Supermicro Certified 8GB DDR4 ECC UDIMM

This A-Tech module is an 8GB DDR4 2133MHz ECC unbuffered UDIMM built with Samsung chips and validated for Supermicro systems. It suits administrators upgrading or repairing Supermicro servers and workstations that require registered ECC memory at standard voltage. Buyers who need registered DIMMs, higher capacities per slot, or speeds beyond 2133MHz cannot use this module.

Samsung M391A1G43DB0-CPB chipset

The Samsung M391A1G43DB0-CPB chipset provides the 2Rx8 dual-rank organisation at CL15 latency and 1.20V operation. Supermicro certification means the module has passed the vendor qualification suite for the listed part number MEM-DR480L-SL01-EU21. No extra software, heat spreaders, or accessories are included; the change is purely the qualified memory itself.

288-pin UDIMM installation and compatibility checks

Installation follows the standard 288-pin UDIMM procedure: align the key notch, press until the latches click, and verify detection in BIOS. The most common issue is purchasing unbuffered ECC for a platform that requires registered ECC, or mixing ranks in a way the motherboard firmware does not support. Always confirm the exact supported memory list for your Supermicro model before ordering.
