Speed Step Only Works After Sleep - Maximus V Gene

[SUCCESS] Speed Step Only Works After Sleep - Maximus V Gene

Hello, I got Sleep/Sstep to work, but speed step only works after sleep. I have no DSDT, but the patched bios for my MB. Do I need a specific Smbios? Or add something to the SSDT/BootPlist? Any help, would well...help. Thanks! i5 2500K @ 4.2Ghz with the appropriate SSDT


EDIT: ANSWER IS LOCATED DEEPER IN THREAD!

Having the same problem with a Maximus IV Gene-Z, worked fine in 10.7.4, now only works (sometimes) after sleep. I'm on patched bios 3203 with DSDT

I'll try different profiles and report back. Anyone have a clue?

Anyone?

Okay, so I'd rather have a PC with Speed-step rather than no PC at all. So I created a script to run at startup that puts my pc to sleep, then I have to manually wake it. But at least speed-step works


If anyone has any advice on how to speed up this loading, by elevating it or whatever. Or to make it auto-wake right after it would be helpful!

Hi KoalaMan,

Have you checked if there is a difference between what kexts are loaded before or after sleep and what the differences are, any clues in the Console? Seems like a really odd problem.....

If that really doesn't help or give a clue then I'd be inclined to extract a DSDT and patch it up anyway to see what happens. I don't mean a standard pre-edited DSDT, but the one that you can pull from your board directly. There are lots of ways to do it and I am sure you know the drill. My all time favourite is DSDTse. Then go through the standard patching process and see if you get any difference.

I use a patched uefi on my Zotac and while I don't need to use a DSDT I found that I didn't get proper powermanagement without one with p-states in it. I also found that patching the AppleIntelCPUPowerManagement.kext with the perl script from Oralia and using that together with the DSDT gives the best results. YMMV of course.....

Maybe, would the Generate P-states help at all?

No idea. I guess it is worth trying.......

Nope. Nothing.

As I stated in another thread, still nothing. Tried all Mac Pro smbios'es and KPed all of them but 3.1.
