    OWC strongly recommend TRIM be not enabled with their Mercury Extreme SSD as they use Sandforce 'garbage collection' to keep the drive in tip top condition.  Regarding the CPU's appearing as unknown, look up this link:-

    Go to post number 40, and then download the 'Download 1.1' file and the kext utility file.  Open the Download 1.1 and drag to the desktop the CPUInjector.fle, double click and open the Kext Utility.  I box like icon appears, and drag the CPUInjector file and drop onto the box.  Apple System Profiler will then read   'Processor 2 x 2.66GHz Quad-Coore Intel Xeon'.

    Thanks for the reply. I wonder if anyone else knows the answer.

    A few things guys, ive been reading along with you guys after my earlier contrabution, i ended up with a  2.8ghz "octo core" 3,1 '08  model. a few things:

    A. what ever model SSD you get, you are going to be limited by the sata II 3gb/s which is more or less about 300MB/s, if you have an older model mac pro. so sorry your not gonna get 400+MB/s speed

    B. even if they do make a sata 3 6gb/s card(which i would so buy) our pci card slots only go up to about 5GB/s

    C. I ended up with an OWC 3g ssd, 60 GB means that i used symlinks to keep things like my steam lib, itunes lib and other things on other drives. i think this was a really good option

     

    Heres my recomendation for all those out there worried about lion

    1. Buy a new SSD (if you dont already have one) 60-120 GB or so should do

    2. clone your boot drive onto it, i would recoment carbon copy cloner

    3. boot from it and download and install lion

    4. if you dont have any problems, congrats, your running lion, and you have a really fast boot drive, if you do have a problem, just reclone your old boot disk onto your SSD and congrats, even though your not running lion, you still sped up your mac pro

    hope all this helps

    the http://en.wikipedia.org/wiki/List_of_Intel_Xeon_microprocessors#.22Clovertown.22 _.2865_nm.29 doesn't list "'QWTH' version of the X5365" spec code??? Not sure if that means that there isn't such a beast, but I'd double check the code.

  • harryb Level 1 Level 1 (30 points)

    QWTH usually indicates an engineering sample and the ones I have seen are still stepped SLAED or SLAC3.


    And for what it is worth Benjamin, OWC techniocians strongly advise against cloning, which copies any defects from a platter drive ton the SSD.  They brecommend clean system install and then use Migration Assistant to transfers applications, network settings etc. acroos, and the current system software, or Combo, update.

    no kernal panic so far on Mac Pro. I did test games, OLD age 3, COD..etc all runs fast and quietly.

    I read the post about the computer crashes, none of that happened, I run 7.1 I made sure I get the latest updates first before any other tweeks.

     

    -Just update everything to latest version. If you run, vuze you need to update it + Java.

    another thing I noticed. If you have a Logitech mouse (i have mx400), you need to get newest soft, because mine was crashing Sys. preferences. I still have to check my wacom tablet.

     

     

    I updated an Imac (2010) today and I had problem to get Java to work. On mac pro I got automatic update, but not in Imac. I had to download it manually works after restart, Safari on Imac was crashing, took me 30 minutes to get it to work.

     

    Now all runs fine.

  • brettallica Level 1 Level 1 (0 points)

    Thanks for your replies, harryb and Kim Hansen1.

     

    harryb, it looks like you might have a litle bit of knowledge on this subject. Would you say that it is safe to purchase the engineering samples and then use them in the Mac Pro 1,1? Would there be any possible bad outcome of this?

  • harryb Level 1 Level 1 (30 points)

    Engineering samples arel ike beta versions of the hardware.  They are provided to mabnufacturers for testing much like beta software is available for download and assessment.  Here Wikipedia explains it much better:-

     

     

    http://en.wikipedia.org/wiki/Engineering_sample

     

    Have not personally installed these samples, always matched pairs of X51xx and X53xx CPU's but other I know have purchased them when nothing else was available, particulalr for the X5365 3GHz version which are rarer than the 2.66 and of course much dearer.

     

    Have heard of no negative reports on these samples, but still and all would look for matched pair of non-engineering samples personally.  May take a few more weeks but better to be safe than sorry.  Apple does not support CPU upgrades for the obvious reason so perhaps these posts may vanish somewhere along the line.

