NEW Intel P55 Mobos & Core i7 860 / i5 750 CPU LGA1156

snokarver · November 27, 2009

AppleHDA.kext of MAC OS X 10.6.0 (10.6.1 dosen't update it) in combination with LegacyHDA.kext for ACL889 in extra/extensions folder work without problems, except the flood of error messages by starting the computer. LegacyHDA.kext is not a audio driver, it include only a config file, so it need AppleHDA.kext. I modified my dsdt.aml HDEF section too, not sure whether it is necessary with LegacyHDA.
The use of an older extension and the much errors make me a bit stomachache when I think on the feature updates.

Can you be a bit more specific on the exact files and where/how you installed them? I have the exact same mobo as you but can't seem to get audio working in 10.6.2.

Thanks much.

I have you beat by a hair at 9866. I'm running an i5 OC'd to 3.67 at stock voltage as well. Are you doing anything special to get your temps that low? I installed a massive Freezer 7 heatsink and 2 extra case fans but am still staying in the high 60's to low 70's in Prime95. BTW the new i7 iMacs are only scoring 9638 on Geekbench so big win to us overclockers!

http://browse.geekbench.ca/geekbench2/view/191371

This is my new score which is Prime& linx stable. It's running at 3,78 GHz (seems like the Hackintosh is reading my BCLK of 180 MHz x20 but I chose the x21 multiplicator. RAM is running at 1440 MHz.

In BIOS you shouldn't choose Load Line Calibration (higher temperatures, normally not necessary and against Intel Specs) but DVID. DVID allows to lower the Vcore in idle situations. I have now 1 V idle and 1,25 V at full load (Windows 7 CPU-Z values, almost the same in the BIOS) I chose the normal 1,15 V and for DVID +0,15 V so at load I'll get not 1,3 but 1,25 V. Under that value it doesn't run stable. Temperatures @idle: 30-34 °C @full BOINC load: 57 °C max. @ full linx load in Windows 7: 66 °C

My heatsink is the very popular Prolimatech Megahalems with a Scythe 1200 UPM fan. (quite quiet )

Good to hear you got the issue solved! Just put up a few new posts- including a dual boot guide for Windows 7 and Snow Leopard.

Happy Thanksgiving everyone.

I just wanted to repost a small part of the dual-boot guide here, since it bit me when I was installing SL, and I thought it might help others as well. My USB flash drive is considered a hard drive by the BIOS, so this needs to be done in order to ensure booting from it.

Go to CMOS Setup Utility and choose Advanced BIOS Features.
Select Hard Disk Boot Priority.
Move your Chameleon USB drive to top of list.

So the ALC889.zip contains all what I use for audio. You will really need the /Extra/Extensions/LegacyHDA.kext from zipfile. Than, you must enable the stock AppleHDA.kext from 10.6.0 or 10.6.1 (is the same). If you don't have it, use it from zipfile in attachment. If you don't get sound after rebuilding kext cache (booting with "-f" option), you must modify your dsdt table. I provided mine, but I noticed than the dsdt table contains processor specific information too, and you have not the same CPU. At last, don't try overwriting the whole folders, Finder delete the whole content in destination folder before copying the new content (Windows Explorer does this not). So move only the files, not the folders.

Can anyone confirm the optic audio output on the P55M-UD2 is working flawlessly?

It's quite important in my HTPC setup, so I need a definitive answer...

Thanks!

Here is a fix for DSDT for HPET ( no more need for NullCPUPM.kext ) on GA-P55-UD4, Bios version F3.

Not tested on others.

Original Code:

Device (HPET)
			{
				Name (_HID, EisaId ("PNP0103"))
				Name (ATT3, ResourceTemplate ()
				{
					IRQNoFlags ()
						{0}
					IRQNoFlags ()
						{8}
					Memory32Fixed (ReadWrite,
						0xFED00000,		 // Address Base
						0x00000400,		 // Address Length
						)
				})
				Name (ATT4, ResourceTemplate ()
				{
				})
				Method (_STA, 0, NotSerialized)
				{
					If (LGreaterEqual (OSFX, 0x03))
					{
						If (HPTF)
						{
							Return (0x0F)
						}
						Else
						{
							Return (0x00)
						}
					}
					Else
					{
						Return (0x00)
					}
				}

				Method (_CRS, 0, NotSerialized)
				{
					If (LGreaterEqual (OSFX, 0x03))
					{
						If (HPTF)
						{
							Return (ATT3)
						}
						Else
						{
							Return (ATT4)
						}
					}
					Else
					{
						Return (ATT4)
					}
				}
			}

Fixed Code:

Device (HPET)
			{
				Name (_HID, EisaId ("PNP0103"))
				Name (ATT3, ResourceTemplate ()
				{
					IRQNoFlags ()
						{0}
					IRQNoFlags ()
						{8}
					Memory32Fixed (ReadWrite,
						0xFED00000,		 // Address Base
						0x00000400,		 // Address Length
						)
				})
				Name (ATT4, ResourceTemplate ()
				{
				})
				Method (_STA, 0, NotSerialized)
				{
					Return (0x0F)
				}

				Method (_CRS, 0, NotSerialized)
				{
					Return (ATT3)
				}
			}

I tried to replace the HPET section in my DSDT.aml with your code, but compiling returned the following errors:

"Intel ACPI Component Architecture

ASL Optimizing Compiler version 20090730 [Aug 12 2009]

Supports ACPI Specification Revision 4.0

I can 100% confirm that optical out IS working on the UD2 with tonymac's install. I have tested it with a 10 m optical cable on my rig to my YAMAHA RVX 565, works absolutely beutiful.

