Targeted upgrade for Apple Power Mac G5 (Dual Core

This 2GB kit contains two 1GB unbuffered DIMMs built to the DDR2 533 (PC2 4200) standard with CL4 4-4-4 timings at 1.8V. The 240-pin modules use major-brand chips and carry a limited lifetime warranty from Computer Memory Solutions. Package includes both sticks ready for installation.

Suits owners restoring

Buyers who need ECC registered memory, a different pin count, or higher density modules for another platform cannot use this kit. The product is validated only for the Apple Power Mac G5 (Dual Core 2.0Ghz) and is not tested for any other system.

240-pin DDR2 533 (PC2 4200) interface decides fit

The motherboard must accept 240-pin unbuffered non-ECC DIMMs at 533 MHz with 1.8V operation. If the target computer uses a different memory generation, pin layout, or voltage, these modules will not seat or function.

Questions about this item

Does my Apple Power Mac G5 (Dual Core 2.0GHz) need all 8 DIMM slots filled to use this 2×1GB kit?

No. The kit installs in any two of the eight available slots; the system runs with a partial population.

Can I keep my existing PC2-4200 modules installed while adding this pair?

Yes. Both run at DDR2 533 with 4-4-4 timing, so the memory controller will operate them together at the same speed.

How do I confirm the Mac recognises the full 2GB after installation?

Open About This Mac or System Profiler; the memory section should show two 1GB DDR2-533 DIMMs totalling 2GB.