  • brettallica Level 1 Level 1 (0 points)

    Thanks for the reply. I appreciate it, and I'm guessing/hoping others do, too.

     

    It sounds like you have a lot of experience in this modification, so I have yet another question for you: can a person in my shoes (1,1 with original dual 2.66 GHz processors) simply opt, be it temporarily or permanently, to remove those original processors and replace only one of them? I ask in the context of those who don't want to drop a ton of cash on the upgrade at one time by buying two processors in one purchase. Like, if they wanted to only buy one X5365 for now, then buy another later as the budget afforded it. If this is an option that will work, I would strongly consider it for my own setup. Of course I know by now that you have to have matching processors for when you do have two in there, so one would have to be careful when buying that second one, but if that works it would be a great way to ease into the mod from a financial standpoint, yet still get your foot in the door with the quad.

  • harryb Level 1 Level 1 (30 points)

    Breett that is not something I would recommend doing running the Mac Pro with one 5300 processor and one 5100.  There are reports of folks doing this, but suggest the best way is to purchase a matched pair when you want to go this way.  Matched pairs come with identical serial numbers and of course have the same stepping.

  • brettallica Level 1 Level 1 (0 points)

    Thanks, harryb. I think I must've been a bit unclear in my message, though. Sorry about that. What I had actually meant was removing both original processors, and then only putting in one quad. The original processors would never go back in; not one. That means the computer in this state would only have one processor powering it: the new quad.

     

    Then, when the finances allow, buy the second quad processor. Obviously in this case you would have to make sure that you get same stepping.

     

    Is that doable?

  • stevefromtempe Level 1 Level 1 (5 points)

    @mikecorp how did you fix these problems

     

    "1- got error during install and reboot, NTFS tuxera did not work anymore.  Solution -> Upgrade all OTHER system preferences!!!!

     

    2-About this mac will show you Unknown Processor, App "about this mac 2" did not work for me. Solution -> Find the kext utility described by Harryb bit earlier in this discussion. Works after restart.

     

    3-I had several crashes of Safari, Mail but not a big concern

     

    4- I run the geekbench after 7.1 upgrade. ;( well do not know what it means, but my score is less then before."

     

    As you posted b4 you have had these problems. But, some things i just have never had to do for instance  "Upgrade all OTHER system preferences!!!!" i solved how to do number 2 and how did you fix number 3. Thx hope you reply soon

  • harryb Level 1 Level 1 (30 points)

    Okay Brett misunderstood sorry mate.

     

    Running one CPU is not something I would do personally, but having said that Google shows many reports of folks doing just that, particularly this link and the thread by Purple Patch:-

     

    http://www.insanelymac.com/forum/lofiversion/index.php/t123604.html

     

    Dell,HP and IBM of course offer single CPU X5355/5365 so there would be not great danger in it that I could see. Only thing to be doubly sure of when it comes time for the additional CPU< get the same step model.

     

    Be interesting to see performance differences between the 2.66GHz Dual Core and the X5365 3GHx Quad with only one processor.


    Steve pleased you got the Kext Utility up and goind.  Does it shows 'Processors 2 x 2.66GHz Quad-Core Intel Xeon'?

  • stevefromtempe Level 1 Level 1 (5 points)

    STATUS UPDATE! So Mikecorp i have finanally done the upgrade i got the cpu's today and all is well more then excpected so far i am running 10.7.2 11C40 and have a RAID, Little Snitch, and all other things i am running that may have caused a KP. So far so good but the only problem i see potentially is the Artic Silver #5  and the heat temp is idling at 36 C and 97 F hopeflly this changes soon. Otherwise all is well "knock on wood" for no KP's

  • mikecorp Level 1 Level 1 (0 points)

    Great Steve

     

    -. My CPU's running 40C, but that should be normal.

     

    -. I still run 10.7.1  and having issues, with Perian, Quick time stoped to play, divx, avi, wmv ...etc I use Mplayer instead until it will get fixxed.

     

    -.windows booted fine, but did not try the new bootcamp update yet.

     

    Have you got Raid card or running soft? Any strange ticking?
