64GB DDR4 3200 ECC LRDIMM Module

This 64GB DDR4 3200 ECC LRDIMM module is built for servers and workstations that need high-capacity, error-correcting memory. It replaces the Samsung M386A8K40DM2-CWE part number in compatible systems. The load-reduced design helps reduce electrical load on the memory bus. Buyers who need non-ECC or unbuffered DIMMs should look elsewhere.

Load-Reduced ECC Architecture

The load-reduced ECC architecture buffers both data and address signals to lessen the electrical load on the memory controller. This allows higher module densities such as this 64GB 4Rx4 configuration to operate at 3200 MT/s. The module uses Samsung chipsets and runs at the standard 1.20V DDR4 voltage. Systems without LRDIMM support cannot use this module.

DDR4 288-Pin Interface Limits

The DDR4 288-pin interface used here is keyed differently from other DDR generations and will not fit UDIMM or RDIMM slots. Maximum speed is limited to the DDR4 3200 JEDEC standard supported by the platform. Mixed populations with RDIMMs may force lower speeds or prevent boot. Verify your system's qualified vendor list before purchase.

Perguntas sobre este artigo

Does the 4Rx4 rank configuration on this 64GB module require any special maintenance or replacement schedule?

No special maintenance is required for the 4Rx4 organisation; the module is a solid-state component with no moving parts and is designed to remain in service for the life of the server.

What limit appears first when the 3200 MT/s DDR4 LRDIMM runs sustained workloads?

The CL22 latency at 3200 MT/s sets the timing boundary; sustained throughput is constrained by the DDR4-3200 interface rather than the 1.20 V supply.

How much heat and noise does the 1.20 V ECC LRDIMM produce during all-day operation?

The 1.20 V DDR4 module generates minimal heat and is completely silent; Load Reduced buffering lowers electrical load on the memory bus without adding acoustic noise.
