I am still trying to get my sound to work properly on an P55 UD4P. I came across this post and was wondering if I need to change my Pinconfigurations section in the DSDT to get them to work. If I use the IOreg utility and look at the HDEF section the Pinconfiguration values are different compared to what I have in my DSDT. Is that normal or do I need to sync them up?

 

Also, how do I determine what value goes where when I am reading this IOREG information. Thx

Your ga-p55-ud4p features an ALC889A different from most of our mobos hda here, you have to bear that in mind before you make any experiment choice.

 

We can try to make it work, here's some recommendations:

First try to modify your dsdt hdef section as follows:

Device (HDEF)
		{
			Name (_ADR, 0x001B0000)
			Method (_PRW, 0, NotSerialized)
			{
				Return (Package (0x02)
				{
					0x0D, 
					0x05
				})
			}

			Method (_DSM, 4, NotSerialized)
			{
				Store (Package (0x08)
					{
						"codec-id", 
						Buffer (0x04)
						{
							0x89, 0x08, 0xEC, 0x10
						}, 

						"layout-id", 
						Buffer (0x04)
						{
							0x0C, 0x00, 0x00, 0x00
						}, 

						"device-type", 
						Buffer (0x11)
						{
							"ALC889a"
						}, 

						"PinConfigurations", 
						Buffer (0x28)
						{
							/* 0000 */	0x50, 0x70, 0x21, 0x01, 0x40, 0x01, 0x13, 0x90, 
							/* 0008 */	0x20, 0x30, 0x81, 0x01, 0x41, 0x40, 0x01, 0x01, 
							/* 0010 */	0x30, 0xE0, 0xC5, 0x01, 0x60, 0xE0, 0x45, 0x01, 
							/* 0018 */	0x0F, 0x00, 0x00, 0x40, 0x0F, 0x00, 0x00, 0x40, 
							/* 0020 */	0x10, 0x01, 0xA0, 0x90, 0x11, 0x01, 0xA0, 0x90
						}
					}, Local0)
				DTGP (Arg0, Arg1, Arg2, Arg3, RefOf (Local0))
				Return (Local0)
			}

			Method (DTGP, 5, NotSerialized)
			{
				If (LEqual (Arg0, Buffer (0x10)
						{
							/* 0000 */	0xC6, 0xB7, 0xB5, 0xA0, 0x18, 0x13, 0x1C, 0x44, 
							/* 0008 */	0xB0, 0xC9, 0xFE, 0x69, 0x5E, 0xAF, 0x94, 0x9B
						}))
				{
					If (LEqual (Arg1, One))
					{
						If (LEqual (Arg2, Zero))
						{
							Store (Buffer (One)
								{
									0x03
								}, Arg4)
							Return (One)
						}

						If (LEqual (Arg2, One))
						{
							Return (One)
						}
					}
				}

				Store (Buffer (One)
					{
						0x00
					}, Arg4)
				Return (Zero)
			}
		}

		Name (BUFA, ResourceTemplate ()
		{
			IRQ (Level, ActiveLow, Shared, )
				{3,4,5,6,7,9,10,11,12,14,15}
		})
		Name (BUFB, ResourceTemplate ()
		{
			IRQ (Level, ActiveLow, Shared, )
				{}
		})
		CreateWordField (BUFB, One, IRQV)

 

Then try this modifcation with vanilla drivers first: you have to experiment at least the green and the black output connectors because sometimes you don't get the sound on the default green connector.

Some reported that they were successful with vanilla kexts and this dsdt change on boards with ALC889A and 10.6.2.

 

Then if it does not suffice, try tony's patched hda drivers suggestions on his blog.

Be careful between each operation, to test all outputs ports (especially green and black) for sound, you don't want to miss a working configuration ...

Here is what I'm thinking of buying, from what I read in the thread this should work well, but I prefer to be sure. For info about what I want to do with it, this will be mostly RAW photo editing (Lightroom) and scientific computations (Matlab).

