C-States P-States for i7-3770k ?

[EvgeniX]

does it work for some one?

 

I use iMac13,2 SMBios with:

	<key>ACPI</key>
	<dict>
		<key>DropOemSSDT</key>
		<false/>
		<key>GenerateCStates</key>
		<true/>
		<key>GenerateIvyStates</key>
		<true/>
		<key>GeneratePStates</key>
		<true/>
	</dict>

and only have 16,47 

 

any help?

Download a custom SSDT.aml for ur cpu. Google it

I have a 3570k overclocked to 4.6Ghz and I dont even get that mine is stuck at 46 wont throttle down. Oddly enough my temps are 8-10c cooler in 10.9 then in 10.8.4 with the the two (16 - 46) and my geek bench is higher? I also am using a standard 7200 rpm drive instead on the ssd that has my 10.8.4 installed on it. Gotta say i'm impressed!

 

Any thoughts on how to get the cpu to throttle between 16, 46?

SSDT.aml did not helped

While I don't have your CPU, I'm also only getting two states with my i5-2500. I've got the same SSDT and Boot.plist file that I have under 10.8, but I'm not getting speedstep working. Definitely watching this topic.

do you use iMac13.2 SMBios? I change it to Macmini6.2 and have all SpeedStep and a little better performance... 150-200+ in Geekbench

 

with your CPU you can try Macmini5.2....

Use MacPro 3,1 smbios.

 

 

Remove this line: 

<key>DropOemSSDT</key>

Should be used only with a CPU specified SSDT.

 

put these lines: 

        <key>GenerateCStates</key>
        <true/>
        <key>GenerateIvyStates</key>
        <true/>
        <key>GeneratePStates</key>
        <true/>

After check with HWMonitor app or SMC Monitor if voltage, multiplier suffer changes in realtime and freq. increase/decrease! If that happens everything (speed step) is workin' correctly.

 

Install this FakeSMC: http://bitbucket.org/kozlek/hwsensors/downloads

not a good idea since MacPro 3,1 does not have Ivy in originals...

 

also after some read I find out :

 <key>GenerateIvyStates</key>

 

        <true/>

 

equals

 

GeneratePStates = TRUE;

GenerateCStates = TRUE;

EnableISS = FALSE;

PluginType = 1;

DoubleFirstState = FALSE;

DropOemSSDT = TRUE;

C3Latency = 0x3E7;

I have same problem, i5-3570k overclocked 4.2ghz.  It stuck @4.2ghz.

o.c.B.plist

DropSSDT=Yes

GeneratePStates=No

GenerateCStates=No

iMac13.2 just does not support any speed steps...

If you want them use macmini6.2...

So I do not care about them so I'm OK with 13.2

[cochon]

Fix i5-3570K with speedstep. I used MacPro 5.1 in smbios

 

Go to /S/L/E/IOPlatformPluginFamily.kext/Contents/Plugins/X86PlatformPlugin.kext/Contents/Resources

 

Copy Mac-F65AE981FFA204ED.plist Mac-F221BEC8.plist

 

 

After that do this

sudo rm -rf /System/Library/Caches/com.apple.kext.caches/Startup/kernelcache

sudo kextcache -system-prelinked-kernel

sudo kextcache -system-caches

Note: Mac-F65AE981FFA204ED.plist is Macmini6,2 plist and Mac-F221BEC8.plist is my MacPro5,1 board type.

 

Good luck ----

[kermit1219]

so does that essentially that is just replacing the mac pro smbios with the mac mini? why not just use mac mini smbios? (I'm not sure what the difference is here.. I know with the mac mini smbios, I seem to take a performance hit. Would that be the case here?)

 

I'll try it tonight and post my results .. any feedback or clarification would be greatly appreciated.
