Compatible Supermicro Server Memory

This 16GB DDR4 ECC unbuffered UDIMM is validated for Supermicro X12 series motherboards including the X12SAE-5, X12SCA-5F and X12STH-F. It targets administrators who need error-correcting memory for stable server or workstation operation without registered DIMM requirements.

Thermals and Power at Standard Speed

Operating at 1.20V, the module draws minimal power and runs without a heat spreader, relying on chassis airflow for cooling. The unbuffered design keeps electrical load low, contributing to quiet operation in typical rack or tower environments.

Behaviour Under Sustained Load

Each module undergoes rigorous stress testing under load to ensure reliability during continuous operation. The 2Rx8 organisation and CL22 latency maintain data integrity across extended workloads, while ECC corrects single-bit errors that can accumulate over time.

Questions about this item

How do I install this 288-pin DDR4 ECC UDIMM in a SuperMicro X12 motherboard, and what step is often missed?

Align the notch on the module with the slot key, press firmly until both side clips click, then verify in BIOS that the 16GB module is detected at 3200MT/s with ECC active.

What maintenance or replacement will this 1.2V 2Rx8 module need over time?

No scheduled maintenance is required; if a memory error occurs, replace the module as a single 16GB unit.

What limit appears first when this CL22 ECC UDIMM runs sustained workloads?

The CAS latency of 22 cycles at 3200MT/s sets the timing floor, so sustained throughput is bounded by that latency.
