NOTE!
As PC2100 is getting increasingly difficult to acquire, PC3200 can be used instead. Using PC3200 may or may not increase the performance of your model, as some models may underclock it to their respective original DRAM speeds.

PC2100

This is DDR SDRAM at 266 MT/s in a 200-pin SO-DIMM form-factor. DDR266 may also be interchangeably referred to as PC2100.

  1. Attained via two 2Rx8 1GB DDR non-ECC SO-UDIMMs, not possible with 1Rx8 1GB DDR non-ECC SO-UDIMMs. (if they exist)
  2. The Radeon IGP 330M graphics+memory controller is incapable of using DRAM modules utilizing 64MB chips, which means it's stuck with 32MB-based DRAM modules. Therefore, only low-density DRAM modules such as a 2Rx8 512MB DDR non-ECC SO-UDIMM will work.
