Enable sleep for Asrock B75 Pro3 M?

Hello.
I am using Asrock B75 Pro3-M. Asrock B75 Pro3 is currently the most popular mainboard in Korea (according to Danawa.com). The difference between Pro3 and Pro3-M is that Pro3 is ATX while Pro3 M is Micro-ATX. Other than that, I believe they are identical.

I installed Mountain Lion on this and everything worked without much effort, except sleeping and power management. It looks the CPU is running at full speed all the time and it does not wake from sleep.

I already patched the BIOS, but I could not find any information to enable sleep for this mainboard. I tried sleepenabler, or patched Apple Intel CPU Management kext or something, none of them worked. I extracted DSDT myself, but I do not know where to edit to enable sleep. Could someone help me? Given this mainboard's popularity, your help will benefit many people. Thank you.

Complete build info and also update your profile with it.

Hello.
I do not know what build information are needed but as far as I know,
CPU: i5-3570K Ivy Bridge,
RAM: Samsung DDR3-12800 4GB * 4 =16GB
Mainboard: Asrock B75 Pro3-M
SSD: Mach Fusion 256GB
Grahics: onboard
Ethernet: onboard
Sound: onboard
Monitor : Dell 24 inch through DVI
and a keyboard and a mouse. That's basically everything, there are no optical drives, no PCI-ex cards, no HDDs, etc.

I updated the information. Does the modification to the DSDT differ according to CPU or other peripherals?
Any ways, I am willing to buy another B75 Micro-ATX mainboard, if it everything works on that mainboard. I looked at the DSDT database but the mainboards listed there seemed to be old.

Does the modification to the DSDT differ according to CPU or other peripherals?

Yes it does, beside according to the forum rules you need to update your profile with hardware information.

If you have not flashed the BIOS with patched BIOS then suggest you do it > http://biosrepo.wordpress.com/asrock/b75/

More info about flashing BIOS > http://www.tonymacx86.com/dsdt/47397-msi-asrock-foxconn-1155-patched-bios-thread.html

Latest BIOS available for that motherboard is 1.6 and the patched BIOS is 1.5. I am not sure what version of BIOS you are currently on.
If in future you decide to update the BIOS, you have to extract and edit a new DSDT again.


Reset the BIOS to factory settings and make these changes.

Advance > Advanced\North Bridge Configuration
Primary Graphics Adapter > Onboard*
Share Memory > 64MB*
Render Standby > Disabled*

Advanced\South Bridge configuration
Deep Sleep > Enabled in S5*

Advanced Storage Configuration
SATA Mode > AHCI*
Hard disk SMART > Enabled*

ADvanced\Super IO config > Serial Port - Disable

Advanced ACPI conf
Suspend to RAM > Disabled*
ACPI HPET Table > Enabled*
RTC Alarm power on > by OS*
reset of the option here is disabled.

Not so imp settings but runs the system quite. Once you boot in fans are controlled by OSX.
HW Monitor
CPU FAN > Level 2
Chassis fan settings > Level 4


Do a fresh installation download the attached DSDT unzip it and keep it on the desktop.
Download latest Multibeast for ML and run it with the below options checked.

Thank you very much for spending your time on helping me. I am afraid that I have to say that it did not work. I had already flashed the patched ROM 1.5 from that web site you wrote above. I followed your settings, I even reinstall Mountain Lion again, but after awaken from sleep the 'waiting circle' endlessly revolved and the system was not responding. Also during idle, the power consumption was about 10W higher than idle on Windows. I guess power management also did not work.

Maybe sleep does not work on this board no matter what. Probably I would better looking for another Ivy Bridge Micro-ATX board that works.

Thank you again for helping me.

Try changing the SMBIOS to iMac 12.2 and see if that makes any difference.

Unfortunately, it did not work.

Hi to everyone! I am a newbie in Hackintosh world...Three weeks ago I bought a pc mounting an Asrock b75m GL r2 (with a modded bios v. 1.2 - thanks to Samisnake!), a 3770 Ivy Bridge CPU, an Nvidia GTX 650 and ML 10.8.2 . I could say that almost anything is working except for wake from sleep(it is very slow and sometimes it causes my rig to be irresponsive except for my keybord and mouse as well as to close the running apps) and for the recognition of my ethernet when I unplug it during use (when I roboot, it is recognized again). Maybe I'd need to modify my DSDT...any suggestion would be VERY appreciated from MiniITX and any other expert skilled in solving this kind of issues.
Thanks in advance.

cris, as you can see above the wake from sleep did not work for typingcat.

You are on a different BIOS version so lets try the DSDT solution.

Download the tool DSDT Editor > http://www.tonymacx86.com/dsdt/31716-guide-creating-your-own-dsdt-most-boards.html
Extract the DSDT save it as .dsl file (4th option on file tab) compress it and attach.

Hy MiniITX! So quick... Thanks a LOT ! ok... I hope I did it right...
