Server Memory Upgrade

This 8GB DDR3 1600 ECC RDIMM module is built for IBM-Lenovo systems using part numbers 00D4988 and 00D4989. It targets administrators who need registered, error-correcting memory to maintain data integrity in server and workstation environments.

Thermals and Power

The module operates at the standard DDR3 voltage of 1.5V with a CAS latency of CL11. Registered buffering reduces electrical load on the memory controller, helping to keep power draw predictable and thermal output manageable during sustained workloads.

Build and Connectors

Major-brand chips populate a 240-pin DIMM PCB in a 1Rx4 configuration. The registered design requires a compatible server motherboard that supports ECC RDIMMs; consumer desktop boards will not accept this module.

Questions about this item

How do I install this 240-pin DDR3 RDIMM and what step is often missed?

Power off the server, open the chassis, align the notch on the 240-pin DDR3 RDIMM with the slot key, press firmly until both retention clips click, then verify in BIOS that the 8GB module is detected at 1600MHz with ECC active

What maintenance or replacement will this 8GB DDR3 1600 ECC RDIMM need over time?

No routine maintenance is required; keep air intakes clean so the 1.5V modules stay cool, and replace only if memory diagnostics report correctable ECC errors rising or a DIMM fails POST

What limit appears first when this 1Rx4 registered module runs sustained workloads?

The CL11 latency at 1600MHz and single-rank 1Rx4 organisation cap throughput before the 1.50V power envelope or thermal limits become a factor
