DIMM1
*
* The PCV-RX450/PCV-RX460 is shipped with 128 MB. SDRAM is expandable to 512 MB. Computer
SDRAM is unbuffered DIMM, specification Rev. 1.0 or later. Supports SDRAM memory. Does not support
EDO memory or buffered DIMM memory. Memory can be installed in either socket. Memory size can vary
between sockets. DIMMs can be single- or double-sided. DIMMs must be 3.3 V unbuffered 4-clock, 64-
bit or 72-bit 133 MHz SDRAM modules.
