    Can't help with Raid ~ the hatter may be able to help.  Use SSD hard drive so don't worry about it.   Not into music or photos so do not need so much drive space.


    The hardest part of changing the processors is removing the Torx screws which are beneath those huge heatsinks, and if possible get that 8-10" driver first.  See my earlier post on changing over.  After install suggest downloading and using smcFanControl with which you can increase speed of CPU, PCI-E and hard drive and rear fans.


    With the X5355 all ranges of temperatures seem well within normal ~ CPU 26ºC, HDD 17ºC,  PCI-E expansion slots 27º.  Good luck and keep us posted mikecorp!

    Successful Upgrade


    2x2ghz Geek bench before upgrade 4716 

    after upgrade

    2x 2.66ghz E5355 Quad core Geek bench has 10194



    Process is quite easy if you know what to do. I did a research and watched this video on the youtube: http://youtu.be/HBivTJ0sitM   This guy was slow and easy, after watching it, I did not need to go back to any tutorial.


    Hardest for me, was to find a long 3mm Torx. I worked with only 15cm, that is the minimum of all. I bought a last one in Hornbach (German hardware store). I had to saw off the handle to get to front heatsink screws.


    Next upgrade will be ram.

    from 8 to 24 if I find somebody who will ship it from US.


    Thank you all for help!

    OWC ships but can't tell anymore where, what hardware etc like the old AD forums. Crucial UK and Kingston (Europe) are quality and probably going to be easier and competitive. So for you, I'd say Kingston.


    Compiled some links for parts for EU region.

    ALTERNATE Europe


    Kingston Mac Pro RAM


    OWC SSD Europe


    And that assumes you need 24GB. The ideal is still going to be 4 x 4GB, to use 4 DIMMs (two per Riser), or if you must, 8 DIMMs (4 x 2GB for 2nd quad-set).


    While aimed at the 2009/2010s, any well done upgrade is worth studying.

    Good work Mike.


    Not that difficult was it?  Was lucky getting a 12" Torx driver found on a hardware clearance site in the US and had it mailed here to Australia.  Regarding memory suggest OWC.  Had 2x2GB modules fail, and as they offer a lifetime gurantee, had 2 new modules here in 14 days ~ brilliant.


    Found best upgrades after the CPU's was a SSD drive and an ATI Radeon HD4870 1GB graphics card.  All work smoothly with both Snow Leopard and Windows 7 Ultimate under Bootcamp.

    Memory Upgrade:


    I'm about to purchase 4x4gb ram from this website http://www.puremac.de/4-gb-fcm-ram-pour-mac-pro-pc5300-667-mhz-fb-dimm/a-20835/


    now I'm doing a research what is the best and effective way to install the ram. I used before this article http://homepage.mac.com/tribe3/.pictures/MemConfig.jpg but doesn't apply as I have now 4gb modules.


    right now, I have inside a mess with memory.

    4x original 512 Mb ram

    2x 2gb ram with the cheap flat alu sink

    2x 1gb ram withou any sink




    I have 4870 but the mac 512 mb version, I did not dare to buy the flashed version as at that time was even more expensive. have you got experience with 5770 1gb in mac pro 1.1?

    I do play occasionally  3d games, but as I have a pro Eizo monitor for my work I get sometimes lines during animation. but that is caused of slow ms response.


    Can not wait to have a Lion inside, hopefully all apps will be compatible.

    Has anybody that's upgraded the CPU in their MacPro 1,1 installed Lion or even 10.6.8 yet?


    I upgraded to E5345 and they've been running well for months until I upgraded to 10.6.8 and started getting lots of kernel panic reboots. I used TC to roll back to 10.6.7 and it's stable again. I even installed Lion on a fresh RAID array and that kernel panics too.


    I notice that the AboutThisMac app no longer works with Lion so back to having "unknown" CPUs. I've not tried putting my original CPU back in yet but that's the next step.

    Funny that you should mention this.  I've a MacPro 1,1 that was running with a pair of E5345s for almost 2 years now that was perfectly stable.  Since DP4 was so stable on my MacBook I decided to install DP4 on my MacPro and started experiencing a ton of KPs.  I figured it was the DP, but the KPs reoccured with RC and ultimately with the retail release.  I installed on a fresh drive from scratch using the DMG method and still KP.  Went back to 10.6.8 on a fresh drive and still KP.  Finally pulled the procs and replaced with the original 5150's that came in the machine and I've been running Lion without a single KP or reboot now for a week.  Of course, CPU bound tasks are now pokier but the machine is stable.


