    When purchasing memory to install into the computer, select SDRAM meeting the following specifications and guidelines:

    • Double Data Rate2-Synchronous Dynamic Random Access Memory (DDR2-SDRAM)
    • PC2-4200 (DDR2-533 CL4) SO-DIMM
    • 533MHz

    NOTE: CL4 refers to the Column Address Strobe (CAS) Latency of the RAM. CL4 indicates that the computer will wait 4 clock cycles between a request for a unit of information in memory and the receipt of that information for further processing.
