256GB DDR5 ECC RDIMM kit

This 256GB kit contains eight 32GB DDR5 4800 registered DIMMs with ECC and a CL40 latency. It is built for Supermicro servers such as the SYS-211E-FRN2T, SYS-211E-FRDN2T, X13SEM-F and X13SEM-TF that require registered error-correcting memory.

Installation and common issues

The 288-pin modules install in standard DDR5 RDIMM slots and operate at 1.1V. Populate all eight slots identically to maintain matched ranks and avoid mixed-rank errors; the motherboard manual shows the correct population order for eight DIMMs.

Capacity headroom

Eight ranks of 1Rx4 chips deliver 256GB total, suited for virtualisation hosts, large databases and memory-heavy compute nodes. Workloads that exceed this capacity or need faster than 4800 MT/s will require a platform with higher-density modules or greater memory bandwidth.

Questions about this item

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

Check the BIOS or a tool such as CPU-Z; the memory should report 4800 MT/s, PC5-38400 bandwidth and CL40 timings at 1.10 V.

What exactly ships in the box and is anything else required?

The package contains eight 32 GB 288-pin DDR5 RDIMM modules for a total of 256 GB; no extra parts are needed for a compatible Supermicro system.

Which capacity version should I choose for a Supermicro SYS-211E-FRN2T?

This 256 GB kit (8 × 32 GB, 1Rx4, ECC registered) matches the supported configuration for the SYS-211E-FRN2T and similar X13SEM platforms.
