Technical specifications

Performance specifications as known at time of announcement

  • PC2700 DDR SDRAM Memory Upgrade: The 2700 is a figure derived from twice the memory-side bus clock frequency (166 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) = 2,656, rounded = 2,700. 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 128M x 64 respectively.
  • Serial presence detect.
  • 184-pin JEDEC/EIA standard UDIMM interface.
  • Gold-plated leads.