I'm wondering about the graphic card, this is one with 2 DVI ports and a S-Video : will this work ? Is this not too much if I'm not a big gamer ?

Moreover, I'm wondering where I could spare some money, the two big points being i5 vs i7 and the graphic card.

 

At first I thought about getting an i5 and overclocking. However I'm reading in the last posts all these problems with overclocking and speedstep, and this goes way over my head (I had macs for all my life !). Is it possible to overclock and get performance increases with an i5, and what are the caveats exactly ?

 

Because if overclocking is possible, an OC core i5 could be a better than a stock i7 I guess. Can the i5 be overclocked as much as an i7 ?

 

Sorry for the noob questions, but even if it's cheaper than the apple equivalent, a 900€ order is not that cheap and makes me sweaty ! :P

 

Thanks guys, you amaze me ;) (especially with the DSDT things, I can't grasp how you find what to change !!)

I believe that an UD3R or an UD2 will make it easily as we found quite some experience with these mobos.

The rest depends on what you plan to do with your computer.

I use my computer mostly for software development and music recording with extensive use of real time DSP effects and multitracking, so I decided to buy an i7 because the gain of perfs is only really visible when using heavily multithreaded applications.

By contrast, I bought a fanless nvidia geforce 8400GS oem for $30 with which I am more than happy with and that works afaik 100% with my 10.6.2 system with pcefi10.5/w/cham2rc3, graphicsenabler=y.

Not a gfx specialist but many gfx specialists here tend to agree that ATI is still beta work for osx86 SL, except if you buy one of these expensive ati cards that some of us are using successfully, still I believe the nv gtx 275 of Tony is the smartest performances/price choice today if you need perfs on the gfx subsystem.

Something people might underconsider is often the cpu sink, I use a CNP10X which is by far the most efficient cpu sink I ever bought (running my i7 as I write at 29 deg.C).

I don't recommend to overclock the core i5/i7 family cpus, because they do a good job auto-overclocking themselves securely. I did experiment it and finally moved back to default configuration.

If you have, like me, quite some pro audio equipments (like a high-end fw recording interface), you should also consider a good pcie FW interface. Board with integrated fw did not convinced me a lot when you have to consider performances/latency issues.

Hope this helps.

Hey guys,

 

Thought I'd ask again.... Can I install 10.6.2 on the hard drive I have now and then clone it (via SuperDuper or something else) to an SSD later?

 

My stuff arrives today and I'm getting excited :):P

 

Thanks,

 

Herb

Ok, I followed the latest tonymac's guide and used chameleon , put the bootloader on the hard disk and applied the 10.6.2 update. I managed to get ethernet working before, unfortunately not at 1gbps but working.

 

Now after reboot , when booting from the hard drive, I get the garbled graphics screen. I might probably be able to boot if I use safe mode again but does any one know how to fix this ? I have an ATI 4850 and I've tried with both vga and dvi outputs and using a dvi-vga adapter.

Just add this code to your DSDT replacing the previous HDEF section. Check back on page 33 for Treky's post and download his attachment. Place the LegacyHDA kext in /Extra/Extensions and the AppleHDA he provided in /System/Library/Extensions. Also make sure to remove VoodooHDA if you have it installed. I was wondering if you had gotten your SATA drives to show as built-in/internal in the UD4P without the need of the need of IOAHCIBlockStorageInjector.kext, if so how? Tony's fix doesn't seem to work for my system.

Hi everyone !

 

I just saw that Chameleon 2.0 RC4 is out, in the release notes they say something about i5 detection, but not much more. Have you tried it ? Does it make life easier with P55 boards ?

 

RC4 works without problems in my GA-P55M-UD2/i5.

Processor Speed is now 2,67 instead of 2,70 with i5 modified boot.

