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

[exseven]

@tonymacx86

hi, i want to try osx on my pc, so I choosed to follow your guide you posted here: http://tonymacx86.blogspot.com/2009/12/ins...ectly-from.html

 

But im not sure where to get the retail DVD. Can I use the Upgrade-DVD they sell for 30$ as well?

Or do it have to be some different version?

 

I ordered some hardware and will try the install with it:

 

Gigabyte GA-P55M-UD2

Intel Core i5-750

G.Skill 2x2GB Kit

ATi Radeon HD 4550

 

thx for your help

 

 

 

i have had issues getting my 4550 to work with the p55 chipset (either get p55 fix (chameleon) or QE/CI (netkas) beta boot) not both). Might want to find a different vid card or wait to see what PC EFI 10.6 has when/if it comes out

Hey rekursor-

 

Good work on the RC4 mods- it's cool to inject your UUID directly into com.apple.boot.plist! For anyone who's a bit lost, all you have to do is follow these steps:

 

1. Find your UUID for the boot drive by entering Disk Utility and right click on your Snow Leopard install drive in the left column. Choose Get Information and look for Universal Unique Identifier.

 

2. Open and edit your com.apple.boot.plist (located in /Extra) in textedit, or property list editor as shown in the pix below.

 

3. Remove PlatformUUID.kext if necessary and rebuild caches.

 

4. Reboot and enjoy a cleaner system that has no UUID errors in Time Machine, iTunes startup, Superduper!, etc...

Thank you to all.

 

I visit many sites and lurk around, never posting, gleaning what I need. I have never undertaken such an involved and expensive gamble on both my limited knowledge and the "say so" of online strangers.

 

In the span of two short days I have built a fully functional (fingers crossed) machine that totally rocks.

 

I came to this fairly late in the game. I don't know the pioneer hackers to whom I owe gratitude, though, I thank you nonetheless.

 

I do know that tonymacx86 is the direct reason my computer is up and running. Thank you for your time, effort and patience. You helped save me a lot money and gave me a little bit a pride of accomplishment.

Has anyone gotten P55-UD3R to work well with sleep on 10.6.2?

 

I can get mine to go to sleep, but seems like I take a performance hit if I do so. Anybody have a good solution?

 

Hey, I'm on UD3R with i7 and I have sleep that works, with a pretty nice 9600 on GK.

I have taken my DSDT from this forum. I think it was Rekursor's which is on TonyMac's blog.

Good luck.

[LucaM]

That is absolutely right. BEFORE using any DSDT (besides the CMOS reset fix needed in SL) let alone compile a new one, it is best to have as close to a stable system (solid boot) as possible.

 

I agree, however, in my case my machine would not boot without a DSDT file in /. I got started with tonymac's DSDT compiled for his mobo and later extracted my own DSDT in Windows 7.

 

With tonymac's DSDT file, the P55 SATA ports were inactive and if I connected the HDD to any of these ports I would get the waitig for root device message.

 

After compiling my machine specific DSDT the P55 SATA ports were recognized and life was good.

 

So in short:

 

1) If you either do not have a DSDT file or have one that is not system specific plug your HDD to the Gigabyte chip SATA ports or the eSATA ports with an adapter cable.

 

2) If that solves the booting issues the next step is to extract a DSDT file and customize it. A good starting point could also be one of the system specific DSDT files in tonymac's library.

[Ooh_Gravy]

Can anyone explain how I'm supposed to debug these kernel panics? I'm trying to follow Tony's boot CD guide don't know how to work out where I'm going wrong. Is there anything in the panic log that I can use to identify the problem?

Hm, I followed the instructions but I'm not getting the UUID I placed in boot.plist. I'm using recursor latest boot file (v2) and I have a fixed UUID but not the one in plist. No platformUUID.kext in extra. Any ideas ?

[rekursor]

@wlp5

Like I said this normal that you can't read the same UUID because on recent systems, the way to go is to change the system-id, then the system calculates a *new* IOPlatformUUID from the system-id which is not visble other than in your com.Boot.plist file, still this one is not generated from a random uuid but from the fixd one that you put in your plist file.

