Hi all,

I have a i7 2600K Sandy Bridge CPU / Asus P8P67 Pro machine. I got Monterey 12.2 working on following this guide here.

However when I updated to 12.3 I found that power management no longer worked. I was stuck at the lowest MH state (1.6). I ended up having to roll back the update (by reinstalling).

I did find one other person who had this issue when searching "opencore sandybridge power management monterey", but no solution unfortunately. Does anyone have any suggestions on how to fix this?

Thanks!
 
No. I'm stuck on 12.2 for now. I think I may revert to Big Sur. Looks like the end of the line for Sandy Bridge. Served me well for 10+ yrs.
 
Hello guys, i had the same problem after installing 12.5, everything worked slow.
i found the solution ,maybe it will help you.

config.plist->Quirks->DummyPowerManagment = true

Also some people change, but i haven't such option in my plist
config.plist->Quirks->IgnoreInvalidFlexRatio = true

After that i carefully following CPU temperature:
without load it is around 45-50
with load it is around 65-70
 
I have used ASPP-Override.kext and that seems to be working for me.

I did post links yesterday, but it appears that despite being a member here since forever, my post was deleted.

The forum rules apply to everyone - Length of membership is irrelevant.
 
DummyPowerManagment will disable power management so you are basically running at full throttle all the time. Not ideal.

What does ASPP-Override.kext do?
 
Has anyone tried SMBIOS MacPro6,1 by any chance?

The link that I originally posed describes what happens - basically the problem with 12.3 is that Apple changed the way that the power management scheme is recognized to be more based on the CPU. ASPP-Override effectively reverts that change

Thanks for that. Is it possible for you to repost without the links? I can search google for more information with the keywords to try to reverse engineer the links. So I understand correctly, you are saying speedstep is actually working for you then?

Also did you simply add this kext, or was there any extra configuration required?
