SuperMicro DDR5 4800 ECC RDIMM kit

This 128GB kit contains two 64GB DDR5 4800 registered DIMMs built for SuperMicro servers and workstations. Each module runs at 1.10V with CL40 latency and 2Rx4 organisation. ECC and register buffering protect data integrity in mission-critical workloads.

Installation and common issues

The 288-pin DDR5 RDIMMs install in minutes by seating them in the correct DIMM slots per the system manual. Ensure the motherboard firmware supports DDR5 4800 registered ECC before adding the kit. Mixing ranks or voltages can prevent boot.

Suitable buyers and mismatched needs

IT teams running SuperMicro X13SEM-F or X13SEM-TF platforms that require registered ECC memory at 4800 MT/s will benefit. Builders needing unbuffered UDIMMs, non-ECC modules, or speeds above 4800 should look at other product lines.

Questions about this item

How can I confirm the kit is running at DDR5 4800 with CL40 timings after installation?

Check the memory speed and CAS latency in the server BIOS or a hardware monitoring tool; the modules should report 4800 MT/s and CL40 when operating as specified.

What comes in the package and do I need any extra parts for a SuperMicro X13SEM-F or X13SEM-TF?

The box contains the 128 GB kit as two 64 GB 288-pin DDR5 RDIMMs; no additional components are required for the listed SuperMicro systems.

Should I choose the 2Rx4 registered ECC version or a different rank configuration for my SuperServer?

Select this 2Rx4 registered ECC kit; it matches the memory specification validated for the compatible SuperMicro platforms.
