Capacity and Purpose

This 64 GB kit provides two 32 GB DDR4 3200 ECC UDIMM modules for Supermicro SuperWorkstation SYS-530A-IL and Super X12SAE-5 systems. It targets administrators who need error-correcting memory to protect data integrity in professional workloads. The unbuffered design suits boards that do not accept registered DIMMs.

Build Integration

Each module runs at 1.2 V with CL22 latency and a 2Rx8 organisation across 288 pins. The kit plugs directly into the workstation's UDIMM slots without requiring registered memory support. No heat spreader is fitted, so airflow across the PCB must be maintained by the chassis fans. Buyers whose boards demand registered DIMMs cannot use this kit.

Package Contents

The box contains only the two memory modules; no additional cables, brackets or software utilities are included. Installation follows the motherboard manual's standard DIMM population rules. The lifetime replacement warranty is handled by the manufacturer and is not a physical item in the package.

Questions about this item

Does the CL22 latency limit throughput during long workloads?

The modules run at DDR4 3200 with CL22 timing; latency is fixed by the JEDEC profile and does not change under sustained load.

How much heat do the modules produce when running continuously at 1.2 V?

The kit operates at 1.20 V without heat spreaders; power draw stays within standard DDR4 3200 unbuffered limits for all-day operation.

Must the motherboard support 2Rx8 ECC unbuffered DIMMs for this kit to work?

Yes — the 288-pin UDIMMs are 2Rx8 ECC unbuffered and require a board that accepts that exact configuration, such as the Supermicro X12SAE-5.
