PowerBook G4 Aluminium (12, 15 & 17-inch, 2003–2005) RAM Upgrade

Mac Repair London carries out a RAM upgrade on the PowerBook G4 from our Central London workshop, for home users and businesses.

The 15 and 17-inch PowerBook G4 have two SO-DIMM slots (PC2700 or PC2-4200 depending on revision) and top out at 2GB. The 12-inch has 256MB or 512MB soldered to the board plus one slot, for a maximum of 1.25GB or 1.5GB. The RAM door is under the battery on the 15 and 17-inch, so it’s a quick job. We supply matched, tested modules, and a known quirk is that some later 15-inch models reject one slot after a board fault, which we check for during fitting.

Signs it needs a RAM upgrade

• Bottom RAM slot not recognised (a known board fault on some models)
• Slowness with Leopard and modern web pages
• Random freezes from a failing original module

How we do it

We read your exact model identifier first, because Mac memory is fussy about speed and type, and the wrong module can cause beeps at start-up or random crashes. We fit matched pairs where the model benefits from dual-channel memory.

After fitting we run an extended memory test and check that the full amount shows in System Information, so there are no surprises later.

Before you bring it in

If the Mac has ever beeped at start-up or reported memory errors, tell us, as a faulty existing module changes what we fit.