    I'd not tried to roll back to 10.6.7 specifically.  That's an interesting observation...

    I do not have a problem with 10.6.8 I recently upgraded processors + I have 22 GB ram. Did not have a crash, and all runs smooth.


    I'm not sure about Lion, I will wait for an update first as some people experiencing issues. I would like to know. If mac pro 1.1 is running faster on Lion. I do not have bluetooth in it. Anybody knows more?

    Lion works a treat on my upgraded Mac Pro 1.1 to Quad Core with X5355 processors.  Fast and rock steady.  Also Snow Leopard OS X.6.8 was very good also.  Upgrade presents no problems.


    Regarding Apple System Profiler not showing processor details, Google for a littlre utility called 'AboutthisMac.pkg'.  Fixed mine Profiler to read "2.66GHz Xeon Quad X5355 Processors."  Had to re-apply after Lion upgrade however.

    Very good!  do you use magic track pad? if yes could you let me know which bluetooth model have you got?

    scoopz Level 1 Level 1 (15 points)

    Harryb I had used the "AboutThisMac.pkg" to make it show the correct CPU details in 10.6.7 and it works in 10.6.8 but after installing a fresh copy of Lion "AboutthisMac.pkg" doesn't seem to do anything for me.


    mikecorp I've been using Bluetooth in my MacPro 1,1 for a few years with the Might Mouse, Magic Mouse and now with the Magic Trackpad as my only device. My Bluetooth module info is below.


    NOTE - When I fisrt installed the BT and WiFi cards (both bought from Apple) the Signal on both was quite poor. It turns out my antenna cables may have been labelled incorrectly. See this post http://forums.macrumors.com/showpost.php?p=2888144&postcount=14

    scoopz 'AboutthisMac.pkg' has now done the very same thing to me.  Downloaded a fresh copy, and the installer ran and has now reverted to ' Processor 2.66GHz unknown' .  Have posted a thread on this at mediafire and if there is ever any answer will post it back here.


    The problem with Airport leads being wrongly identified as cables 1,2 and 3 was well documented by Apple.  My Mac Pro 1.1 was purchased on 30 July 2007 as a Refurbished Model direct from Apple at Elk Grove ca and never had this problem so it must have been sorted out by Apple before then.

    Oky here is how to show Processors under the new Apple System profiler.


    Go to this link at MacRumours,





    post number 40, and download the CPUInjector file, listed as Download 1.1 when that page opens, and the Kext Utility file.  Double click Kext Utility and it opens to a box like looking icon.  Double click CPUInjector file or click Open and drag the file dated October 2009 to the desktop, and drag that file onto the KEXT icon and it will run.


    On completion About this Mac will read as:-



    Processor  2 x 2.66GHz Quad-Core Intel Xeon


    or whatever as the case maybe.

    I’ve recently upgraded my Mac Pro 1,1 with X5365 and have had a similar run of kernel panics as mentioned by Scoopz. Am also on Snow Leopard 10.6.8 and wondering what the issue might be so very interesting to read your experience (first I could find of anyone having a similar problem).


    I seem to have lessened the frequency of panics by upgrading Little Snitch. I had an older version installed that after a bit of reading I found had issues that could cause kernel panics. Still having issues on a daily basis at present though, so please share any additional info or solution you find! Guess my next step is to try find a 10.6.7 backup to play with…


    Would be really interested to hear what fan RPMs and CPU temps you have going on Scoopz.

    @allthepoo - I've not got any closer to finding a solution yet, I currently have 2 suspects:

    1. Apple Software RAID. I've only ever tried installing onto RAID arrays that have been created with Apple's Disk Utility so I'm going to break apart one of the RAIDs and try installing on a non-RAID drive. I noticed in my fresh Lion install that Disk Utility Repair Permissions bugs out when I try and repair the Lion drive it's on so it could be a suspect.

    2. My graphics card is the original 7300GT and the fact that the Lion install hung on "Installing" over and over when I had dual monitors connected makes me thing my GPU or GPU drivers could be at fault. After removing the 2nd 19" Dell monitor and just leaving the 30" Cinema display the installing flew threw. Yesterday I order an Apple 5770 upgrade kit from Apple. Granted it's not "officially" supported in the MacPro 1,1 but from what I've read it works perfectly, even with Lion (although the mini display ports might not work but I use DVI) and the card arrived today so I'll be trying that out this evening.


    I've created a post that I'm updating on my site about this regularly but I'll try and remember to post back here too with any findings.


    @harryb - thanks for the update on changing the CPU description in About This Mac, I'll give the new method a try.
