Apple's Mac Pro - Upgrading CPUs, Memory & Running XP

Although the socket looks very similar to a desktop LGA-775 socket, it does have fewer pins and a different pinout so don't try to install a LGA-775 processor in these LGA-771 sockets. Thankfully only Xeon processors are LGA-771 so as long as you order the right CPU you should be good to go. We chose to go with the fastest CPU currently available, the Xeon 5160 that runs at 3.0GHz; the 5160 is also available as an $800 upgrade through Apple when you're ordering a Mac Pro.
Be extremely careful in removing/re-seating the Xeon processors in these sockets since all of the pins are in the socket itself and are a pain/virtually impossible to fix if they get bent. It's usually very easy to spot a bent pin just in case you do do something on accident.
Pay attention to the orientation of the CPUs that are in the Mac Pro when you remove them, and install the new ones in the same direction. You can also look at the contact points on the back of the CPU to confirm the installation orientation. As a final fool proof check there are also cutouts on the sides of the chip that will only let it sit flat in one direction. If you've never installed a chip into a LGA socket before, double and triple check you've got the orientation right before you pull that lever down. Of course you'll want to put some thermal grease on the new CPUs; be sure to keep the grease off of the pins in the socket and avoid using too much/too little.
With the new CPUs installed we mounted the heatsinks (don't forget to reconnect their cables) and installed the fan assembly. As a quick test to make sure that everything worked ok we didn't re-assemble the memory cage and did a quick boot into OS X to see if the new CPUs worked. Once we confirmed that they did, we completed the reassembly.
The Xeon 5160s were recognized properly by OS X and worked without a hitch, so it looks like there's a real, widely available upgrade path to Mac Pro owners down the line. As Intel processors are easy to come by, you shouldn't have any problems putting faster Xeons in your system.

Hey guys I`ve reading your comments mac vs windows and I will say that I have worked extremely in a pc for years and this what I have to sayIm a Music producer and I use alot of heavy softwares to make music today softwares require alot of resources from the computer, I was working in pc for years because as all we know mac is so expensive and I couldn`t afford it many years ago, then after working alot in pc i decide to save money and start using a mac and these are the reason :
first microsoft dont care about the softwares they sell there is always a bug tu fix and when you download the right patch something else is screw it up then at some point you get tired to install buggy files to the computer and is so common than suddenly you have unexpected errors with the os even in xp that is the best windows system now for pc.
I guess we dont need to talk about the horrible windos vista that is a kind of mac system copy as always seems that gates likes to copy only what jobs do.but in wrong way just take a look of the designers of the os i wont go to deep in that
and add to that spam alot of them every where in internet plus hundreds of virus that people that doesnt have anything better to do program so add to your
so called cheaper system license for all that shit to keep your pc secure if that`s possible at some degree
so you can build the most powerful pc in the world but is not about to have american muscle in there is to have something that works smootly and will work everytime you need it and that`s what mac does believeme i have been working with mac i have used very heavy softwares and used the ram at maximun my hard disk is completely full and my mac work just as the first day i opened the box something i can`t say about my old pc that at the end i needed like one hour to shutdown the system due to that the system was like shit because of the extensive use
when you need the computer to make your living you need something in that you can trust also I play live with programs like ableton live and i would never trust a pc for that what happen if the system starts to crash in the middle of the concert?? and that happen alot with windows also with all those virus, i had the bad experience that a fucking one screw my hard drives with alot of music in there my own compositions so i started to hate windows for many reasons and that`s just the first layer
if we talk about how smart are alot of applications like expose to give you a short and easy example, all that stuff really works when you are using the mac alot, maybe if you just use the computer to check email, watch porn in internet and play video games a pc will work for you also to be a pseudo expert builder and argue with friends that you build the best machine in town with lights inside etc etc but for serious work i would recomend a mac you have tons of smart applications watch how easy is to get your back up with time capsule for example as a professional i need something that helps me to focus in my work and not to fix errors in the system that i guess that`s why microsoft is selling you the software he is not giving it as a gift , why should i work for them to fix my system??
also microsoft just want to be competitive in price and not in quality check all the market where microsoft is involved, video games same story xbox 360 cheaper but the system is just crap and buggy and some that where really good systems like playstation have to go cheaper in components because they build good systems meant to last alot so now is not the same because microsoft is half price than ps3 now ps3 is alittle cheaper than before but you get less stuff in it and in the long therm you are paying more for something that doesnt work as suppous to, this is the same with pc`s , video game consoles palm os same shit all around with them but most of the users are only concern of who has the bigger engine in town and the cheaper one and not how to use it properly and the one that really works because at the end is useless the most powerful pc runing ever if crashes twice at day and you spend many hours fixing and going to forums to check what is that error that the computer is showing you.

I have really nothing to say on the subject of Mac vs. Pc. But please for the love of all that is good on planet Earth, I ask you when you are trying to make a valid point do not spell and punctuate like a teenager. Hell I am teenager and I have better punctuation then you how sad is that.checkwebsitetraffic - Thursday, February 6, 2020 - link

Anyone tried upgrading one of the early Mac Pro's with one of the 1333GHz FSB socket 771 Harpertowns? If not, does anyone know of a reason why it wouldn't work?Thanks

upgrade the Mac pro to the quad core 3.0 LGA 771 133mhz cpu's @ 80w? Has it been tried yetSpetznatz - Thursday, January 10, 2008 - link
Anand -- any idea if the same can be done with the new Penryn processors -- simply drop them into the first-gen Mac Pro motherboard?The 5420 (2.5GHz, 1333MHz FSB) at about $600 looks like a good price/performance swap for my current dual-core 2.0GHz Xeons).

Maybe I missed something obvious, but I can't seem to find how to put the system in quad channel mode?My Mac Pro is still running with the default 2x512MB and I'm about to upgrade to 8GB. I wanna know if I should go with 4 x 2GB or 8 x 1GB?
I prefer the former but if performance is gained I'll go for the latter.
I did read that banks should be filled 2 on board A and 2 on board B and I think it's logic to conclude that spreading 2 pears over the two boards creates quad channel. I still like to see that confirmed though ...
Could someone clear this up for me please?
Thx.

The first page goes on a few paragraphs about how rank within an FB-DIMM affects speed, but I didn't see any sure-fire way of how to determine the rank of the module before buying. I did find a document that suggests that 1GB and 2GB modules have a rank of 2, and smaller modules have a rank of 1. I can't find that page right now.I am still a bit confused as to how that makes a difference, is it as if there were two memory channels within the memory module? That would be a pretty interesting idea. It would be nice if this was benchmarked. If that's true, then the FB-DIMM concept doesn't seem so bad after all, the only problem is how much heat the AMB produces, the cost of the units and of course the latencies.

In the end, I think Apple finally hit a home run, and some PC diehards who even if the Risen Lord came down and asked them to praise a Mac, would balk at the idea will never accept it.It always goes back to the silly gaming argument which is all but pointless when your talking about workstations. I mean can you play Quake IV on your Octane or Sun UltraSparc III workstation? Who cares about games? It's not like the game software is written for OS X anyway, it's for windows.. and DirectX that is where the optimizations are, not OpenGL.
if you want to spend hours and hours tinkering with your build-a-pc box, knock yourself out. I just want a machine that works, and works well!
Peace Out..
