It could be that they just dont work in a Mac Pro. I have not verified but I think you should be able to run off a single CPU so you can try them individual to see if maybe one is bad.

I've made a connection which I've got access to Clovertown CPUs: 2.66GHz at 1333MHz bus for $420 each ($800/pair) if anyone is in need. I've been completely unsuccessful in getting 1066MHz bus CPUs (2.4 of 2.66) for overclocking though I still wish I could get my darn 2.66GHz running at 3.3GHz! Just need to freeze them! or perhaps run them at a higher voltage? Anyone know some serious MP LogicBoard mod to force higher voltage to the CPU? Maybe solder the A/C input right to the CPU? (j/k)

Just awesome! This logicboard is absolutely bizzarre! It's got green LEDs all over it, a piercing blue one flickers when you plug in the power, the memory risers have a pair of green LEDs, it's got 7 buttons on the logic board, (Including the "PWR and RESET" where you see a spot for them on the current logic boards, so you can power it up without the front board connected. I'll upload photos shortly!

Oh, and it can run a debug mode at startup, don't know if all mp's can, but rather than the apple you'll see just the console doing it's thing!

Only thing, it won't sleep. It goes to sleep quick like normal, but when you move the most it cold boots... strange!

Nice thing is, the power supply in the huge montrosity of a case was a normal MP PSU, just slid right in my MP case I bought! Came with all the wires I needed as well. One thing I found was the DVD drives get their power from the LogicBoard! So plugging your 8800GTX (those of you who have) into the molex conectors for the DVD drives might not be a great idea!

What you are seeing is the boot up verbose mode, any mac can do that. That is cool it came with a real Mac Pro PSU! So if you go into System Profiler what Model Name and Identifier is it coming up as?

There should be 2 6 pin molex connectors on the motherboard as well just for PCIe video cards.

red = prototype
blue = production

Guys,

I just found service manual for Octo Mac Pro (not the early 2008 one), if someone interested PM me and I will send it to you (I can put it on Rapidshare, but I don't know if we allowed to post that kind of thing on the board).

Work in Progress... Finally got my cooling system from Koolance; also using some stainless steel tubing fittings that I had lying around. Order received dual 120mm 700W heat dissipating radiator, two 120mm fans, two Xeon block coolers, four memory block coolers and a ton of G 1/4 - 13mm compression fittings. Can't wait to put this bitch together. In the meantime, I'm a few steps from completing custom Hard Drive / Opto Drive Carriers (Pain; however who wants to spend $250 on four HD and one Opto Carrier when you can make it yourself from a piece of sheet metal, sharpie, ruler, and cutting wheel). Will post my progress... peace and love.

Now that's a cool system (pun intended).

Do you have the logicboard and all the other goodies? My big question for you, how much power will the cooling system require? I ask because I just recently discovered that the molex connectors which power the optical drives, plugs into the logicboard, thus pulling huge amps from those ports for some of those crazy cooling systems (i.e. the peltier) isn't a good idea.

Are you planning on having you cooling fans speed controlled automatically or manually or at all? I've been saved by Nagal's transistor based thermistors (Could only fine them in bulk of 20, but hey, I might need extras).


Oh, and a general Shoutout: If anyone finds any information about that red prototype logicboard, I'd love to hear it, I'll even offer a small ransom if someone can get me the layout of all the jumpers on the board!


Have fun!

Hey... the fans consume 9.6W.. the pump consumes 18W. 27.6 Watts total. That port can power two opto drives which should be 1.5A per drive or 36 Watts total. I might just power the fans directly from fan ports on logic board and pump from opto drive bus. Nonetheless, in the clear whatever route I decide. Has anyone confirmed success with Harpertowns on ver. 2 logic board? I'm still trying to discern the difference between socket 771 and LGA 771; both are refered to as the same--- socket J. Haven't found anything useful to answer this... Could someone please shed some light on why these two references are used to describe socket J.

