  • TypeRAM Module
  • ECC Chipkill protects data integrity in critical workloads
  • Registered signal processing stabilises high-density server configurations
  • 667 MHz DDR2 speed matches PC2-5300 platform requirements
  • Two 2 GB modules deliver 4 GB total capacity
  • 240-pin DIMM fits standard DDR2 server slots

4 GB DDR2 ECC Registered DIMM

This IBM memory kit supplies 4 GB across two 2 GB modules built to the DDR2-667 standard. ECC Chipkill error checking and registered signal processing make it suitable for servers that require data integrity and stable operation under sustained loads.

Thermals and power draw

DDR2 SDRAM at 667 MHz runs at modest voltage and generates limited heat in typical server workloads. The registered buffer reduces electrical loading on the memory controller, helping keep system power draw predictable during normal use.

240-pin DIMM form factor

The 240-pin DIMM layout fits compatible DDR2 server boards without adapters or extra brackets. No software, cables or cooling accessories are included, so installation is limited to seating the modules in the appropriate slots.

Questions sur cet article

How do I install the 240-pin DDR2 DIMM and which step is often missed?

Align the notch with the slot key, press straight down until both retention clips click, and verify the ECC Chipkill registered module is recognised in the BIOS memory map.

What maintenance or replacement will the 4 GB DDR2 kit need over time?

No routine maintenance is required; if a 2 GB module fails, replace the pair with another matched DDR2-667/PC2-5300 registered ECC set.

What limit appears first when the 667 MHz modules run under sustained load?

The DDR2-667/PC2-5300 bandwidth ceiling and registered signal latency become the bottleneck before thermal throttling occurs.
