256 GB DDR5 4800 RDIMM for Servers

This single 256 GB DDR5 4800 CL40 registered DIMM is built for enterprise servers and workstations that require ECC protection. It operates at 1.1 V and uses 288-pin DDR5 form factor. The module targets IT departments upgrading memory capacity in compatible DDR5 platforms.

Top-tier DRAM chips and lifetime replacement

Samsung, Micron or Hynix DRAM components are selected and each stick is tested before shipping. The registered buffer and on-die ECC reduce signal loading and correct single-bit errors, improving data integrity under sustained workloads. A lifetime replacement warranty backs the module.

Suits DDR5 servers needing maximum density per slot

Ideal for database hosts, virtualization clusters or AI training nodes that accept 256 GB RDIMMs. Not suited for consumer desktops, laptops or any system limited to unbuffered UDIMMs or lower-density registered modules. Buyers who need registered memory below 256 GB per slot should look at smaller-capacity RDIMMs.

Questions about this item

Will the Samsung, Micron or Hynix DRAM chips used in this 256 GB module require any scheduled replacement?

The module uses major OEM Samsung, Micron and Hynix DRAM chips and is covered by a lifetime replacement warranty; no scheduled chip replacement is needed.

What is the first limit reached when this DDR5 4800 CL40 RDIMM runs sustained workloads?

The module operates at DDR5 4800 (PC5-38400) with CL40 latency at 1.10 V; sustained throughput is capped by that rated speed and latency.

How much heat and power does this 1.1 V 288-pin registered ECC DIMM produce when running all day?

At 1.1 V the module draws minimal power for DDR5, and registered ECC operation keeps signal integrity high without extra heat beyond normal server DIMM levels.
