128GB DDR5 6400 ECC RDIMM Module

This 128GB DDR5 6400 registered DIMM delivers error-correcting memory for servers and workstations that require data integrity. The module operates at 1.10V with CAS latency 32 and uses a 288-pin form factor. It is built as a direct replacement for specific Hynix part numbers.

Suits registered-memory platforms needing maximum

Buyers whose systems accept only unbuffered UDIMMs or non-ECC modules cannot use this product. Platforms limited to lower DDR5 speeds or smaller maximum module sizes should verify compatibility before purchase. The single-module design also means dual-channel bandwidth requires a second identical stick.

128GB capacity with DDR5 6400 headroom

The 128GB density handles large virtualisation workloads, in-memory databases and heavy multi-user applications comfortably. Workloads that exceed per-module capacity limits or demand higher frequencies than 6400 will require additional modules or a platform supporting faster memory.

商品問答

Does my motherboard need DDR5 RDIMM slots and ECC support to run this 128GB DDR5 6400 2Rx4 module?

Yes, the module requires a 288-pin DDR5 RDIMM slot and a platform that enables ECC registered memory at 1.10V.

Can I install this 128GB DDR5 6400 2Rx4 ECC RDIMM alongside existing DDR5 RDIMMs of different capacities in my server?

Mixed-capacity DDR5 RDIMMs can work if the motherboard and CPU support the total population and the memory controller trains all ranks at 6400 MT/s with CL32.

How do I verify this 128GB DDR5 6400 2Rx4 ECC RDIMM is operating at its rated speed and ECC function after installation?

Check the BIOS memory information or OS tools such as dmidecode to confirm 6400 MT/s, CL32, 1.10V, registered ECC mode and 2Rx4 organisation.