In System Profiler there's also a real hardware UUID and not the "000000-0000000-0000800..." entry

I removed PlatformUUID.kext, after Tony's reply above, and Time Machine is still working fine.

Also Geekbench is slightly better (around 7720 compared to 7675 with old i5boot @64bit).

I'm not using GraphicsEnabler=Yes or PCEFI, only NVEnabler, which works fine.

 

It seems that RC4 has minor, but useful, fixes.

How do I install this thing? I only found an archive with some files inside, no installer...

Edit: Turns out I only replaced ATIX2000.kext with the one from 10.6.1

 

For everybody with a 4850 and garbled graphics, I've found that replacing the ATIX2000 and ATI4800Controller kexts with the ones from 10.6.1 and adding a LegacyATI4800 kext works quite well. Not sure what's up with the newer kexts. I meant to narrow this down a little more, but once it was working I kind of forgot about it ;)

There's a readme inside the archive...

Great ! Where can I find them ? You're not talking about kexts from 10.6.0, right ?

 

Any chance you could attach them to a post for easy finding ??? :D Thanks for the help, I'll try to find them and do it.

Jared, just two remarks:

1. You might be interested to test also the Run 1 with no overclocking and see if it's really worth it (with no overclocking u can also set your ram in turbo mode, if you have fast cas memory(7-7-7-21), use the Profile1 option as well)

2. The problem with your test IMHO is that you did not troubleshoot yet why u get {censored} perfs with vanilla power management from the results I read in your previous posts. You should at least get the average imac i5 geekbench results. For instance, my i7 config gives me more or less the average results imac 11,1 core i7, so it's consistent with my hardware system.

1. The "overclock" is using Profile 1 for my memory. There is no way for my memory to run at 1600MHz without the FSB running at 160MHz. I dont see 2.72GHz as being much of an overclock. Especially when the i5 CPU should be running at 2.8GHz when it hits turboboost. Keep in mind that this is 100% configured by the BIOS when I change the memory into Profile1, the fsb goes to 160, and the CPU multiplier goes to 17. I have read that speedstep should be working in Windows at this setting, but I can understand why MacOS wouldn't, hence Run3.

 

2. I am TRYING to troubleshoot why my performance is {censored} using tonymac's current DSDT without NullCPUPowermanagement. Hence Run3. I have asked before for tonymac's BIOS settings (specifically the "Advanced CPU features pane (I have all mine enabled)) but have gotten no reply about that. Just some anicdotes on how geekbench scores will be worse without NullCPU... , well I'm not talking about geekbench I'm talking about real world performance now. As I have said earlier, MSR tools says my CPU is at 1.2ghz or so without any "overclock" at all.

 

I will install the new Chameleon RC4 when I get a chance and see if that helps.

Hi All,

 

I have an i7 860 with a GA-p55-u3dr board with GSkill ripjaws 1600 mhz ram. I had been planning on overclocking my rig until I tried it using the latest DSDT fixes posted for this board to fix sleep. Like Jared, I was having the same terrible performance (GB 32 bit in the 3500 range) when I pulled the patched DSDT.

 

My mobo defaults to a memory multiplier of 10, so with a baseclock of 133, I was getting 1333 mhz on my ram. As a result, I had jacked up my multiplier to 12 and forgot about it. When I started getting the really low scores with the new dsdt, I went ahead and changed the multiplier back to 10. Sure enough, I get 8200 32bit GB score at stock everything.

 

So, am I correct that I cannot deviate with the default bios settings at all without seeing a major dropoff in performance? Why are P55's different when in some of the reading I did on d00d's thread about doing the mac4,1 fix for X58 boards, they were overclocking away?

 

Any ideas or am I missing something?

 

BTW, I also get the high pitched whine when I scroll across windows, etc.

Couldn't get it to work. I tried both ATIX2000 and ATI4800Controller from 10.6.0, from 10.6.1 and then saw your edit and tried X2000 from 10.6.1 and ATI4800 from 10.6.2. Nothing, always get the garbled screen. Can you double-check the version numbers you have on your system?

