Server memory upgrade

This 8GB DDR3 1866 ECC RDIMM module is built for HP server and workstation platforms that require registered memory with error correction. It replaces part numbers 731761-B211, 731761-S21, 731657-581, 731761-B21, 731657-081, E2Q94AA and 735303-001. The single-rank 1Rx4 layout uses major-brand chips on a 240-pin DIMM. Systems needing unbuffered DIMMs or non-ECC memory cannot use this module.

Thermals and power draw

The module operates at the standard DDR3 voltage of 1.50V with a CL13 latency rating. Registered buffering reduces the electrical load on the memory controller, which helps keep power draw predictable in multi-DIMM configurations. Passive cooling is sufficient for typical server airflow; no active cooling is required on the module itself.

Sustained load behaviour

ECC detection and correction maintain data integrity during continuous workloads such as virtualisation, database serving or compute clusters. Registered signalling preserves signal quality across fully populated channels, preventing the timing degradation that can appear under prolonged stress. Verify your platform’s qualified-vendor list before installation to ensure full compatibility.

Questions sur cet article

How do I install this 240-pin DDR3 RDIMM in my server?

Align the notch on the module with the key in the DDR3 slot, press down firmly until the retention clips click into place, and ensure the registered module is seated fully before powering on.

What maintenance or replacement will this ECC registered memory need over time?

ECC RDIMMs have no scheduled maintenance; they are replaced only if a memory test reports uncorrectable errors or the server fails to recognise the module.

At what point does the CL13 latency become the limiting factor during sustained workloads?

The CAS 13 timing sets the minimum access delay, so under continuous heavy load the memory controller waits for each CL13 cycle before issuing the next command.
