Server Memory Capacity

This 64 GB DDR4 RDIMM adds a single high-density module to compatible Supermicro platforms. It targets administrators who need registered ECC memory for virtualization hosts or database servers.

Sustained Load Behaviour

Registered buffering and ECC correction keep data integrity intact during continuous multi-threaded workloads. The module runs at the standard 1.20 V, so thermal output remains predictable inside dense chassis.

DDR4 Interface Limits

The PC4-25600 rating caps peak bandwidth at the DDR4 3200 specification. Systems that only support lower speeds will clock the module down automatically. Builders who need more capacity per slot must verify motherboard qualification lists before ordering.

Questions about this item

How much power does the 1.20 V DDR4 3200 module draw when the server runs continuously?

It operates at the standard DDR4 voltage of 1.20 V; actual power draw depends on the platform's memory controller and workload, so consult your system documentation for precise figures.

What must the motherboard provide for this 288-pin RDIMM to function?

A DDR4 RDIMM slot that supports 64 GB 2Rx4 modules at 3200 MHz with ECC registered operation.

Can this CL22 3200 MHz stick run in a system that currently uses slower DDR4 RDIMMs?

The module will down-clock to the lowest common speed supported by the memory controller; verify your platform's qualified-vendor list for mixed-speed population rules.
