Server-grade ECC RDIMM for workstations

This 16GB DDR3 1600 module delivers registered ECC memory for servers, workstations, NAS devices and routers. It replaces specific HP part numbers including 672612081 and 684031001 with JEDEC-standard specifications. The module is not compatible with standard desktop computers or unbuffered memory configurations.

Sustained-load stability with error correction

Registered buffering reduces electrical load on the memory controller during continuous operation, while ECC detects and corrects single-bit errors in real time. CL11 latency at 1.5V provides reliable throughput for multi-user workloads, virtualization and long-running compute tasks without the soft-error accumulation seen in non-ECC alternatives.

Verify registered DIMM support before ordering

Your system must explicitly support DDR3 240-pin ECC registered RDIMMs; consumer motherboards and laptops will not accept this module. Check the vendor’s qualified-vendor list for 2Rx4 rank compatibility and confirm the platform requires 1.5V registered memory rather than unbuffered or low-voltage variants.

Perguntas sobre este artigo

Does the 1.5V DDR3 1600 module add noticeable heat or power draw when the server runs continuously?

At 1.5V and CL11 the registered DIMM draws standard DDR3 power; registered buffering adds minimal overhead so thermals stay comparable to other PC3-12800 ECC RDIMMs.

What must the system already provide for this 240-pin 2Rx4 registered ECC stick to function?

A workstation, server, NAS or router motherboard with DDR3 RDIMM slots that accept 2Rx4 registered ECC modules at PC3-12800 speed.

Can I keep older unbuffered DDR3 DIMMs installed alongside this registered 16GB module?

No — the manufacturer states registered memory cannot be mixed with unbuffered memory; all slots must use registered ECC DIMMs.
