32GB DDR5-4800 ECC Registered DIMM

This 32GB DDR5-4800 ECC RDIMM is built for server and workstation platforms that require registered, error-correcting memory. It runs at 4800 MT/s with a CAS latency of 40 and operates at the standard 1.10V. The module uses a 1Rx4 organisation with Micron DRAM ICs and fits a 288-pin DDR5 slot.

Who this suits and who should look elsewhere

This module suits administrators upgrading or repairing systems that specifically call for a DDR5-4800 ECC RDIMM in a 1Rx4 configuration. It is not for desktop PCs that only accept unbuffered UDIMMs, nor for laptops or small-form-factor devices that use SO-DIMMs. Buyers who need a different capacity, a different speed grade, or a heat-spreader-equipped variant should look at other parts.

The deciding specification

The single specification that determines fit is the registered ECC RDIMM form factor combined with the DDR5-4800 1Rx4 layout; only motherboards with a DDR5 registered DIMM slot and a memory controller that supports this exact rank and speed will accept it.

Questions about this item

How much power does the 1.10 V DDR5 module draw when the server runs continuously?

The module operates at the standard DDR5 voltage of 1.10 V, keeping power draw low during all-day workloads.

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

You need a DDR5-compatible server board with a 288-pin RDIMM slot that supports registered ECC memory.

Will this 4800 MHz ECC RDIMM downclock reliably in a system that only supports lower DDR5 speeds?

Yes, the DDR5-4800 module will automatically run at the highest speed the platform allows while maintaining ECC and registered operation.