Can anyone confirm the optic audio output on the P55M-UD2 is working flawlessly?
It's quite important in my HTPC setup, so I need a definitive answer...

Thanks!

dorkiaa · November 27, 2009

thanks theotherone! one bad ass receiver you've got there

two more questions:

- If I have one 500GB drive and two 1TB drives, can I use RAID 1 on the two 1TB drives and leave the 500GB as is (with the OS in it)?

- Has anyone tried the new F5 P55M-UD2 BIOS?

Hey guys, I have been running SL on my new system for a couple of weeks now and so far I have been VERY happy with the results I'm getting. I want to thank everybody for their help on this forum, you guys are awesome! I wanted to see if any of you guys might have any ideas for a couple of minor issues I'm running into.

1. Has anybody found a way to get accurate CPU temps reported in SL for all 4 cores with an i5? I used the new FakeSMC from Netkas but it only shows CPU A in iStat.

2. This may be a little off topic but I'm dual booting Win7 on a seperate hard drive and am having Bluetooth pairing issues w/ my Apple keyboard and mouse. Everytime I reboot to the other OS I'm having to re-pair both devices and there does not appear to be a way to disable the BT passkey for either OS. It's getting annoying to have to break out a wired keyboard and mouse everytime I need to boot to Windows.

Any ideas would be greatly appreciated!

theotherone · November 28, 2009

I don't know if onboard-sata is working, probably not, haven't tested it.

The new BIOS F5 is working for me (loaded it an hour ago), so, my rig started after setting bios back to AHCI, couldn't tell more, time will tell...

… but i cant get the audio working. is this because i have the Realtek 889A compared to tonymacx86's 888B? i tried installing the 10.6.1 AppleHDA as in the retail guide, but after a reboot no sound. so i tried disabling AppleHDA by adding ".bak" on the end of and then tried reinstalling the Legacy 888A kext again. but now i get a kernel panic on boot.

how do i boot back in and get sound working on a UD4P with the Realtek 889A? thanks

anyone know how to fix this? really dont want to reinstall as ive already done it about 4 times and just migrated all my data over as i thought id finally got it working

At last, don't try overwriting the whole folders, Finder delete the whole content in destination folder before copying the new content (Windows Explorer does this not). So move only the files, not the folders.

On the GA-P55-UD4P I had good luck getting sound to work with the VooDooHDA.kext without having to modify Tonymac's DSDT file.

Is there an advantage in using AppleHDA over VooDooHDA?

Thanks much. I deleted my old audio kexts, dropped yours in, then ran Kext Utility to properly rebuild the caches. Still no go. Maybe it's related to the DSDT table but I'll have to go figure out how to work on that. Plain text stuff I can handle, but not this.

Anyone else have a system with ALC889A audio and an i5 where audio is working under 10.6.2? I tried VoodooHDA and it didn't work. Maybe there was a conflict.

aushack · November 28, 2009

doing a reinstall, had no idea how to fix my mess and i guess noone else did either. oh well.

just a tip i found if no one has peaked into the Chameleon help file yet:

type "Graphics Mode"="1920x1200x32" (or whatever your res is) and "Legacy Logo"=Yes into Chameleon or add it to com.apple.boot.plist and remove the "-v" kernel flag and the boot screen will be at full res with the default apple logo so it looks like a real mac booting, still not as crisp, but looks ok. it also gives more room for text in Darwin when booting in verbose.

My heatsink is the very popular Prolimatech Megahalems with a Scythe 1200 UPM fan. (quite quiet )

Thanks for the info, I'm still a noob at this overclocking thing. I'm not able to get anywhere near that temp wise but I was able to get my Geekbench score up to 10,253 with the voltage set at 1.25, BIOS says it's running at 3.88GHz. I'm not far off to Intel specs temp wise though so I'm not too worried. I have my BCLK set to 185, multiplier set to 20 and turbo on which is giving me 21x, RAM multiplier set to 8 I believe and also have memory performance enhance set to extreme. RAM is running at 1480. I think most other settings are at auto, ran stable for over an hour on Prime95 but have not had time to test it longer. Probably won't try pushing it any farther without some better cooling though.

So far GA-P55-UD5 889a is not working for me either, here is what I've tried.

1) Edited DSDT for 889a (see below)

2) Installed LegacyHDA.kext for 889a 4outs2ins HDA headphone in /Extra/Extensions

3) 10.6.2 AppleHDA.kext 1.7.9a4

4) No other changes

ive just tried using using LegacyHDA and AppleHDA 1.7.4a1 (from tonymacx86) and couldnt get it working. havent tried editing the DSDT yet i have no idea how, will have to read up on it.

i guess i could try Voodoo for the moment but ive read it isnt as good as LegacyHDA and the front ports dont work.

Anywhere in the dsdt.dsl, you will find an entry, AZAL that must replaced with HDEF too.

And don't forget to turn on Azalia-codec in bios.

has anyone had a problem with kernel_task taking up 100% CPU? it causes a core to max out increasing the CPU temp and makes the blue login screen take a lot longer to load to the desktop.

last time this disappeared after updating to 10.6.2, but after reinstalling from kernel panicking on boot its still 100% after 10.6.2? anyone know how to fix this?

EDIT: Its ok! spoke a bit too soon. just had to set my BIOS to defaults then put AHCI back on for the Gigabyte ports. ill leave this up just in case someone else stumbles across this problem.

just need to work out audio, Intel P55 sata ports, sleep and make my CPU appear as an i5 instead of a Xeon and everything will be perfect!

When you say appear as a Xeon where exactly does it appear as a Xeon?
