64GB DDR5 4800 ECC RDIMM for Supermicro

This 64GB DDR5 4800 registered DIMM targets IT teams maintaining Supermicro IoT SuperServer SYS-211SE-31DS, SYS-211SE-31AS and X31SEED-SF platforms. ECC and registered buffering protect data integrity in continuous server workloads. The module operates at 1.1V with CL40 latency.

Registered ECC DDR5 4800 compatibility

The single specification that decides fit is registered ECC DDR5 4800 with a 2Rx4 organisation on a 288-pin interface. Only systems expecting PC5-38400 registered modules will initialise this DIMM correctly. Consumer boards and unbuffered platforms will not post with it.

Tool-free slot insertion, check population rules

Installation is a vertical press into the DDR5 slot until the retention clips engage, typically completed in minutes. The common failure is ignoring the motherboard population sequence for 2Rx4 registered DIMMs, which prevents boot. Verify the qualified vendor list and BIOS revision before seating the module.

Questions about this item

What does the DDR5 4800 PC5-38400 speed rating mean for actual throughput in a Supermicro server?

DDR5-4800 is the data rate; PC5-38400 is the corresponding peak transfer rate designation. In a supported Supermicro system the module will operate at up to 4800 MT/s.

How does the ECC RDIMM registration affect compatibility with the SYS-211SE-31DS motherboard?

The module is a registered ECC RDIMM, which the Supermicro SYS-211SE-31DS and similar X31SEED-SF platforms require for memory error correction and signal integrity.

Will the 288-pin 1.1 V 2Rx4 module fit the memory slots on a Supermicro IoT SuperServer?

Yes — it uses the standard 288-pin DDR5 RDIMM form factor at 1.1 V, matching the DIMM slots on the listed Supermicro IoT SuperServer models.
