Technical specifications

Performance specifications as known at time of announcement

  • PC2700 CL2.5 Non-Parity DDR SDRAM memory upgrades: The '2700' is derived from 2.5 times 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) = 2667, rounded = 2700. This is the maximum data rate, the units are Mbps.
  • Non-parity mode organized as 16Mx64, 32Mx64, and 64Mx64 respectively.
  • Serial presence detect/decode.
  • 200-pin JEDEC/JEDIA standard SODIMM interface.
  • Gold-plated leads.
