512GB DDR5 ECC RDIMM kit

This kit supplies 512GB of DDR5 ECC registered memory across sixteen 32GB modules. It is built for Supermicro FatTwin SuperServer platforms such as the SYS-F521E3-RTB, SYS-F511E2-RT and X13SEFR-A. The registered design and error correction suit enterprise workloads that demand data integrity. Buyers needing non-ECC or unbuffered DIMMs for consumer boards should look elsewhere.

Sustained throughput at 4800 MT/s

Rated at DDR5 4800 (PC5-38400) with CL40 latency, the modules maintain their rated speed under continuous server loads. The 1Rx4 organisation and 1.10V operation keep signal integrity stable during long compute runs. Systems that require higher frequencies or lower latencies will not reach those targets with this kit.

Thermals and power in normal use

Each module runs at 1.10V without a heat spreader, relying on chassis airflow for cooling. The low voltage and registered buffering help limit power draw per DIMM during typical operation. Deployments in enclosures with restricted airflow may need additional cooling to sustain rated performance.

Questions about this item

How much heat and power do the 1.10V 1Rx4 RDIMMs generate when the server runs continuously?

The kit operates at 1.10V with a 1Rx4 organisation and no heat spreader, so each 32GB module draws minimal power and relies on the chassis airflow for cooling during all-day workloads.

What motherboard slots and firmware must my Supermicro system already provide for this 16-module kit to be recognised?

You need 16 free 288-pin DDR5 RDIMM slots and a BIOS that supports DDR5 4800 registered ECC memory with a 1Rx4 rank configuration on the target Supermicro platform.

Can I mix these CL40 1Rx4 RDIMMs with other DDR5 registered ECC modules already installed in the same server?

Mixing is possible only if the existing modules are also DDR5 4800 registered ECC RDIMMs with matching 1Rx4 rank and CL40 timing; otherwise the memory controller will down-clock or disable the mismatched DIMMs.
