Introduction
What you need
Step 1
Case
- The Power Mac G4 MDD: the last, and the fastest G4-based Mac. This computer boasted up to a Dual 1.42GHz PowerPC G4 CPU (though I have a single 1.25GHz).
- Two USB 1.1 Ports
- Assorted Audio
- Video (ADC & DVI)
- Networking (RJ-45 Ethernet/56k Modem)
- Some later model MDD’s (such as the dual 1.42GHz) Have a FireWire 800 Port Here:

Step 3
RAM
- The ram is between the graphics card, and the CPU, and removal is simple. Push the tabs down on both sides, this will free the ram, then lift it out.
- The MDD uses a maximum of 2GB PC2700 DDR RAM (512MB X4) and has 4 slots.

Step 4
Graphics Card
- The Power Mac G4 MDD uses a Mac-Compatible AGP Graphics card with ADC, And DVI or VGA.
- My mac has a NVIDIA GeForce4 Titanium with 128MB of video ram, this was an excessively large card, for some reason.
- Start by removing this Phillips screw.

Step 5
- Using a flathead screwdriver, spudger, or your finger pull this tab towards you, and lift the card out.
- The “excessively large” NVIDIA GeForce4 Titanium 128MB. This was one of the most powerful cards on the market when this computer was released, now, there are flashed cards such as the Radeon 9700 Mac, but this is the most powerful AGP ADC supporting card, great for gaming, Photoshop, and other 3D intensive applications.
