Upgrading the Mac Pro's CPU

Now that Apple has completed the switch to Intel based processors, upgrading your CPU is a much cheaper and more accessible option for Mac users. In the past, upgrading your CPU required visiting an Apple specific vendor and paying quite a bit for a processor since the demand was honestly quite low. Now, with the Mac Pro and any other Intel based Mac that has a socketed processor an upgrade is just as easy as a trip to Newegg.

The Mac Pro we ordered was the slowest 2.0GHz configuration, since we wanted to try and upgrade it to faster parts to see if it was possible. By opting for the slowest CPUs, you can buy a cheaper overall computer and simply throw in faster CPUs once they drop in price - assuming the upgrades work of course.

By far the biggest problem with upgrading the CPUs in the Mac Pro is gaining access to them. While Apple made it very easy to upgrade memory, storage and PCIe cards in the Mac Pro, getting access to the CPUs is considerably more difficult. The entire process would be made much easier if we were able to remove the memory cage, but as we mentioned in our last article the standoffs that the cage is screwed into would not remain in place while we unscrewed the cage. To make a long story short, we weren't able to remove the memory cage without stripping the screws that held it in place, so we had to come up with an alternative solution; luckily we were able to do just that.

The first step is to remove the heatsink cover, which has latches along its sides that the fan assembly and part of the memory cage hook up to. With the memory cage in place, your only option is to pull back on the memory cage to unlatch it from the heatsink cover and slowly pull/rotate the cover off. This process is made somewhat easier by removing the two screws that attach the memory cage to the motherboard, since it allows the cage to move a little more freely. Obviously you'll want to remove both memory risers before doing this, but simply pulling the cage back towards the rear of the case and pushing the heatsink cover in the opposite direction should let you unlatch it.

With the memory side of the heatsink cover unlatched, simply pull it away from the fan assembly being careful not to break the latches. After you've done this, the Xeon heatsinks should be exposed.

    Assuming you want a workstation capable of accessing 16GB of RAM (and using two processors), your options are a bit more reduced. There was an article on Anandtech, and the Mac Pro (the most expensive) was just a couple of hundred dollars more expensive than the sum of its components (and operating system I think).

    And which one will run cooler and be completely silent when you push it? Ah, the Mac will. High quality build, excellent components, superior GUI: $2,500. Peace and quiet while working: priceless.

    You do realize that the Mac Pro comes with all the drive sleds... you can add the WD5000KS drives yourself later. You can also add memory yourself.

    Doing it this way... ordering the Mac Pro with 2 x 512MB RAM and 1 500GB drive costs: $3009.
    Add in the RAM you quote: 4 DIMMS at $680 + 2 WD5000KS at $189 @ = $4067
    Total difference then is a mere $256.

    You are still missing firewire 400 and 800 and firewire target disk mode.
    The power supply in the Mac Pro is much beefier.
    Windows XP 64 bit is a mess.

    And then we get to the fact that you are comparing a retail price to a non-retail price, comparing a bunch of parts to a fully assembled system, and you are leaving out the shipping issue altogether. Certainly, it is possible to pay $4,909 + tax for the Mac Pro. It is also very possible to pay far less.

    The arguments in this regard are less about Apple and more about homebuilt vs. Tier 1 vendor. You might as well be comparing against IBM Intellistations, Sun Ultra 40's, or HP xw8400's. You'd appreciate it not being a homebuilt when you have to manage many of these over time.

    A 5% discount on the base system + the extra RAM and drives added later is $3917, or $106 difference. I usually get bigger discounts than that 5% on systems like this.

    In the end, if you aren't interested in using Mac OS X at all, the Mac Pro is probably not for you. It is the complete suite... from the hardware (including the nice boot menu, target disk mode, etc), the software (Mac OS X, iLife, platform user experience, etc.), solutions integration (Xsan costs $999 vs. ADIC StorNext at $4k for SAN filesystems), on through to applications (Final Cut Studio, Shake, etc.).

    Windows XP Professional supports two processors (cores) out of the box. Put a Windows 2003, and see where you get...
  • Sunrise089 - Tuesday, September 12, 2006 - link

    and even that "home built" price was without a case, OS, or power supply.
  • Calin - Wednesday, September 13, 2006 - link

    As for the OS, you could "migrate" your Windows XP - with one small problem - XP is 1-2 processors only, this configuration would have 4 cores...
    So, add another ... for Windows 2003
  • JarredWalton - Wednesday, September 13, 2006 - link

    Sorry, but that's wrong. XP is 1-2 *sockets* only. XP home will work with a dual core or even quad core CPU just fine, and XP Pro works with all 2S workstation setups without difficulty. Microsoft modified the way they count CPUs when dual core first came out.
