HPE 16 GB DDR4 2400 Registered Module

This HPE 805349-B21 module provides 16 GB of DDR4 memory rated at 2400 MT/s. It uses a 288-pin registered DIMM with a 1Rx4 organisation. The part is intended for server platforms that require registered memory.

Suitable for servers needing registered DDR4 2400

This module fits systems that accept registered DDR4 2400 memory in a 288-pin slot. It is not for workstations or desktops that require unbuffered UDIMMs. Buyers who need different speeds, higher densities per slot, or non-registered memory should look at other modules.

Registered 1Rx4 DDR4 2400 signal

The registered 1Rx4 design determines electrical loading on the memory bus. Verify that the server motherboard and processor support registered DDR4 2400 with this rank configuration before purchase.

Questions about this item

Does the 1Rx4 rank layout restrict the maximum capacity I can reach per channel?

Each module is a single-rank 1Rx4 design, so the channel limit depends on how many ranks your server's memory controller allows per channel.

How much heat does a registered 2400 MT/s module add when the server runs 24/7?

Registered DDR4 2400 modules draw modest power; the onboard register adds slight overhead but total thermal load stays within standard RDIMM limits for continuous operation.

What slot type must the motherboard provide for this 288-pin DDR4 RDIMM?

The module requires a 288-pin DDR4 RDIMM socket that supports registered memory.
