Need Help with ASUS Board Overclock not working

[Extra2]

Hi Guys, I as wondering if anyone using ASUS Z77 boards could give some advice / Tips to help activating over clocking on Mountain Lion?


Windows over clocking works totally perfectly. Tonymac overclock does not show up though different geekbench scores and system profiler.


Everything was fine with Snow leopard and the over clock was showing.


I tried using a special bios from biosrepro and removing NullCPUPowerManagement.kext but the clock setting would not stick sometimes for both mac and windows (was fine at 4.4 for a month but then capped out at 3.9 after a power outage). it seemed like an unstable BIOS




I now have the most recent Normal Bios for My board but still no overclock. Any ideas?



My system: ASUS p8z77-le plus , 3770K, saphire 6870

Is OSX giving you a higher geekbench result? Sometimes the oc clockspeed is just not displayed.
Have you used a DSDT? Maybe that will help.

OSX is not Giving a higher geek bench result when I over clock. (it does however on windows)

I have tried now with a DSDT and was able to remove the NullCPUPowerManagement.kext and boot without panics, but still no overclock is showing?

I also tried with a SSDT created using MaciASL adn placing in the Extra folder. No luck.

I have also recently tried with hyper threading on and off, and also disabling c-state in the bios. No luck.

Could it be a bios setting I'm missing?

Where is it not shown? Because in the OSX informations are just the stock speeds saved.
I can see my clock speed changing in HWMonitor.

Not shown anywhere in OSX. I have the latest HWmonitor installed, nothing there either, not in system profiler either. Also as mentioned no geekbench difference.

I did mine today. Ended up having to disable EIST in BIOS to get M.L to actually see it and increase geedbench. My system still scales up\down to 1600 when 4200 isn't needed. Maybe try that, you can always change it back.

I tried with Speed Step disabled, and enabled no luck.

So far I have tried:

Speed step disabled and enabled
Hypertheading disabled and enabled

With DSDT.aml in extras folder
With SSDT.aml in extras folder


removing AppleIntelCPUPowerManagement.kext
removing NullCPUPowerManagement.kext

Installing the fakesmc for hardware monitor.

and about all possible combinations of the above .



I'm really scratching my head as to why I am not getting an over clock?

At this stage I am open to all and any suggestions no matter how wild or speculative.


Am I overlooking something obvious like a special overclocking kext or something?


Those with similar motherboard what were your steps?

I have an Asus Maximus V Extreme with an i7-3770K with overclock working and showing in iStat and HWMonitor as 4.4GHz. About This Mac shows only 3.5GHz. At one time when I had a Gigabyte mobo for a few days I got OSX to show 4.5GHz in About This Mac, but I'm not sure how and the setting/options in the Asus BIOS are different.

I was having similar issues with BIOS 1604 download from the repo and the overclock showing sometimes and not showing others. It was all over the place and sometimes the BIOS settings would change on there own. So I downloaded the latest BIOS 1802 and patched it with PMPatch and everything has been perfect since then.

After that, here's how I got mine going.... (some of my settings and things I've done may not apply to you)
-------------------------------------------------------------------------------------------------------

Press F5 to load Optimized Defaults. Save settings and restart. Go back into BIOS settings.

Make SSDT

Run ssdtPRGen. This will install ssdtPRGen.command and an alias for ssdtPRGen.sh in the user home folder.
Open Terminal
Drag ssdtPRGen.command to the Terminal window and add "'i7-3770K' 4400" to it so it's like:
/Users/username/ssdtPRGen.command 'i7-3770K' 4400
Press enter. Enter password. Answer no to not copy to the Extra folder.
Rename ssdt_pr.aml on the desktop to SSDT.aml and move to the Extra folder.
Move ssdt_pr.dsl on the desktop to the trash.
Quit Terminal.


-------------------------------------------------------------------------------------------------------
Make smbios.plist.


Open Chameleon Wizard
Click SMBIOS tab
Click Edit button
Under Premade SMBIOS, select iMac12,2
Click the two Random buttons a few times
Click Save and Quit.

Restart. You should be overclocked.

-------------------------------------------------------------------------------------------------------

Note that you can choose whatever overclock you want, you just need to make sure you put the right frequency in the ssdtPRGen command when you create your SSDT. I actually have multiple SSDT's ready to go so I can change my overclock whenever I want. All I do is replace the SSDT with the appropriate one for the overclock frequency I'm switching to, then restart, go into the BIOS, change the Level Up (4.2, 4.4, or 4.6) or select the Load Gamer's OC Profile (for 4.8GHz), switch back to XMP Profile for my RAM (2400MHz), and check the rest of the settings to make sure they're all still correct. Then start up OS X and all is good.

Also, I did not remove those kexts. No need to since my BIOS is patched. I don't know if sleep works or not. I don't use sleep on my workstation.

Those with similar motherboard what were your steps?

Try leaving speedstep and hyperthreading enabled. only OC the turbo boost setting. try disable EIST. boot without DSDT or SSDT (delete or move them from extra folder) and use boot flag DSDT=null

If you can boot into OSX with those settings, open terminal and type command bdmesg and post to thread. Post to thread, if the CPU still isn't recognized properly try running multi beast with mac mini 6,2 selected and under SSDT select the i7\i5 overclocked processor option...

My setup didn't like that SSDT but yours may?

Different combinations of the above steps will yield different results I found. You might get a kernel panic if you overclock over 4.3 gHz. There is a fix for that but I haven't investigated it yet.

flmmkr and Jet99 Thank you so much for this guidance (flmmkr you could make a real guide with all those concise instructions and I'm grateful), I have worked though both of your suggestions but no luck yet, I'm going to go through both again very carefully step by step and let you know.

My suspicion is the actual bios version blocking it.


Just wanted to let you know I'm working on it.
