16GB DDR5 4800 ECC RDIMM for HP servers

This 16GB DDR5 4800 ECC registered DIMM is built for HP server and workstation platforms that require the N20161-001 part number. It targets administrators who need to add dependable capacity to production systems.

Sustained operation at 4800 MT/s

The module runs at the standard DDR5 voltage of 1.10V while maintaining CL40 timings across continuous workloads. ECC and registered signalling protect data integrity during long compute cycles.

Verify your platform accepts 288-pin DDR5 RDIMMs

Confirm the motherboard supports registered ECC DDR5 at this speed and that the 288-pin form factor matches the memory slots. Check the system documentation for the N20161-001 qualification before ordering.

Questions about this item

How much power does the 1.1V DDR5 4800 RDIMM draw during continuous server workloads?

The module operates at the standard DDR5 voltage of 1.1V, which helps limit heat output and power draw during all-day operation in compatible server platforms.

What motherboard slot and memory-channel configuration are required for this 288-pin RDIMM?

It requires a DDR5 RDIMM slot with 288 pins and a platform that supports registered ECC memory at 4800 MT/s; the system must also accept 1Rx8 organisation.

Can I mix this 1Rx8 CL40 module with other DDR5 RDIMMs of different rank or speed in the same server?

Mixing ranks or speeds is not recommended; the motherboard will typically down-clock all modules to the slowest common speed and may require identical rank-per-channel population for stability.
