256 GB DDR5 ECC RDIMM kit

This 256 GB kit contains four 64 GB DDR5 4800 registered ECC modules built for SuperMicro X13SEI-F and X13SEI-TF motherboards. It targets administrators upgrading server or workstation memory capacity with validated modules.

Registered DDR5 4800 with CL40 latency

The decisive specification is the registered DDR5 4800 speed combined with CL40 CAS latency and 1.1 V operation, which must match the platform memory controller requirements for stable operation.

Four-module installation in correct slots

Install all four 288-pin RDIMMs in the motherboard's designated memory channels following the manual's population order; the most common issue is mixing ranks or leaving a channel unbalanced, which prevents the system from posting.

Questions about this item

What does the CL40 latency mean for real-world server workloads?

CL40 is the CAS latency at DDR5 4800; lower latency improves response time for database and virtualization tasks, though registered ECC modules prioritize stability over raw speed.

How does the PC5-38400 rating limit usable bandwidth?

PC5-38400 indicates a peak transfer rate of 38,400 MT/s per module; the registered buffer and ECC overhead reduce sustained throughput slightly below that ceiling.

Will the 288-pin RDIMMs fit the SuperMicro X13SEI-F and X13SEI-TF motherboards?

Yes, the kit is validated for those boards; each 64 GB module uses the standard 288-pin DDR5 RDIMM form factor and 1.10 V operation required by the platform.
