[Guide] Asus P8Z68-VPro with SpeedStep, Turbo & Sleep

[nmaia]

Thanks Francis for the reply.

I will probably make a fresh install on a separate disk and check the results.

Will try it next weekend, then Ill post my results.

I've been playing with this for a while tonight and all I get is:

MSRDumper CoreMulti(16) 
MSRDumper PStatesReached: 16

I'm just following the first post in the thread, with some troubleshooting based on what TwoSixy says here: viewtopic.php?p=140770#p140770

Thoughts? Could it be because I have the 2500K?

On the plus side, sleep seems to work

Thanks so much for the troubleshooting steps TooSixy. I went through step by step and most everything was OK except for my BIOS setup.

I think that my BIOS wasn't set up properly, but I think I have it (at least partially) working now.

I now get:

MSRDumper CoreMulti(37) 
MSRDumper PStatesReached: 16 37

So, I think I'm getting two states now. Could this be because I'm setting "All Cores" in the Bios (i.e. it scales all cores together)?

Hi Betelgeuse,

Yes it scales to the only state you have for all cores.

If you set it to something like 40, 39, 38, 37 you will have those states in the MSRDumper.
But remember that you have to "stress" the CPU, otherwise MSRDumper only shows the higher state that the CPU achieved.

One thing I don't understand and maybe someone can explain is why in all posts everyone suggests to set it "for core" and with different ratio.
Why not set all cores for the same ratio?

I ask this because i've set it with 47,47,47,47 and my scores are higher and it works fine.

Anyone?

This is an interesting conversation. I will be staying tuned for this. On my i7 870 I ran an all-the-time overclock at 4 GHz. It was cooled by a Corsair H70 but ran warm enough to heat my master suite (maybe a slight exaggeration). I am interested in the SpeedStep method of utilizing the overclock when necessary. I use my system for HD to AppleTV media encoding and school work, so a constant overclock isn't necessary.

Once your system boots fine under 10.6.7, comes the interesting part.

Is that 10.6.7 combo update, or 10.6.7 for iMac early 2011 update (which you install when you change your system to be an imac12,2) ?

Specs:
P8Z68-V Pro
i7 2600K
4gb G.Skill Ripjaw (have 8GB, but only 4GB actually sitting in the machine)
GTX 460

EDIT:
Installed from 10.6.3 disk, did combo update to 10.6.7, then did multibeast (with nvidia drivers) and bridge helper. Did all the steps in this thread. I did come across only being able to find AppleLPC.kext in the /S/L/E/ folder, not in the 10.6.7 iMac early update though.

Currently getting scores of
GeekBench: 12000ish
Cinebnech GPU: 35.11fps
Cinebench CPU: 7.31pts

I am still getting

MSRDumper CoreMulti(16)
MSRDumper PStatesReached: 16 38

though... Will double check BIOS settings.

EDIT2: Put Turbo for cores onto auto, now I can get this,

MSRDumper CoreMulti(35)
MSRDumper PStatesReached: 16 26 34 35

and thats running cinebench CPU, but now it gave me a 6.79. The jerk....

Here is what I've on my UEFI BIOS .. this works..

Hi all.

Finally I managed to get Sleep to work.

My steps were (hope I don't forget anything)

- Fresh install using iBoot Legacy 2.7.2 with 4Gb of Ram and boot with PCIRootUID=1
- 10.6.7 Combo Update - Don't restart
- Bridge Helper - Don't restart
- Multibeast 3.7.2 - Options: Easybeast + System Utilities + Realtek ALC8xxHDA + AppleHDA Rollback + ALC892 + ATI 1.6.34.13 + hnak's AppleIntelE1000e Ethernet.
-Reboot

Now the important:

Then I followed every Francis steps from 1st post on this thread but with one big difference.
I got the needed files, using pacifist, from the final 10.6.8 Combo Update and not from the "earlyiMac update".

The only file that used that was not from the final 10.6.8 Combo Update was "iMac12_2.plist" that I got from a forum member (thanks).

I've also edited /E/smbios.plist and changed it from "MacPro3,1" to "iMac12,2"

Rebuild permissions and reboot.

That's it. At least for me.

Hope it helps

I finally got some time to try this out on my backup build.

i got as far as updating the 'mach_kernel'..I'm stuck, how do I update the mach_kernel?

 

[SoundFu]

Thanks thats a pretty lengthy process and probably why just deleting the old one and adding the new one didn't work lol.

No problem as that was my old backup test installation. Im now going to use the combo update 10.6.8 followed by multibeast 3.7.3 (no more bridgehelper needed).
And then back that installation up before messing with anything again.