So it does not matter because with this (now fixed) UUID, you should get the same platformuuid forever, whatever it is.

allright, which SATA ports are the Gigabyte ones? I have 6 Blue and 2 White, however because i'm on a p55-a board, i thought those were controlled by the Marvell controller

 

so I haven't solved the booting issue. I also am getting a "exception of class NilObjectException" error, so I can't even extract my DSDT

 

could someone explain what Tony's CD is doing that allows leopard to recognize my SATA that my install isn't? maybe i could just put a different system specific (like the p55-a ud3) DSDT to fix it?

[Eyecube]

Quick question!

I've just installed Parallels 5 and i'm just wondering is it possible to make it boot my Windows 7 partition? (On the same HDD). The classic boot camp selection doesn't work. Is there anyone who already did it? Or who knows how to trick it?

 

I did the UUID in the boot.plist file and removed the Kext. What does it change exactly? Just the name of the computer in About This Mac? (so i guess tricking the computer it's a iMac 11.1 forever?)

 

Thank you in advance.

[Treky]

allright, which SATA ports are the Gigabyte ones? I have 6 Blue and 2 White, however because i'm on a p55-a board

 

I would think still the white one are non Intel, the blue ones are with very high chance P55 SATA ports. Four high speed SATA ports not six. So the two on backpanel and the two on motherboard must be the non Intel SATA ports

 

i thought those were controlled by the Marvell controller

OMG,

I hope for you someone program a kext in some month for that.

 

so I haven't solved the booting issue. I also am getting a "exception of class NilObjectException" error, so I can't even extract my DSDT

Even in single user boot ? Would be enough to get DSDT.

If it had something to do with SATA, the only thing I can say: USB, if your board have Intel USB ports ?

Yes, but maybe impossible if you don't have an SATA to USB adapter.

I had no problems with SATA, I don't know why other people have.

Great ! Thanks for the help and thanks again to tonymacx86 for giving out instructions for us! Your help is once again greatly appreciated !!!

With Chameleon 4 ? I don't think the type of Mac depend on the UUID. It is still Mac Pro with and without UUID, in my case. Timemachine and iTunes identify the system on UUID as far I read.

I also have a UD3R, but with an i5, and sleep working perfectly. I did have some issues with KP's on wakeup, but they mysteriously went away after some change I made. I wished I remembered what it was. The welcome surprise is that SpeedStep is also working even though I'm overclocked to 3.4GHz, giving me a GB score in the 9000's. I'll rerun the test tonight to give the exact number. However, if I go any higher than 3.4, then performance and GB tanks to half. I believe it's related to the BLCK value, and again I'll post that value later this evening when I get home. I'm quite happy at 3.4, even though my system can do a stable 4.2GHz (with the old DSDT and no speedstep, sleep etc.). I'd rather do 3.4 with all the nice CPU features enabled.

Chameleon RC4 ? This helped in my case, but still not fix it 100%.

LOL

I have even thermal problems at stock speed and Turboboost enabled in my tight case .

And I would not overclock my CPUs anymore, since I have known what happens in the chip when it run far above the absolute maximum ratings. The material goes on wanderings when the current is too high. And the current it will be high enough, if chip run far out of specs. The maximum turboboost clock gives you the frequency the chip is rated at maximum. In this case the TDP will exceed the maximum value if all cores run at this frequency, but it will be not the problem as long as you can hold the core temperature low enough. If you go above this frequency the current through every core increase over the rated maximum. If you even increase the voltage you will have a much stronger current increase through every core. Such a CPU can run only a month, if you are really out of luck.

Nope not RC4, still with the RC3 with the patched boot file. What issues are you running into with sleep? I assume it's also UD3R board?

 

Are you saying "thermal problems" as in running too hot? I think I went overboard with my cooling options, ie. Full tower HAF 932, Corsair H50 closed loop water cooler, 5+ case fans, etc. At 4.2, I would never see core temps go higher than 50 degrees while using Handbrake and iMovie encodings. Under Windows, using the stress test load tools like Lynx and Prime95 it never went past the 70's and those are much much more intensive than normal everyday usage like movie encodings and games. At 4.2 I was seeing GB scores of about 10600 (with old DSDT), but since then, I compromised, and dropped down to 3.4 (with new DSDT), but luckily my GB score is still 9000's. Now at 3.4, I never see temps go higher than 40's, maybe touch 50's. Wonder if I just got lucky with my batch.

[wlp5]

I successfully enabled speedstep using the instructions at tonymacx86's blog. iStat reports 7-8 degrees lower at idle so that's enough proof for me.

 

I had to turn on all advanced cpu settings in the bios, leaving them at auto didn't do it.

