consider something closer to your hardware spec.

Sorry, the CPU is an Intel(R) Core(TM) i7-2600K CPU @ 3.40GHz

I'll try those two system definitions next.