Thanks

My understanding is this:

Socket J is named after the codename "Jayhawk", and refers to Intel's socket naming. They tend to name things socket M, socket T, etc.

Socket J is implemented as a Land Grid Array (LGA) of 771 contacts, thus the LGA 771 naming of the number of contacts and the grid. The use of Socket 771 is used by some motherboard manufacturers, who don't wish to use the Intel nomenclature of Socket J or LGA 771, but they all refer to the same thing.

The is the same for other socket types such as Socket T, LGA 775, and Socket 775, which are all the same thing.

I don't know if I answered the question, but I think the answer is Socket J, LGA 771, and Socket 771 are all the same thing.

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 ?

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!

http://forum.insanelymac.com/index.php?sho...mp;#entry674455

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

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?

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...

Dang! I just got my weekly Buy.com e-mail, WD 1TB Hard Drive $189 free shipping!
http://www.buy.com/retail/product.asp?sku=...amp;dcaid=17654

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!

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.

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..

It's Full EFI Pure Mac Pro, so it takes the retail perfectly, Leopard or Tiger...

Nagal... could you please confirm the "macpro2,1" chipset when you get a chance. Thanks brother.

I have just started to build a MacPro with no knowledge of building computers. This will be a great learning experience for me and will post pictures of my build regulary. My prototype Mac Pro logic board should be coming tomorrow along with 2 riser cards.

Coolio... just to let you know... the Harpertowns do not work with the proto board according to Listed1's account.

That isnt much of a problem. Could i use 2 Intel quad cpus?

Hally you have to be careful what you put into this machine. If you have no knowledge of building computers I strongly suggest you do a lot of research and posting around before agreeing to this build!

These processors should be compatible if you want to build a Quad Core: http://www.pcbuyit.co.uk/dept.asp?dept%5Fi...FSB+%26+1333FSB

Look at the Xeon 5150 2.66GHz Chips. I think that is what Nagal recommended me!

KIMOSABE Thanks a lot for your help, yeh i appreciate it. I will look into those processors you just listed. As promised i have uploaded the mac pro components i have so far. I Bought the Mac Pro Case for £65 as the legs are damaged, but nothing lego bricks cant handle. The Logic board and 2 riser cards were £150 from the states off ebay however i had to pay £40 Customs fee. Tomorrrow i am going to pursahe M3.5 8mm screws to mount the motherboard and also I am ordering the 4 hard drive carriers and front panel card tomorrow all for £35 inc postage. So far i have spent £255!Also KIMOSABE will the Xeon 5150 2.66GHz Chips work on the Mac Pro prototype board?Regards Hally

Those CPUs most certainly will! Any 51xx and 53xx series CPU will work in this board. I have not tested, and I would venture to guess the 54xx will NOT work, and I've also found out the 50xx will not work either (Not that you'd ever want to use those!)

Your most cost effective price/performance CPUs really will be the 2.66GHz quad core CPUs all over ebay right now. The main seller selling them is the fella myself, and other here, got the 2.4GHz (which we overclocked to 3.0GHz) CPUs, good honest seller.

I've got a pair of 3.0GHz Dual core CPUs I'm going to be selling, but those little buggers fetch about $1,100 per pair, whereas you can get a pair of 2.66GHz Quad Core for $499. Go figure. I recommend omnitechnologies.biz for the RAM, as 2GB sticks are about $74 each, and they don't charge excessive shipping (Just make sure you get a total of 4 sticks, as that best utilizes the memory lanes). Where'd ya find the MP case?

You're definitely on your way to getting a killer MP for minimal cost!

Did you prototype come with a power supply like mine did? That's a $300 value right there!
Also: What type of video card will you be using? If you're going low end, rather than buy the 7300GT, grab the new ATI's as they will work in this board, and for $149 at apple.com it's not bad!

And lastly, what are your plans for cooling? Are you going to order apple parts, or do some different fanning? Are you going to order apple heatsinks, or go with the ones Nagal and I used? (Far superrior cooling with those, better price, and all you have to do is make a little thermistor out of those transistors!) I've got plenty of those transistors laying around if you want to just pay post, I'll shoot them on over to you if that's the route you go!


