SuperMicro Workstation Memory

This 32GB DDR4 3200 ECC UDIMM module is built for the SuperMicro SuperWorkstation SYS-530A-IL and X12SAE-5 motherboard. It targets IT professionals and system builders who need validated, error-correcting memory for mission-critical workloads. The single-rank 2Rx8 design fits a standard 288-pin slot and operates at 1.2V. Buyers who need registered DIMMs or higher-frequency kits should look elsewhere.

Thermals and Power Draw

Running at 1.20V with CL22 latency, the module draws minimal power and generates low heat during typical server and workstation tasks. No heat spreader is fitted, so airflow across the PCB handles cooling in a properly ventilated chassis. The unbuffered design keeps electrical load light on the memory controller. Audible noise is not a factor with this passive component.

What the Package Changes

The box contains one 32GB DDR4 3200 (PC4-25600) ECC UDIMM tested for the listed SuperMicro platforms. Installing it adds capacity and error correction without requiring software drivers or configuration utilities. Compatibility validation by the manufacturer reduces the risk of POST failures or instability. No additional cables, brackets or licensing keys are included.

Questions about this item

How do I install the 288-pin DDR4 ECC UDIMM into the SuperMicro SYS-530A-IL, and what step is often missed?

Align the notch on the module with the slot key, press firmly until both retention clips click shut, then verify in BIOS that the 32GB appears at 3200 MT/s with ECC active.

What maintenance or replacement will this 32GB 2Rx8 module need over its service life?

No scheduled maintenance is required; if a memory error occurs, the ECC function corrects single-bit faults, but the module itself must be replaced if multi-bit failures appear.

What limit appears first when this CL22 1.2V kit runs sustained workloads on the X12SAE-5 motherboard?

The CAS latency of 22 cycles at 3200 MT/s sets the timing floor; thermal throttling is unlikely without a heat spreader, so latency remains the primary constraint.
