128GB DDR4 LRDIMM Server Memory

This 128GB DDR4 LRDIMM module delivers registered ECC memory for compatible Supermicro UP and DP server platforms. It operates at DDR4 3200 with a CAS latency of CL22 and a voltage of 1.20V. The 2Rx4 rank configuration and 288-pin form factor suit high-density memory slots in validated systems.

Suited for memory-intensive server workloads

The registered ECC design supports data integrity in virtualisation, database and compute clusters running on listed SSG-520P, SSG-540P, SSG-620P and SSG-640P models. Builders needing unbuffered UDIMMs, standard RDIMMs, lower capacities or different DDR generations should select alternative modules that match their platform requirements.

Steady throughput under sustained load

Registered buffering and ECC correction maintain signal integrity during continuous read and write cycles across all 128GB. The CL22 timing at 3200 MT/s provides consistent latency for long-running tasks without the error accumulation seen in non-ECC memory under heavy utilisation.

Perguntas sobre este artigo

What motherboard socket and chipset must I already have for this 128GB DDR4 3200 LRDIMM to function?

This module requires a server platform with 288-pin DDR4 slots that support LRDIMM, ECC, registered operation, 1.20V voltage, and 2Rx4 rank configuration at 3200 MT/s.

Can I mix this 2Rx4 LRDIMM with existing 1Rx4 or 2Rx8 RDIMMs in the same Supermicro SSG-640P-E1CR24H?

Mixing LRDIMMs with RDIMMs or different rank architectures in the same system is not supported; all populated slots should use identical LRDIMM specifications for stable operation.

How do I verify the module is running at DDR4 3200 with CL22 latency and ECC active after installation?

Enter the system BIOS or UEFI and confirm the memory speed reads 3200 MT/s, CAS latency shows CL22, voltage reports 1.20V, and ECC status is enabled for the 128GB capacity.
