Server Memory for Supermicro Systems

This 64GB DDR4 3200 module is built for servers and workstations that require registered ECC memory. It suits administrators upgrading Supermicro platforms where validated compatibility is essential. The single-module design allows precise capacity scaling per slot. Buyers needing non-ECC or unbuffered DIMMs for consumer boards should look elsewhere.

Supermicro Certified 64GB RDIMM

The decisive specification is the Supermicro certification on part number MEM-DR464L-ER32 with Samsung M393A8G40CB4-CWE chips. This validation confirms the module meets the vendor's qualified-vendor-list requirements for supported Supermicro platforms. Without this certification the same capacity and speed may not be accepted by the system firmware.

Sustained Load Stability

Registered buffering and ECC correction maintain data integrity during continuous multi-threaded workloads such as virtualisation or database processing. The 1.20V standard voltage and CL22 latency deliver consistent throughput without exceeding DDR4 power envelopes. Thermal throttling is avoided because the registered design reduces electrical load on the memory controller during extended operation.

Questions about this item

What does the 3200 MT/s rating mean once the module is installed in a server?

The module runs at 3200 MT/s with CL22 latency at 1.2 V, delivering the rated PC4-25600 bandwidth when the platform supports DDR4-3200.

How does the DDR4 RDIMM interface affect maximum capacity per channel?

As a registered 288-pin DDR4 RDIMM, it presents a single electrical load per rank, allowing larger per-channel populations than unbuffered DIMMs.

What physical slot and clearance does this 64 GB stick require?

It needs a standard 288-pin DDR4 RDIMM socket; the dual-rank 2Rx4 Samsung chipset fits the regular DIMM height used in Supermicro platforms.
