How to find your serial number in software
You can find your Mac's serial number in Apple System Profiler: Select the Apple Menu > About This Mac, then (depending on the version of OSX you are running) click the System Report button or the More Info button. This brings up System Profiler, and on the Hardware Overview that is displayed by default you should see your serial number, and be able to copy/paste it. The procedure does vary slightly between different versions of OSX.
If you can't boot your Mac
If your Mac is not working, the serial number is printed on the computer casing but the location varies. Here are the main locations of serial numbers on Apple computers.
Unibody MacBook Pro - Laser etched onto the base.
MacBook, Early MacBook Pro, PowerBook G4 - Inside the main battery bay. Remove battery to locate.
iBook (White) - Under the keyboard. To lift keyboard, pull back on the release tabs between the F-keys.
Intel iMac, iMac G5 - Underside of the foot/stand.
iMac G4, iMac G3 - Underside of the iMac.
Mac mini - On the underside of the Mac mini.
Mac Pro 2006-2012 - On rear of machine near graphics card ports.
PowerMac G5 - On lower chassis under side panel. To remove side panel, lift lever on rear of Mac.
PowerMac G3, PowerMac G4 - Label on the back of the Mac.
Your Mac's Model Identifier can be found in System Profiler. You can use the drop-down menus above to be taken to a page that displays upgrades specifically for your exact model.
This tool is also available on its own page, with a list of all Model IDs here.

PowerMac G5 Dual Core Upgrades
This
page covers all the upgrades we sell for the second of the two
major PowerMac G5 revisions - models made between October
2005 and 2006. Choose the type of
upgrade you are looking for from the tabs below.(Not the right
Mac? See here for
more PowerMac G5s, or here for
all Macs.)
If you want specific upgrades for your exact model, choose it from the Model ID links below, or enter your serial number here:
This page refers to the PowerMac G5s released in October 2005. These PowerMacs use DDR2 RAM (not normal DDR), have PCI-Express expansion slots (not PCI or PCI-X) and use dual-core G5 processors - the top of the range machine has dual dual-core processors, and was called a quad processor
machine by Apple.
For all previous PowerMac G5s you should refer to this page.
The dual core PowerMac G5 is the pinnacle of Apple PowerPC workstations, the dual-core CPU and the next-generation bus technology means that this will be a top-end workstation long after Apple has introduced Intel processors across its full range.
Apple's own specifications for this Mac can be found here.
How to Identify these Machines
The PowerMac G5s are easilly distinguishable from earlier machines by their size, shape, distinctive handles
and front and rear grills. If your machine looks like the picture to the right
you've got a PowerMac G5.
To distinguish between the latest PCI-Express dual-core PowerMac G5s and earlier ones, one way to tell is by the number of ethernet ports. Machines dealt with on this page have 2 x RJ-45 ethernet ports on the back. If you have only one RJ-45 socket, you need to refer to this page.
You can also tell the difference by opening System Profiler (Apple Menu > About This Mac, then click on the "More Info" button), then selecting Memory on the window that comes up and checking the speed column for any of the modules already installed. For this later PowerMac G5, it will start PC2-4200. Earlier non-dual core machines will start PC3200 or PC2700.
Other main distinguishing features are the number of processor cores - the earlier machines use single-core processors (although frequently were sold with dual processors), use DDR RAM as opposed to the newer DDR2 RAM in these machines. The machines on this page were all sold in or after October 2005.
Apple's own specifications for this Mac can be found here.
If you are still unsure you can contact us on 01223 833 412 or by email for
confirmation.
Memory Upgrades
The PowerMac G5 has 8 memory sockets. The machines can accept up to 16GB in RAM - (8 x 2GB).
Our memory is lifetime guaranteed and
comes with a full compatibility guarantee.
All RAM for the G5s must be installed in PAIRS - that means matched sizes and types for best performance i.e. to add
512MB of RAM you need 2 x 256MB Sticks.
Please note the RAM below is for the Dual Core (which is different to dual processor) PowerMac G5s only. If you have
a PowerMac G5 with 2 ethernet ports, this RAM is correct. If you have only 1 ethernet port, you need the RAM listed here.
There are none available.
Difficulty 1 / 5 - Very Easy
Open the side of the case by using the release bar at the rear of the machine.
Remove the metal grill and place to one side. Then remove the internal
plastic cover by lifting it up and out.
Next locate the two processor fans (on
one plastic runner) and remove outwards. This reveals the RAM sockets.
Place RAM into the sockets - RAM modules must be installed in matched pairs in this machine. The RAM is designed so it
cannot go in the wrong way around.
The PowerMac G5 came equipped with a Superdrive Optical drive loaded with a tray at the front of the machine. There
is no internal expansion for a second optical drive. It is possible to use an External DVD writer via USB 2.0 or FireWire
(FireWire is better since you cannot boot a PowerPC Mac from USB). The below drives will work with your Mac.
Blu-Ray is not fully supported in OSX. Disks can be mounted and read, but movie playback requires third party software.
