Upgrading and Analyzing Apple's Nehalem Mac Pro

The two heatsinks on the Mac Pro aren’t interchangeable, so keep track of which one came from where and don’t try to force their installation if they don’t fit properly.
After we completed the swap, we powered the machine on and were met with the worst sound: fans that didn’t spin down. The Mac Pro refused to POST and forcing it to turn off revealed a CPU A Temperature Overheat warning LED on the motherboard.
Removing the CPU_A heatsink revealed the problem:
uh-oh
CPU_B was fine, but CPU_A was far from it. While there are no pins to bend/break on these LGA CPUs, if anything goes wrong the socket is toast. In this case, both the socket and CPU were beyond saving.
To date I’m not sure what went wrong, but I have two theories. Unlike desktop Nehalem motherboards, there is no clamp that holds the CPU in place. There’s a chance that during the heatsink installation that the CPU moved slightly and shorted as soon as it got power.
The other theory is that I somehow over tightened the heatsink on CPU_A. Remember, the chips I used had heat spreaders, the ones they were replacing did not. The added thickness of the heat spreader could have helped push the CPU too hard against the pins in the socket, causing some of them to move out of place.
Regardless of the how, what remained was that I now had a dead Xeon and a dead Mac Pro processor board on my hands. The CPU I could always replace from my stash, but I don’t keep many Nehalem Mac Pro processor boards in my parts closet. This would require a trip to the Apple store.
And if you’ve ever walked into an Apple store holding a Nehalem Mac Pro processor board, you’ll get some looks.
Thankfully, the folks at the Crabtree Valley Mall Apple Store in Raleigh, NC are AnandTech readers and quickly understood what had happened. They ordered the replacement part and I waited. If you’re curious, it’ll cost a bit under $400 to replace the processor board in an 8-core Mac Pro provided you allow Apple to keep your dead board.
The new board and its accessories
It’s been years since I’ve killed a processor and this would be my first LGA socket death, so I was admittedly nervous once I had the new board in hand. I went in and tried to replace the chips again, this time under tightening all of the hex screws on the heatsinks just to be safe.
I mounted and dismounted each heatsink three times before committing to the install. Nervously, I hit the power button.
I had good news and bad news.
The bad news, the fans were spinning at full speed. The good news? The upgrade worked. Initially I didn’t tighten the heatsinks enough so some of the memory channels weren’t working, but a couple more spins of the hex key and I was in business.
The fans spinning at full speed were caused by the thermal sensor on one of the heatsinks being dead. It looks like it died when the first CPU shorted out. The folks at the Apple store had to order me a replacement heatsink as well.
After the smoke cleared and my embarrassment subsided, I had an upgraded Nehalem Mac Pro.
I started with a pair of 2.26GHz Xeon E5520s and ended up with a pair of 2.93GHz Xeon X5570s.
Gaining access to the processors is far easier than the previous generation Mac Pro, but you have to exhibit more care in physically replacing them. The fact that the CPUs I used had integrated heat spreaders hasn’t caused any problems either. Temperatures are well within reasonable limits, the fans are just as quiet as before and Turbo mode still works.

Here's my take on this:http://www.tomshardware.co.uk/forum/page-262853_10...">http://www.tomshardware.co.uk/forum/page-262853_10...
Can't remember the exact price in USD, but it was around US$6000 too. And that's with a very-high-end cooling solution.

