ThinkCentre 1GB and 2GB PC2-5300 DDR2-667 UDIMM Memory - Overview
Features and specifications

The ThinkCentre 1GB (73P4984) and 2GB (73P4985) PC2-5300 DDR2-667 UDIMM Memory offers:

  • Maximum data transfer rate of up to 5,300 MBps
  • 240-pin UDIMM with gold-plated leads
  • Serial presence detect and decode functions

Notes:

  1. PC2-4200 and PC2-5300 memory can coexist on one system, but will operate at PC2-4200 speed.
  2. Data transfer rate may vary based upon many factors and is often less than the maximum possible.

 

Performance specifications
  • PC2-5300 DDR2 SDRAM memory upgrades -- The 5300 is a figure derived from twice the memory-side bus clock frequency (333 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) = 5,300. This is the maximum data rate; the units are MBps.
  • Column Address Strobe (CAS) Latency (CL) of 5 (memory bus clock cycles) for PC2-5300 memory.
  • Non-parity mode organized as 32M x 64, and 64M x 64, and 128M x 64 respectively.
  • Serial presence detect with Serial EEPROM.
  • 240-pin JEDEC/EIA standard UDIMM interface.
  • Gold-plated leads.