 

I'm now wondering about turbo-boost. I currently have it disabled but turning it on gives me around 300 points at geekbench. Are there any issues with leaving it on???

[arynjon]

I have an annoying problem with my MSI P55-GD65. Firewire drives and video will not mount/are not usable unless I boot with the device powered on. If I turn the device off or unplug it, it won't work again unless I reboot. Does anyone have an idea how I could fix this issue. BTW, this is with the onboard firewire. I'm sure I could use an ad-on card and get it to work no problem (that's what I did on my other hack). I was just hoping to get by without doing that since this board has the built-in firewire.

 

Thanks.

[Bansaku]

Has anyone gotten P55-UD3R to work well with sleep on 10.6.2?

 

I can get mine to go to sleep, but seems like I take a performance hit if I do so. Anybody have a good solution?

 

 

In regards to my own sleep issues (KP after wake) they seem to be as rare as they are random. I have had my system on since Friday sleeping during night/work, and numerous times throughout the evening, and everything seems to be very stable in 64-bit mode. As for performance hits, I see none; just today Geekbench64 scored 9880 (ran immediately after I woke the system). Without any sleep fixes (USB/SATA and HPET fixes in DSDT) the score remains the same (aprx.). I see no increase in CPU temp, and speedstep/turbo works flawlessly.

 

 

I am however a little curious as to why so many of you are getting {censored} scores when overclocking. If I overclock to 3.5GHz on stock voltage (taking out HPET fix from DSDT, turning Turbo off in BIOS, and using NullCPUPM) my Geekbench64 score is aprx. 13 000. I see little difference in temperature whether I am in W7 or 10.6.2 when overclocked; Idle SL is 2'c cooler, but at full load spikes into the high 70's in both. I do see better Geekbench scores in SL over W7 (by like 2000pts.). Messing with the voltage I can run SL at a stable 3.8GHz, but the extra 300pts. and spikes into the low 80's at full load isn't worth it. Neither is the extra 5fps in Crysis...

Would you mind trying to recall what you did? I think I have a pretty similar setup with the i5 at 3.2 and really stable right now. Geekbench at 8500s, but if I try to enable sleep it drops way down.

[airecken]

So when I removed nullcpu and ioachi my geekbench score drops to 4000s, and i can never wake the machine up from sleep. just gets a black screen. i'm using the dsdt from tonymac's website for the ud3r and have verified that it has all the fixes needed for sleep. I would really appreciate seeing how others were able to get this done, especially if they have a 4890.

 

Thanks!

I honestly think Bansaku was right about the 64 bit part. I think I was testing Speedstep while in 32 bit mode in order to run the speedstep test utility and was getting KPs while testing sleep in that mode. Only until I went to 64 bit, did the KP's go away. Bansaku, does that sound consistent with your sleep KP issues?

 

You're saying that when you enable sleep, your GB score goes down? I don't think I ever saw an issue like that. It was either sleep with KP on wake, or low GB score because I overclocked too high. Bansaku was able to get to 3.8, so he's doing something I'm not doing as far as overclockability. Regardless, I'm happy though at 3.5. (I mentioned 3.4 in an earlier post, but it's actually 3.5). 64bit GB was 9157 just run right now. Idle is 27 degrees.

Try stock speed instead of 3.2. If this helps, then slowly increase it. Did you click all the boxes in Energy Saver under Preferences?

[airecken]

Yeah clicked all boxes under energy saver.

 

Basically, I'm running at 3.4 ghz core i5, temp 40s at rest (with the noctura fan which I thought was suppose to be good).

 

Anyway, I'm running 10.6.2 in 64 bit, and use the GB 64 bit. When I delete those two kexts, GB drops about 50%, and I can put the machine to sleep but when it wakes it gives me a black screen.

 

Did you set anything in your bios regarding sleep? Any way I can ask you to export your bios settings? Are you on firmware F4?

Sorry to ask but are you positive you have the right DSDT? At 3.4 with a Noctua, and speedstep working properly, 40s for idle is quite high. Before my H50, I had a Coolermaster 212+, decent, but not near a Noctua based hs, and I was seeing 30's at 4.2GHz. If speedstep is working properly, then you should at least be getting low 30's at 3.4.

 

BTW, how do I export my bios settings? I think I'm using F3 version, which is the first one that had the iPhone sync fix.