My BIOS settings were on Auto for Advanced CPU features- I changed them to Enabled, and didn't see any change in performance or Geekbench. So I switched them back to Auto. All I know is I don't overclock, and have never had any GB scores lower than 7000 for the i5. That seems pretty frickin good to me. Hope this helps!

Thank you, what version of the BIOS are you using, I'm using F5 which is the current version.

 

Later today, I'll try using the bios revert to default, and then change what is needed (such as AHCI).

Thank you, GTX 275 is too expensive for me, but I think I'll settle for a 260 GTX, those seem to work while still being quite good. With i5 and UD3R I should be good to go, right ?

No need for FW interface... I'll need a WiFi card though, I have to look at that !

Just tried Chameleon RC4- here are my initial findings:

 

1. Has the Nehalem patch as mentioned in my modified PC-EFI 10.5 post. This enables P55 support without the 'system too fast' issue.

 

2. Breaks GraphicsEnabler-Yes for my GeForce 9400 GT. This works fine with the PC EFI 10.5. I'm pretty sure that PC-EFI recognizes cards better- don't know why yet.

 

3. Still no love for the GA-P55M-UD2 with EthernetBuiltIn=Yes. ;) I still have to use RealtekR1000SL.kext in S/L/E.

 

4. Works without PlatformUUID.kext- no errors with Time Machine or SuperDuper!. I still have to use this kext with PC-EFI 10.5.

 

5. In About this Mac, CPU still Quad-Core Intel Xeon- but with the RC4 the i5 shows up as 2.67 instead of 2.7Ghz.

 

My guess is that netkas will update PC-EFI to 10.6 in the next few days incorporating the changes. What are everyone else's findings?

 

http://tonymacx86.blogspot.com/2009/12/cha...-supported.html

 

Just installed it on my test drive. Will report back later tonight. :)

 

 

Edit: All is good thus far. Had to use the bootflag PciRoot=1 but other than that, seems pretty solid. Graphics seem ok. Will report back after further tests to see if sleep is working...

 

Edit2: System Profiler still states CPU type as Xeon, and now reports RAM speed as 667MHz....

 

Edit3: Sleep is broken. Restarts after wake.

 

Edit4: Went back to Tony's mod'd PC_EFI 10.5

Thank you for the reply. Unfortunately I already have this in my current DSDT and I tried the files on the post by Treky and had no luck to be honest. I suppose I will keep searching....

 

As for the SATA drives. They will only show as internal as long as I have the IOACHI.... in my extra folder. If I take that kext out, the 2 drives that I have connected to the Gigabyte SATA ports(blue), show up as external drives on the desktop. I have not looked at that again to be honest, as I did not think that was causing any issues. Thx

Hey guys,

 

Thought I'd ask again.... Can I install 10.6.2 on the hard drive I have now and then clone it (via SuperDuper or something else) to an SSD later?

 

My stuff arrives today and I'm getting excited :D:)

 

Thanks,

 

Herb

 

Yes, you can clone your install to your SSD later. I've done this myself with my 10.6.2 install, when I went from a WD green drive to a new WD black drive. This would also be a great recovery exercise in case you have to restore from a backup in the future. Since my system is pretty much where I want it, I have Time Machine going, a saved image using Disk Utility, and then maybe a Carbon Copy Cloner image as well.

goldenaustin,

 

Thanks for the reply. Glad to know it works.

 

So I was putting everything together last night. Corsair did not include a 1156 mount with the H50 water cooler I bought. Looks like I'm running with the stock cooler until they get the mounts back in stock. Just a heads up to those of you thinking of buying the H50.

Just here, use the Installer:

 

Thanks, partner! I'm just using my backup to restore my OS partition because this installer f'ked up my system. Why didn't anybody just say that I only have to exchange the bootfile? (this time I'll wait for some early tests)
