16GB DDR4 2400 ECC RDIMM

This 16GB DDR4 2400 registered DIMM adds error-correcting capacity to compatible HP servers. It operates at 1.20V with CL15 latency and a 1Rx4 organisation. The module uses major-brand chips and matches the 855506-091 specification for direct replacement.

Sustained load behaviour

Registered buffering and ECC maintain data integrity during continuous multi-threaded workloads such as virtualisation or database hosting. The 2400 MT/s rate delivers steady bandwidth without the voltage spikes seen in higher-speed unbuffered kits. Thermal load remains consistent at the rated 1.20V.

Upgrade context

This module replaces lower-capacity DDR4 RDIMMs in systems that already support PC4-19200 registered memory. The jump is worth it when current DIMM slots limit virtual-machine density or cause paging under load. It is not for platforms that require unbuffered UDIMMs or a different DDR generation.

Questions about this item

How much power does the 16GB DDR4-2400 RDIMM draw at its rated 1.20V during sustained server workloads?

The module operates at 1.20V, the standard DDR4 voltage, so power draw stays within the JEDEC envelope for registered DIMMs of this density and speed.

What motherboard feature must my system provide to use this registered ECC RDIMM?

The board must support DDR4 registered ECC memory and have an available 288-pin RDIMM slot; unbuffered or non-ECC platforms will not work.

Will this PC4-19200 CL15 module run reliably at 2400 MHz if I keep older DDR4 DIMMs in the other channels?

Yes — the SPD is programmed for DDR4-2400 CL15, and the memory controller will negotiate a common speed across all populated slots.
