Server Memory Module

This A-Tech module is a 4GB DDR3 1866MHz ECC RDIMM built for IBM-Lenovo part numbers 00D5028 and 46W0688. It targets administrators upgrading or repairing compatible server and workstation platforms that require registered memory with error correction.

Build Integration

The stick uses a standard 240-pin DIMM form factor and runs at the DDR3 standard voltage of 1.50V with CL13 latency. Its registered design places a buffer between the module and the memory controller, reducing electrical load so larger memory populations remain stable. The 2Rx8 organisation fits two ranks into a single slot, freeing additional DIMM positions for further capacity expansion.

Suitability

This module suits IT teams maintaining legacy DDR3 infrastructure where ECC and registered operation are mandatory for data integrity. It is not appropriate for systems that accept only unbuffered UDIMMs, for platforms limited to lower DDR3 speeds, or for builds that require higher-density modules beyond the 4GB single-stick capacity.

Questions about this item

Does the CL13 latency become a bottleneck during sustained server workloads?

CL13 is the rated CAS latency for this DDR3 1866 module; sustained throughput depends on the platform's memory controller and how many ranks are populated per channel.

How much heat does a registered 1.5 V DDR3 DIMM produce when running continuously?

Registered DDR3 at 1.5 V typically stays within standard JEDEC thermal limits; adequate chassis airflow is recommended for 24/7 operation.

Which motherboard slot and chipset combination is required for this 240-pin ECC RDIMM?

This module fits a DDR3 240-pin RDIMM slot on a server or workstation board that supports ECC registered memory; verify the system's qualified vendor list before installing.
