CPU (G3258) Stuck on Lowest Multiplier

[BreBo]

If anyone else with a G3258 and a H81M-P33 reads this, I would love to hear your boot flags/FakeCPUID/SSDT settings.

Did you try this guide already?

 

[palmer007]

thats the guide i used

 

[GeneralTau]

Yup, I tried that guide. I can make the SSDT no problem but the CPUID he uses is not bootable for me. I think it might be because he did it on 10.10 and I am on 10.11

 

[GeneralTau]

Are you on 10.11, Palmer?

 

[palmer007]

yes 10.11.4

 

[GeneralTau]

I can not imagine wtf I am doing wrong then. I wish I had time to tinker more but I have exams this month

 

[palmer007]

try

''let gIvyWorkAround=-1'' also try 2 or 3

Hi GeneralTau,

I've got a G3258 build as well, working great since my last clean install of 10.11.3 a few months ago. On 10.11.5 right now with no problems, speedstep working perfectly.

I used the config.plist ONLY from the InsanelyMac post mentioned earlier. Created a Unibeast USB with standard EFI settings on the Clover installation, and dropped in the config.plist and necessary kexts and was good to go with the plist's boot args in addition to nv_disbale=1. The CPUID in that config.plist is the best one to use on this CPU as far as I can tell.
