History

The PowerMac G4 "PCI Graphics" was announced in September 1999, along with the PowerMac G4 "AGP Graphics" - although these PCI Graphics machines started shipping earlier, and would generally be considered the first PowerMac G4s.

These PowerMacs are based on the same Yosemite motherboard as the PowerMac G3 "Blue & White" - the G4 PCI added a Motorola MPC 7400 processor to an already successful machine.

Apple billed the 7400 as a "Super Computer on a chip", due to the fact that it was capable of executing more than a billion instructions per second (a gigaflop). Much of the 7400's speed increase was due to a new set of instructions, which were executed by a new unit on the chip. Motorola refers to this new unit as the "AltiVec" unit, while Apple publicly refers to it as the "Velocity Engine." The Velocity Engine vastly increased the speed of many common processor-intensive tasks.

The PowerMac G4 PCI Graphics is an upgradeable machine, however it does suffer somewhat from its older motherboard architecture when compared to the AGP Graphics PowerMac G4.

Apple's own specifications for the PowerMac G4 PCI Graphics can be found here.

How to Identify these Machines

The G4 PCI Graphite can be easily distinguished from other G4 PowerMacs.

The rear of the G4 has two audio sockets which are aligned horizontally from the bottom of the port panel. The only other Graphite PowerMac with horizontally aligned audio sockets is the PowerMac G4 Digital Audio (the DIgital Audio however has only three RAM slots, see below).

You can also check the components inside the case:

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

The PowerMac G4 AGP Graphics, and PowerMac G4 Gigabit Ethernet also have four RAM slots, but the audio ports on the back of these machines are aligned vertically. Graphite coloured PowerMac G4s later than the Gigabit Ethernet range have only three RAM slots.

You will notice four differing expansion sockets. All of these sockets should be cream in colour, but one of them will be segmented into two - this is a faster slot and will probably contain your graphics card. The other 3 sockets are for PCI Expansion cards.

If you have a brown socket instead of a segmented cream one, you may have an AGP Graphics PowerMac G4 instead.

Apple's own specifications for the PowerMac G4 PCI Graphics can be found here.

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 PCI Graphics have 4 RAM slots, each of which can take up to a 256MB module, for a maximum of 1GB.

INSTALLATION - RAM in a PowerMac/Mac Pro£15.00 + vat (£17.62)
Kingston PC100 SDRAM DIMM 256MB£38.16 + vat (£44.84)

Any fitting information below is intended as a guide before purchase ONLY, when fitting these products you should refer to the original manual for your computer, and any instructions that come with the item. Please see this page for more information, or here for information on our fitting service.

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.

If you are unsure please call or email our team.


CD & DVD 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.

INSTALLATION - Internal CD/DVD Drive in a PowerMac/Mac Pro£15.00 + vat (£17.62)

Any fitting information below is intended as a guide before purchase ONLY, when fitting these products you should refer to the original manual for your computer, and any instructions that come with the item. Please see this page for more information, or here for information on our fitting service.

Difficulty 2 / 5 - Easy (internal)

Turn off the machine and open the side door.

Remove the front panel of the CD drive, which is secured by two clips.

Remove two small Phillips screws and gently move the CD caddie forward.

Disconnect all cables and replace with the new unit. Then install your software.

If you are unsure please call or email our team for details.


Internal Hard Drive Upgrades

The PowerMac G4 PCI 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.

If installing as a second drive then change the jumper setting to slave, and add the drive above the existing hard drive.

Connect power and data cables, and initialise the disk.

If you are unsure call or email our team.


eSATA Storage

This Mac can have an eSATA controller card added into an expansion socket - allowing it to control an array of eSATA drives.

For an explanation of what eSATA is, please see our eSATA FAQ. To see our full listing of eSATA products, please see the eSATA category.

eSATA products compatible with this Mac can be found on this page - eSATA controllers can be found on in the expansion cards section, eSATA enclosures are with the external hard drives, and SATA hard drives are listed with the internal hard drives.


Graphics Card Upgrades

Your PowerMac G4 AGP Graphics has one available 66MHz PCI socket for upgrading your video capabilities. You also have three 33MHz PCI slots, which can take a second graphics card - however the 66MHz PCI 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.

INSTALLATION - Graphics Card in a PowerMac/Mac Pro£15.00 + vat (£17.62)

Any fitting information below is intended as a guide before purchase ONLY, when fitting these products you should refer to the original manual for your computer, and any instructions that come with the item. Please see this page for more information, or here for information on our fitting service.

Difficulty 1 / 5 - Very Easy

Install any supplied software and turn off the machine.

Open side door and locate the (cream coloured, segmented into two) 66MHz PCI 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.
