System-Specific DDR1 Kit

This 2 GB kit contains two 1 GB unbuffered DIMMs built for the Apple Power Mac G5 2.0 DP (PCI-X). Each module runs at 400 MHz with CL3 timings and a 2.6 V operating voltage. The 184-pin form factor matches the original memory slots exactly.

Ideal for G5 Restorations

Owners restoring a Power Mac G5 2.0 DP (PCI-X) to factory specifications will find the correct density, speed and voltage in this package. Buyers who need ECC registered memory or a different pin count should look elsewhere.

2.6 V Operating Voltage

The 2.6 V requirement is the critical specification; the host system must supply this voltage for stable operation. Confirm the motherboard supports 2.6 V DDR1 before purchase.

Questions about this item

Will the 184-pin DIMMs fit the Power Mac G5 2.0 DP memory slots?

Yes, the 184-pin DDR1 DIMMs match the Power Mac G5 2.0 DP slot design exactly.

How do I install the two 1GB sticks correctly, and what step do people miss?

Power down, open the side door, eject the plastic levers on each slot, align the notch on each 184-pin stick, press firmly until both levers click shut, then close the door.

Will these unbuffered non-ECC modules need any firmware updates or battery replacements later?

No firmware or battery work is required; the sticks are passive components with a limited lifetime warranty from the brand.
