4GB DDR3 1866MHz ECC RDIMM

This A-Tech module provides 4GB of registered ECC DDR3 memory at 1866MHz with CL13 latency and 1.50V operation. It uses a 240-pin DIMM form factor and a 1Rx4 rank configuration built with major brand chips. The part serves as a direct replacement for several HP server part numbers including 708637-B21 and 712381-571.

Suited for HP server upgrades needing registered ECC

Administrators maintaining compatible HP ProLiant or workstation systems that require DDR3 1866MHz registered ECC memory can install this module to restore or expand capacity. Builders whose platforms demand unbuffered UDIMM, SO-DIMM, or a different DDR generation cannot use this registered DIMM.

Registered ECC with 1Rx4 organisation

The single specification that decides fitment is the registered ECC 1Rx4 organisation combined with DDR3 1866MHz speed and 240-pin form factor; only systems explicitly qualified for this exact module type will accept it.

Questions about this item

Will the single-rank 1Rx4 ECC RDIMM need replacement under normal server workloads?

The module is built with major-brand chips and tested to stringent standards, so it typically runs for the life of the server without needing replacement.

Does the CL13 latency at 1866 MHz limit throughput during sustained heavy loads?

CL13 at 1866 MHz delivers the rated PC3-14900 bandwidth; the registered buffer and ECC keep data integrity steady even under continuous demand.

How much heat and power does the 1.5 V DDR3 DIMM produce when running all day?

Operating at standard 1.5 V DDR3 voltage, the 4 GB module draws minimal power and stays cool inside typical server airflow paths.
