History

This group of machines are all based on the Sawtooth architecture, and it includes the G4 AGP original and the Gigabit Ethernet series of single processor machines. There are also dual processor Gigabit Ethernet machines, which are dealt with on this page.

These units brought the G4 7400 series of CPUs into the Mac line up. The first machines came out in September 1999 and stopped production October 2000. They shipped with a 16MB AGP Rage128 graphics card, and a different CPU socket from the preceding G4 PCI Graphics.

These machines all shipped with DVD-ROM or DVD-RAM and had two USB ports and two FireWire ports.

These are excellent machines, and can be significantly upgraded for a very reasonable amount of money.

MacUpgrades has an article online which goes into detail about recommended upgrades for the PowerMac G4 AGP.

How to Identify these Machines

This page deals specifically with single processor 100Mhz bus speed PowerMacs with an AGP graphics chipset. These machines are part of the ranges known as the AGP Graphics, and Gigabit Ethernet PowerMac G4s. Most Gigabit Ethernet machines had dual processors, but these machines are dealt with on this page. These PowerMacs can be fairly easily distinguished from other G4 towers.

They are in a graphite coloured case, unlike the silver case used on the G4 Quicksilver and above.

The rear of these PowerMacs have two audio sockets which are aligned vertically from the bottom of the port panel.

You can also check the components inside the case:

Turn the machine off and open the side of the case. Internally all G4 AGPs have four memory sockets (black in line sockets - see picture) towards the top of the case.

The PowerMac G4 PCI Graphics also have four RAM slots, but the audio ports on the back of the machine are aligned horizontally. Graphite coloured PowerMac G4s later than the Gigabit Ethernet range have only three RAM slots.

You will notice four differing expansion sockets, some will be used. The first of these is a brown socket which is called AGP. If your machine does not have AGP it may be a G4 PCI Graphics. The other 3 sockets are for PCI Expansion cards. There is space for a number of internal hard drives to the rear of the machine.

If you are still unsure you can contact us on 01223 833 412 or by email for confirmation. If you want to upgrade but aren't happy to install your upgrades then we can help. Simply ask our engineers for further details.

Memory Upgrades

The PowerMac G4 AGP Graphics has four memory sockets, any of these sockets can take up to a 512MB module.

When they were released, these PowerMacs could only address a maximum of 1.5GB of RAM, despite the fact that 2GB could be physically installed. However under OS 10.3 (Panther) and above these machines can address the full 2GB.

There are none available.

Difficulty 1 / 5 - Very Easy

Open the side of the case, with the machine turned off, and place the RAM into a socket. The RAM is designed so that it cannot go in the wrong way around.

Apple's instructions can be found here.

If you are unsure please call or email our team.

CD/DVD/Blu-ray Drive Upgrades

An internal CD/DVD drive would replace your existing optical drive. There are also external FireWire and USB options (FireWire highly recommended for this machine).

Any replacement internal 5.25" IDE CD unit will install into this PowerMac, and should work to read data. However, unless there is an Apple ROM on-board the CD unit, the computer cannot be booted from the CD, and the unit will not integrate with Finder burning and Apple software like iDVD. Burning can still be accomplished by third party software such as Roxio's Toast.

Look for the footnotes on any internal drive listed below, to see if there are any issues as described above.

Internal Hard Drive & SSD Upgrades

The PowerMac G4 AGP can can take internal IDE hard drives of sizes up to 120GB. Up to two extra drives can be added alongside your existing hard drive - a straight replacement is obviously possible as well.

If you want to use a larger hard drive you will need to use a SATA drive and install a SATA controller into a PCI socket. See the expansion cards section at the end of this page for details on available cards.

If you don't want to fit a new hard drive yourself, you can take advantage of the MacUpgrades Installation Service. Add the installation service from the list below to your cart along with your chosen hard drive. We can also clone your existing hard drive onto the new one, simply add the Clone Original Hard Drive service below to your cart.

Once you have booked the service, send your machine to us, we will carry out the work and return it to you. Alternatively, we do offer a Collection Service with our courier, please see here for details.

Graphics Cards and Displays

Your PowerMac G4 AGP Graphics has one available AGP socket for upgrading your video capabilities. You also have three 33MHz PCI slots, which can take a second graphics card - however the AGP socket is superior and should be used for the primary graphics card.

High-end graphics cards are useful for 3D applications and games - also a lot of the effects within OSX use the graphics card, so upgrading the card will make your OSX desktop smoother and nicer to look at.

There are none available.

Difficulty 1 / 5 - Very Easy

Install any supplied software and turn off the machine.

Open side door and locate the (brown) AGP socket. Remove holding screw and remove the original card.

Insert the new card, and secure with the screw.

If you are unsure please call or email our team.

Expansion Card Upgrades

Your PowerMac G4 has to three PCI sockets for connectivity expansion. Since the machine was released FireWire 800, USB 2.0, faster internal IDE controllers, faster wireless and wired connectivity, and much more, has become available.

With the use of PCI expansion cards, you can update your machine to use current spec connectivity types. Please note that some cards have an operating system version requirement - see the notes in the table below for any that apply to this machine.