I'm not sure what the author or others here are talking about when they say Apple's extremely outrageous prices are due to Intel's price hike. There is no price hike. There was no price hike. Either the author is misinformed or it's a straw-man technique being employed in order to justify and excuse Apple having gone off the deep end with their price scheduling. With so many of the comparisons in this article omitting the 2008 Mac Pro models all together and only comparing the 2009 to the 2006, I'm to believe the later.Here are the prices of the respective chips at the time the respective Mac Pro machines were released:
2008 Models:
1 x 2.80GHz E5462 Harpertown: $797 ($2299 overall Mac Pro price)
2 x 2.80GHz E5462 Harpertown: $797 x 2 = $1594 ($2699 overall Mac Pro price)
2 x 3.00GHz X5472 Harptertown: $958 x 2 = $1914 ($3599 overall Mac Pro price)
2 x 3.20GHz X5482 Harpertown: $1279 x 2 = $2558 ($4399 overall Mac Pro price)
2009 Models:
1 x 2.66GHz W3520 Bloomfield: $284 ($2499 overall Mac Pro price)
1 x 2.93GHz W3540 Bloomfield: $562 ($2999 overall Mac Pro price)
2 x 2.26GHz E5520 Gainestown: $373 x 2 = $746 ($3299 overall Mac Pro price)
2 x 2.66GHz X5550 Gainestown: $958 x 2 = $1916 ($4699 overall Mac Pro price)
2 x 2.93GHz X5570 Gainestown: $1386 x 2 = $2772 ($5899 overall Mac Pro price)
As you can see, there is no significant price hike and in fact Intel has provided a massive price REDUCTION in offering the Bloomfield line. This delivers a second more severe slap in the face from Apple to it's user base.
Just look at this price scheduling:
2006
Mac Pro Quad 2.0GHz $2,199 NEW
Mac Pro Quad 2.66GHz $2,499 NEW
Mac Pro Quad 3.0GHz $3,299 NEW
2007
Mac Pro Quad 2.0GHz $2,199
Mac Pro Quad 2.66GHz $2,499
Mac Pro Quad 3.0GHz $3,299
Mac Pro 8-core 3.0GHz $3,997 NEW
2008
Mac Pro Quad 2.8GHz (2008) $2,299 NEW
Mac Pro 8-core 2.8GHz (2008) $2,799 NEW
Mac Pro 8-core 3.0GHz (2008) $3,599 NEW
Mac Pro 8-core 3.2GHz (2008) $4,399 NEW
2009
Mac Pro Quad 2.66GHz $2,499 NEW
Mac Pro Quad 2.93GHz $2,999 NEW
Mac Pro 8-core 2.26GHz $3,299 NEW
Mac Pro 8-core 2.66GHz $4,699 NEW
Mac Pro 8-core 2.93GHz $5,899 NEW
That's a $1,000 to $2,000 price hike on Apple's part and the first of it's kind in the past 10 as I've researched it. It might be due to poor sales or future economic projections, I have no idea. But it's unprecedented and completely unjustified by looking at part prices and other offerings in the industry.
I recently priced a DIY build and I could assemble a system with 18 DIMM slots, 6 PCIe slots, 36GB RAM, two quad-core 3.2GHz Nehalem, typical drives, cards, and case go for well under $5k. Apple wants $6K for much much less.
Something isn't right in Denmark!

Thank you for posting this. I'm a frequent reader of Macrumors.com forums, and I actually made a similar chart showing the very similar launch prices of Xeon 5400/5500 when new and how the massive $1000+ increase in price of the new Mac Pros are totally unjustified and ridiculous.
It would still be overpriced, but a far better deal if they tossed the 2.26Ghz in favor of the 2.53Ghz or 2.66Ghz as standard, with the 2.8Ghz and 2.93Ghz as the upgrades. (the 3.2Ghz is clearly too hot) This would be far more similar to the Mac Pro configurations in the past, where the base CPU + 2 upgrade levels usually represented the 3 fastest CPUs available (or nearly that).
To show the huge discrepancy, there are 6!! CPU levels above the 2.26Ghz 5520. (2.4, 2.53, 2.66, 2.8, 2.9, 3.2)
I was looking forward to maybe picking up a Mac Pro for the office, (software dev) but I'm not sure now. If the HAckintosh crew gets to a certain level of progress that offers no-hassle installation and complete compatibility with mainstream components, I can see many enthusiasts who want to dualboot OSX using high-clock speed Core i7 boxes, with loads of ram, SSDs, RAID'd drive storage, GTX285s, etc, and still spending far less than the single-cpu 2.93Ghz Mac Pro.

