2GB DDR400 DIMM for Apple Power Mac G5

This 184-pin DIMM delivers 2 GB of DDR400 memory rated at PC3200 standard. It is built for the Apple Power Mac G5 Dual 2 GHz SuperDrive (M9455LL/A) notebook and similar systems that accept DDR SDRAM at 400 MHz. The single-module kit installs directly into a compatible DIMM slot.

Suitable for legacy Mac upgrades.

Owners of the specified Power Mac G5 model can use this module to restore or expand system memory. Builders working with 260-pin SODIMM slots, DDR4-2400 speeds, or any platform newer than DDR400 should look elsewhere. The form factor and signalling are incompatible with current laptop memory standards.

2 GB capacity handles light multitasking

The module provides enough headroom for basic macOS operations and period-correct applications on the target hardware. It reaches its limit quickly with modern browsers, virtual machines or large media files. Systems requiring more than 2 GB per slot or higher bandwidth than PC3200 will need a different memory generation entirely.

Questions about this item

Does my system need a DDR400/PC3200 DIMM slot to use this 2 GB module?

Yes, the module is a 184-pin DDR400 DIMM rated at 400 MHz and requires a matching DDR400/PC3200 slot.

Will this DDR400 DIMM run at 400 MHz if installed alongside slower DDR memory?

The system will clock all modules to the speed of the slowest installed memory, so this 400 MHz DIMM will down-clock to match slower DDR sticks.

How can I confirm the module is recognised at 400 MHz after installation?

Check the memory speed reported in the BIOS or a system-information utility; it should show 400 MHz (DDR400/PC3200) for this 2 GB DIMM.
