Wrong frequency after install speedstep kext

[Ta Luan]

Hi Mercurysquad, I install the speedstep 1.4 on my lap Dell M6300 (Itakos 4i/9.2 kernel) , everything work fine but my CPU (T7500) speed info in about Mac display a stranger frequency ( 4.30 GHz ) How to fix it ?

[frantisheq]

same here with E6600. it shows 4.30GHz instead of 2.4

[mercurysquad]

Can you please post the output of

 

sysctl hw | grep frequency

 

and

 

sysctl -a | grep throttle

Thanks Mer! I've up to 10.5.5 from Apple , sleep work ok but this issues still there.

My Sysctl hw grep :

 

hw.tbfrequency: 1000000000

hw.cpufrequency_max: -2094967296

hw.cpufrequency_min: 800000000

hw.cpufrequency: 1456000000

hw.busfrequency_max: 800000000

hw.busfrequency_min: 800000000

hw.busfrequency: 800000000

hw.busfrequency = 800000000

hw.cpufrequency = 2200000000

hw.tbfrequency = 1000000000

 

Sysctl -a grep throttle :

 

kern.exec: unknown type returned

kern.cputhrottle_curfreq: 2200

kern.cputhrottle_curvolt: 1388

kern.cputhrottle_freqs: 800 1200 1600 2200

kern.cputhrottle_factoryvolts: 876 988 1148 1388

kern.cputhrottle_ctl: 2859

kern.cputhrottle_auto: 1

kern.cputhrottle_targetload: 30

Look.

It is a problem of IntelSpeedStep only. After it replacing by other driver all is OK.

I know, I'm working on it.

Had the same problem, the DSDT + SMBIOS Chameleon fixed it, I have T7250, so 2Ghz.

 

 

Into SystemConfiguration/com.apple.Boot.plist

 

		<key>SMexternalclock</key>
	<string>200</string>
	<key>SMmaximalclock</key>
	<string>2000</string>

It not help me. Only way is to delete IntelSpeedStep.
