At a glance

Help improve the overall performance of your NetVista A30, A30p, M42, and S42 systems with the 128MB, 256MB, and 512MB PC2100 CL2.5 Non-Parity (NP) DDR SDRAM Unbuffered DIMM (UDIMM) Memory upgrades. DDR SDRAM enables up to twice the performance of traditional SDRAM memory. Adding additional memory is a cost-effective way to improve your system's performance.


The memory upgrade offerings let you upgrade standard system memory capacity, improving overall system performance. Features and benefits include:

  • Test-proven 100% compatibility on systems indicated in the "Hardware Requirements" section
  • Meets stringent reliability standards for memory products
  • PC2100 Double Data Rate (DDR) Synchronous Dynamic Random Access Memory (SDRAM)
  • Maximum data transfer rate of up to 2,100 MBps
  • 184-pin Unbuffered DIMM (UDIMM) with gold-plated leads
  • Serial presence detect/decode functions
  • Limited warranty

Technical specifications

Performance specifications as known at time of announcement

  • PC2100 DDR SDRAM - The 2100 is derived from twice the front-side bus clock frequency (133 MHz x 2; data transfers can occur on both edges of the clock) times the module data width (64 bits / 8 bits/byte = 8 bytes) = 2,128, rounded = 2,100. This is the maximum data rate; the units are MBps.
  • Column Address Strobe (CAS) Latency (CL) of 2.5 (memory bus clock cycles)
  • Non-parity mode organized as 16M x 64, 32M x 64, and 64M x 64 respectively
  • Serial presence detect/decode
  • 184-pin JEDEC/JEDIA standard UDIMM interface
  • Gold-plated leads