WELCOME! To the Building a MacPro Community!

Oh! And DO NOT push any of the buttons on the logic board! I'm not 100% Sure, but I believe on my 1st board, by pressing one of the buttons on there I reset the firmware back to developer revision, as after I pushed the buttons it started booting in console and no longer going to sleep, where as board #2 has release date firmware and will sleep like a puppy. Just my 2 cents!

Thanks Listed1st.com for your rapid response! I found the Mac Pro case on ebay.co.uk and immediately bought it as i know how rare these cases are to find. However it was completely gutted apart from the PSU fan and optical drive carrier. So my £65 i spent on it is likely going to rise to over £100 once i go and buy the4 hard drive bays, front board, cabling etc.

When i ordered the prototype mac pro baord and 2 riser cards i didnt want the case as it looked really ugly and heavy, and i wasnt sure if the PSU would fit in the Mac Pro case so i took the safe option and only went for the 2 riser cards and logic board. I found a Mac Pro PSU for £100 on ebay.co.uk which i am most likely going to buy. As for the heatsinks, i have no expertice or knowledge of transistors so fitting the heatsinks so and Nagel have is likely to be too hard a job for me. I will search around ebay for some apple heatsinks mosty liekly. i am thinking about the Xeon 5150 2.66GHz Chips as this would make the Mac Pro a Hapertown am i correct? As a resistant living in the Uk i tend to use ebay more than online sites as most of them are based in the US and postage charges are terrible.

Reagrds Hally

Hey Hally I am pretty sure you came across the same eBay shop I did for the parts. I'll link you to it just incase I'm wrong as it seems a good shop with MacPro Cases/Power Supplies!

http://stores.ebay.co.uk/wefixmac

They seem to be out of MacPro components right now but keep checking there.

http://stores.ebay.co.uk/ScrumpyMacs-Used-G5-MacPro-Powermac This one is also another great eBay shop for MacPro parts

No, I don't think so.

Xeon 51xx - Woodcrest
Xeon 53xx - Clovertown
Xeon 54xx - Harpertown

Hi KIMOSABE, may i ask where you got the screws from to fit the logic board to the case as i am finding it hard to locate some?

Ok thanks Bearcat i understand now.

Regards Hally

LISTED1ST.COM forgot to mention about my cooling method. I am just going to buy the front fans and rear memory fan to cool the mac pro unless i buy bigger heatsinks in which i will proberly resort to liquid cooling.

I have pressed 1 of those buttons on the logic board but it does not have a PSU connected to it so wouldnt have an affect would it?

Can anyone tell me where they bought the screws to fit the logic board to the case (M3.5 8mm screws) in the UK

Regards Hally

Also, the 5150 is a dual core processor, so you'd end up with a quad core Mac Pro...

so how much does one of these bad boys cost? it sounds like it would be around 2 grand usd is that true?

No they cost about $300 each!

Hey Hally, I couldn't tell you about where you could get screws from as I've not yet built a MacPro. It's an upcoming project. I am currently planning a Hackintosh with around 3 Operating Systems on it and hopefully if I get a grant from my college I'll use that money to buy parts for a Mac Pro =]

Your best bet is to message Nagal but your local PC store or hardware store should stock these type of screws!

Ok thanks anyway KIMOSABE. I shall be visiting my local hardware shop soon!

Can you tell me what the difference is between this CPU INTEL XEON 5150 2.66GHz 4M/1333FSB SL9RU and this one INTEL XEON 5150 2.66GHz 4M/1333FSB SLABM,

The only difference i could notice was the serial number.

sorry i meant an entire build

My build is going to cost around $1000 to $1500 depending on what CPUS and graphic cards i get.

Nagal did you fit the internal speaker for the mac pro, if so how much did you pay for it and where did you get it from?
