32GB DDR5 ECC RDIMM kit for Supermicro workstations

This 32GB kit contains two 16GB DDR5 4800 registered DIMMs built for Supermicro SuperWorkstation SYS-531A-I and X13SRA-TF platforms. Each module runs at 1.10V with CL40 latency and 1Rx8 organisation. ECC and register buffering provide the data-integrity required in server and workstation workloads.

Fits 288-pin DDR5 RDIMM slots on validated

The modules install directly into the workstation's registered DIMM sockets without adapters. Registered signalling reduces electrical load on the memory controller, freeing headroom for additional DIMMs if the board supports higher population. No heat spreaders are fitted, so clearance inside dense chassis is maximised.

Two matched 16GB modules enable dual-channel

The paired kit ensures identical timing, voltage and rank configuration across both channels. Samsung, Micron or Hynix major-OEM chips are used throughout. Rigorous stress testing under load is performed before shipment to confirm stability in mission-critical environments.

Questions about this item

Will the CL40 latency limit throughput when the 2 x 16 GB DDR5 4800 kit runs sustained workloads?

CL40 is the rated CAS latency at 4800 MT/s; sustained throughput is governed by the DDR5 4800 transfer rate and the registered buffer on each module.

How much noise and heat will the 2 x 16 GB registered ECC kit add during all-day operation?

The modules have no heat spreader and draw 1.10 V; they add no fan noise and only the heat normal for 32 GB of registered DDR5 under load.

Which motherboard slot and system firmware are required for the 288-pin RDIMM pair to function?

A Supermicro motherboard with DDR5 RDIMM slots and BIOS that supports 4800 MT/s registered ECC is required; the kit is validated for the SYS-531A-I workstation.
