iMac G5 Original Memory DDR400

  • Tech Specs
  • Shipping

The original iMac G5 has two memory slots, which can hold a maximum of 1GB in each. This memory type is called DDR400 184pin DIMMs. Memory does not have to be installed in matched pairs, but a performance gain is realized if identical sized modules are in both slots. Pairing modules enables Memory Interleaving, which allows your memory controller to address both modules as a single 128bit memory bank.

Stacked v. non-stacked chips:
A module built from stacked chips takes two RAM wafers and stacks them on top of each other. This makes it possible to build a large module (like a 1GB DIMM) using cheap low density parts. Stacked chip modules are bad because they draw more power, and have inflated error rates caused by heat build-up. Ramjet uses the highest quality non-stacked IC chips.
