64GB DDR5 RDIMM for Servers

This 64GB DDR5 registered DIMM runs at 4800 MT/s with CL40 latency and 1.10V operation. It is built for servers and workstations that require error-correcting memory and registered signal integrity.

Registered ECC with Dual-Rank Layout

The registered buffer reduces electrical load on the memory controller, while on-die ECC corrects single-bit errors to protect data integrity. A 2Rx4 organisation delivers high density within a single 288-pin module.

DDR5 4800 CL40 2Rx4 Registered

This module only works in platforms that support DDR5 RDIMMs with registered signalling and ECC. It will not function in consumer desktop boards, laptops or any system limited to unbuffered UDIMMs.

商品問答

Will the 2Rx4 registered ECC module need any firmware updates or component replacements during its service life?

The module has no heat spreader and no user-serviceable parts; registered ECC DDR5 DIMMs are not field-upgradable and require no scheduled maintenance.

What limit appears first when the 4800 MHz CL40 kit runs sustained workloads?

The CL40 latency and 1.10 V operating point set the timing and voltage envelope; sustained throughput is bounded by the 4800 MT/s data rate and dual-rank organisation.

How much heat and noise does a 64 GB stick produce when the server runs all day?

With no heat spreader and a standard 1.10 V DDR5 voltage, the module relies on chassis airflow; it adds no active cooling and generates no audible noise.
