16 GB DDR5 RDIMM for servers

This HPE 16 GB registered DDR5 module runs at 4800 MT/s with CL40 timings and 1.10 V operation. The 288-pin RDIMM form factor and single-rank 1Rx8 organisation target enterprise platforms that require registered memory with Smart Memory features.

Suited for registered DDR5 slots only

Systems that accept registered DDR5 RDIMMs at 4800 MT/s can use this kit; builds needing unbuffered UDIMM modules, a different speed grade, or higher capacities per DIMM should select an alternative part.

Registered DDR5 RDIMM with CL40 latency

The registered buffer and CL40 CAS latency define compatibility with qualified HPE server platforms; verify that your system supports registered DDR5 at this timing before purchase.

Perguntas sobre este artigo

What power draw and heat output should I expect from this 1.10V DDR5 4800 module running continuously?

The module operates at 1.10V, the standard voltage for DDR5 4800, keeping power draw and heat low enough for dense server configurations with sustained workloads.

Does my server need a 288-pin DDR5 RDIMM slot and registered-memory support to use this P43322-K21 kit?

Yes, the module is a 288-pin DDR5 RDIMM with registered buffering, so the motherboard must provide DDR5 RDIMM slots and a memory controller that supports registered DIMMs.

Can this 1Rx8 CL40 module be mixed with other DDR5 RDIMMs of different ranks or speeds already in the system?

Mixing is possible if all modules are DDR5 RDIMMs, but the system will run at the lowest common speed and timings; matching rank and CL40 timing avoids down-clocking.