Firewire 800 works with 400 and 200. You just need a cable with the appropriate connectors, it will auto-negotiate the connection.Firewire rocks.

Too many sites get in mac vs pc battles any time a mac review goes up. I'm not going to bash apple and talk about how overpriced things are. But honestly, I've always been a pc person. In the past apple did have some innovations to tout and some people could justify the premium price. But looking at these 2009 models, it's a disgrace. for 3k+ we are getting 640gb HDDs, video cards with 512mb frame buffers, and 6gb of ram. And in return you get a xeon processor. For a company that tries to cut a niche out by offering the highest performance for a premium, this seems like a joke to me. Its like taking a chevy cobalt and putting a corvette engine in it, then trying to sell it for the price of a Ferrari. It seems to me when it comes to the desktop market these days, people are paying thousands of dollars because they like apples OS, and overlooking the hardware as long as the case looks cool and has a xeon sticker on it. Unfortunately most tech sites these days are in love with apple and just pretend that everything is fine and dandy. I am glad that you pointed out the deficiencies Anand, but I think all apple fans should be more vocal and actually show some disgust for your beloved company for once. If you are going to pay all that money, you should atleast get some innovation to show for it.TheFace - Tuesday, July 14, 2009 - link
Since when has apple been all about the performance of the hardware? Apple is about the performance of the hardware/software package. These aren't corvettes or ferraris for you to zip around fun-town with. These are peterbilts and mack trucks to get work done with. This is a PRO model. Just because it LOOKS like a regular pc with it's big boxy structure, doesn't mean it's your home PC. I will concede that the author of the article does make some valid points about the lack of SSD and video card options. The fact is though, the mac pro isn't for the l337 who build SLI OC'd gaming rigs.If you don't understand that Apple rarely makes an upgrade without having an unveiling party about it, then you just don't understand Apple. I'm not saying that that fact is a good thing, but they certainly generate more press and hype than other computer makers.

Interesting that you state, " I'm not going to bash apple and talk about how overpriced things are." then you go on to do virtually noting but this.Are Apple's Mac Pro systems over priced? Yes. Are they more over priced than historically for Apple? Yes. However, as Anand points out this seems to be a trend with all tier one vendors. The equivalent machines out of HP and Dell are similarly or higher priced. Is this justifiable? No. They are all just gouging their high end users.
mesiah - Wednesday, July 15, 2009 - link
No, I did not bash apples price. I did not compare it to comperable PCs. I clearly pointed out that there is no innovation here to demand the premium price. But people like you are so used to having to defend your purchase based on this argument, thats all you've got. This is not a mack truck by any means. Real workstations have more than 3gb of ram standard. Real workstations have more than a measly 640gb HDD. Real workstations come with high speed SSD or SAS system disks. Yes, it is capable of high end graphics work. And yes, you can get a dell for $8000. But you are making that comparison not me. If you want to make it, go see what you get for 4k from dell. And those dells are not marketed at the main stream. If I walk into a dell store a salesman isn't going to try and sell me a workstation because I am a power user. When I walk into an apple store there is no hesitation to push me in the direction of a 3k+ purchase. But none of that was my point and not what was discussed in my comment. It was simply, where is my innovation that apple is supposed to be all about? I'm not talking about some quad sli water cooled system, I'm talking about simple things like 6GB of ram standard. SSD system drives. Atleast a TB of storage. Seriously, this is for power users and it comes standard with 640GB? I will admit apple gets some things right. And they are damned good at marketing. But please people, you don't have to kiss steves ass all the way to the bank. Don't make excuses for products that are clearly lacking. Otherwise your precious macs will just continue the long slide into bland vanilla every day systems and you will still be paying premium prices for everyday merchandise.
