Building a MacPro, Yes, a MacPro not a Hackintosh Options

I must agree with Bearcat, from what I researched they are all the same thing. One thing to note however, is the new CPUs the Mac Mini uses, though they are the same pin and socket, there is some sort of different configuration, thus the new 800MHz bus chips won't work in the Mac Minis (Aside from the bus speed being different, the pin configuration, though the same format, the pinout is different).

The Socket M (I think 471) is what's used. Chips such as the T7200 vs T7500

Thanks for the insight... if possible see if you guys can dig up some tech note that can resolve this enigma... don't get me wrong I believe that you are correct BearCat. Thanks again.

So a little wiki action tells us "Socket J (also known as Socket 771 or LGA 771)" http://en.wikipedia.org/wiki/Socket_J


Also, I read about a new 45nm Chip in the Xeon form, the x5200 series! Curious to know if they'd work in the Mac pro, the ideal chips looks to be the X5260, But at $995 each 3.3GHz dual core chip, I'm thinking I'll pass on it. (Found one on ebay)...

And so sad that I wasn't able to get the Dempsey core working, I would have had so much fun with a 4.3Hz Quad Core Mac Pro! Granted it'd probably run about that same speed as a 3.0GHz Woodcrest core, but still...

Here is the service manual for 8 core mac pro (not early 2008)

http://rapidshare.com/files/99020958/macpro_8x.pdf.html

Connectors for logic board are on page 91.


Also, does any of you know where I can get the logic board for early 08 mac pro's ? Looked and called pretty much everywhere and everybody and none of them have it yet.
Any help or hint on this will be greatly appreciated

Thanks

EDIT: Forgot to mention that there is a small difference between mac pro and 8core mac pro in enclosures and logic board.

Hey guys... a quick heads up on Mac Pro fasteners (screws)... http://www.microfasteners.com/ Just got my order for the odd sized metric screws for the logic board's standoffs; (M3.5). 50 pieces dirt cheap. You can purchase all fastner needs for around $20 bucks; that's how much it cost me for ever screw they that was needed. Use www.applepalace.com parts list to organize your fastener list, they list them with size description.

I found thoses pictures I took of the 3.3GHz 8-core, all I got was 5 minutes of use before the heatsink thawed out. The photo of the heatsink was when it was all frosty, and hitting 90 Gigaflops was pretty cool! But it's just not cost effective to use 1 can of air duster per 5 minutes of use, gets expensive! You can see the tape I put on the heatsink, this allowed me to fill it up with the freezing liquid which just boiled off within minutes.

Does anyone know what maximum power can the optical power harness handle? Two drives @ 1.5 A each = 36 Watts. I need to squeeze 45.6 watts = 3.8 A. 20 gauge cable is rated for 3.3 A = 39.6 watts. Thank you....

So I finally got the front fan assembly and wired up the thermal sensors (Thanks Nagal) so I've included a snapshot of system profiler....

Turns out I've got model identifier M43ADP1,1 Fun stuff!

I also, for kicks and giggles, put in a production memory riser and it worked just fine. Strangly enough, there are 2 jumpers down by the CPUs and if I change them my system decides that it only has 1 processor with 7 cores! (Yet activity monitor shows 8 cores, and the performance doesn't change).

Also, there are 3 jumpers between the PCIe slots, I'm guessing they'll manually control which slot get's how many lanes. another nice feature is 2 additional 4-pin fan plugs on the board

Anyone have any requests as to haev my try anything with this board? I'm feeling a little more daring with it than I am with production boards that cost a fortune.... (And no requests to use it as target practice).

Oh, and a general shoutout: It will NOT sleep! I put it to sleep, the power light dims like normal, I press the"anykey" and it wakes up to a cold boot. any ideas on how I might fix this? Also, it always boots in console, how might I go about changing that? Thanks crew!

Glad those thermal sensors worked for you. How is your fan speeds? I still have one fan (the top fan of the two front fans) that always wants to run full speed.

As for your sleep. I lost sleep function when I upgrade to 10.5.2 so it might not be your board if you are running 10.5.2. just a thought.

No idea about fixing the booting in console. Normally, you can set a Kernel Flag (-v) in com.apple.Boot.plist but I doubt that will help you as it is something you manually need to set. I wonder if one of your many jumpers sets that?

Anyone seen any info on a successful Harpertown boot on Macpro2,1 ?

[Listed1st.com]

Both fans run at 500RPM (Though I keep them at 900 for good measure, and because my chipset heatsink is about 1/2 the size of the production boards). I'm assuming you did a SMC reset for the fan issue? I ended up buying a front fan assembly and just hitting it with the dremel so it fits fine with those huge heatsinks, they do an amazing job! I'm running a fresh install of 10.5, also, strange thing. The boot issue didn't seem to start until I hit all of the buttons on the board (SMC reset and all).

Does your system have the same issue when sleeping of just cold booting? I wonder if it's somewhere in the EFI that's not telling it to pull the data from memory...

I still have not heard anything about the Harpertown on the 2,1.

I cannot remember if I tried a SMC reset yet. I will give that a go tonight. My issue with sleep was that it just would not wakeup at all, I would have to power cycle it to get it back up and running.

Okay, Awesome! Red Logic Board #2 arrived today, I was led to believe it was a non functioning unit. But I couldn't just let it sit untested, so I fired it up... Boom! It works flawlessly! It even has the production firmware! System Profiler shows it as a Mac Pro 1,1! Crazy! It sleeps just like it should and everything! So looks like I'm going to need to rip out the other board I have, or someone reading this thread is going to tell me how to copy the firmware and flash it onto my other red board, and all us folks who have these prototype firmwares will be freed!

Anywho, added a few higher res pictures just for kicks,

Oh, and on the "Who's lapped their CPU?" thread I took some before and after pictures of a core solo CPU I "lapped" with a cute story about how I lapped the CPU in my Macbook Pro... haha! I think it's kinda funny!

looking good so far after you get all that make it look factory even more by buying all the iternal casing and all that

[gramarye]

Listed1st.com, nice pics! and oooh shiny red protoype mac pro logic board. sorry if i missed it, which CPU Heatsinks are those you're using in the photos?

[Harloe]

I wish I had the money to build a Mac Pro =[ Maybe I'll use my student grant come september to build it =D

The red logic board looks really cool but I prefer the blue one =] Damn I wish I had the cash xD I'll have to sell some possessions...

Okay, so just for fun I decided to check out the chips under those heatsinks on the Logic Board.
The main Chipset under the centermost heatsink:
QG82016MCH
QL94ES
L605A289

The smaller chip under the larger, but shorter heatsink:
QG80003ES2
QJ90ES

Unfortunately I don't know what they translate to! So anyone with better searching skills, have at it!

[Harloe]

Listed,

are you using a retail version of OS X? Or is this like an OSx86 Hack? I imagine you'd be able to get a retail version of it on seeing as it is apple hardware; even if it is prototype models.

[digitalperformer]

Could someone with a "macpro2,1" with Windows please use CPU-Z to probe Chipset for it's name.... someone on apple's discussion forum stated it was greencreek 5000X. Sounded iffy about it. If someone can confirm the chipset, and if it is compatible for Harpertown according to Intel's white papers, I'll buy the Harpertowns and be the test dummy. Let's make this sh*t happen on a global scale... BIZNATCHEZ!!!! HELL YEAH!!!!

Hey Bro... I searched engined those nomenclatures with little success... it reads as "ES" Engineering Sample... I'm guesstimating..
