SuperMicro DDR5 4800 ECC RDIMM Kit

This 256 GB kit contains eight 32 GB registered DDR5 modules rated at 4800 MT/s with CL40 latency and 1.1 V operation. It is built for SuperMicro IoT SuperServer systems such as the SYS-211SE-31DS, SYS-211SE-31AS and X31SEED-SF motherboards. The modules use major-brand DRAM and include on-die ECC for data integrity in server workloads.

Registered ECC memory for compatible SuperMicro

The kit suits administrators upgrading the listed SuperMicro platforms where registered ECC RDIMMs are required. It will not work in systems that accept only unbuffered UDIMMs, lack DDR5 slots, or cannot address 32 GB per module. Buyers needing non-ECC memory or lower-density modules for consumer boards should look elsewhere.

256 GB total capacity across eight 32 GB RDIMMs

The 256 GB aggregate capacity is the primary specification that determines whether this kit fits the target server's maximum memory limit and slot count. Each module is a single-rank 1Rx4 288-pin DDR5 RDIMM running at PC5-38400 speed. Verify the platform's supported capacity per slot and total population rules before purchase.

Questions about this item

Does the CL40 latency become a bottleneck during sustained server workloads?

CL40 is the rated CAS latency at DDR5 4800; under continuous load the memory controller operates at this timing, so the limit is the module's specified latency itself.

How much heat do eight 1.10 V RDIMMs generate when running all day?

Each module runs at 1.10 V without a heat spreader; total power draw scales with the eight-module kit, so airflow across the 288-pin slots must handle the combined thermal output.

Which SuperMicro systems must I already own for this 256 GB kit to work?

The kit is validated for SuperMicro IoT SuperServer SYS-211SE-31DS, SYS-211SE-31AS and X31SEED-SF motherboards; one of these platforms is required for compatibility.
