32GB DDR5 ECC RDIMM for Supermicro Workstations

This registered DDR5 module delivers 32GB of error-correcting memory at 4800 MT/s with CL40 latency. It operates at 1.1V using a 1Rx4 organisation on a 288-pin form factor. The part is validated for the Supermicro SuperWorkstation SYS-531A-I and Super X13SRA-TF platforms.

Upgrading from lower-capacity or non-ECC DDR5

Replacing unbuffered or smaller registered DIMMs with this 32GB stick adds capacity and data-integrity protection for workloads that exceed standard desktop limits. The jump is worthwhile when the motherboard supports registered memory and the application benefits from ECC correction.

Registered DDR5 requires compatible server chipset

The RDIMM register adds one cycle of command buffering, so the memory controller must explicitly support registered operation. Consumer chipsets that accept only unbuffered DIMMs will not post with this module installed.

Questions about this item

Does the 288-pin DDR5 RDIMM fit the Supermicro SYS-531A-I workstation?

Yes, the module is built to the 288-pin DDR5 RDIMM form factor specified for the Supermicro SYS-531A-I SuperWorkstation.

Do I need to populate slots in a specific order for the 1Rx4 registered module?

Install the RDIMM in the slot sequence shown in the Supermicro SYS-531A-I manual; registered modules require correct channel population for the memory controller to initialise.

Will the Samsung, Micron or Hynix DRAM chips need active cooling later?

The module ships without a heat spreader; ensure chassis airflow meets the Supermicro SYS-531A-I thermal guidelines so the bare DRAM stays within operating temperature.
