HP 16GB DDR3 1600 Registered DIMM

This HP 684031-001 module provides 16GB of DDR3 1600 registered ECC memory. It uses a 240-pin DIMM form factor and operates at 1.50V with a 2Rx4 rank configuration. It is designed for specific HP server platforms requiring registered signal processing. ||

Suits HP Gen8 servers needing ECC registered RAM

This memory fits the listed HP ProLiant BL460c Gen8 and ARST OEM C3500, C5500, L3500, L7500 base servers. It is not for desktop motherboards or workstations that require unbuffered non-ECC modules. Buyers needing unregistered memory or a different DDR generation should look elsewhere. ||

Registered ECC with 2Rx4 organisation

The module implements registered signal processing and ECC error checking in a dual-rank x4 layout. This specific electrical organisation is the decisive factor for compatibility with the supported HP server memory controllers. Only systems qualified for this registered 2Rx4 PC3-12800R configuration will accept it.

Questions about this item

How do I install this 240-pin DDR3 registered DIMM and which step is often missed?

Align the notch on the module with the slot key, press firmly until both side clips lock, and verify the server BIOS recognises the full 16 GB capacity at 1600 MHz.

What maintenance or replacement will this 16 GB registered ECC module need over time?

No routine maintenance is required; if a memory error occurs the module itself is replaced, and compatibility is limited to the listed HP server platforms.

What limit appears first when this DDR3 1600 registered memory runs under sustained load?

The 1.50 V operating voltage and DDR3 1600 speed define the thermal and bandwidth ceiling during continuous server workloads.
