16 GB DDR4 ECC UDIMM for servers

This 16 GB DDR4 2666 MHz ECC UDIMM module is built for servers and workstations that require error-correcting unbuffered memory. It operates at the standard 1.20 V DDR4 voltage with CL19 latency and a 2Rx8 rank configuration. The 288-pin DIMM uses major-brand chips and serves as a direct replacement for Hynix HMA82GU7CJR8N-VK and HMA82GU8CJR8N-VK modules.

Compatibility checklist before purchase

Verify that your motherboard supports DDR4 ECC UDIMM modules at 2666 MHz and accepts 16 GB single-rank or dual-rank sticks. Confirm the system requires unbuffered ECC rather than registered ECC, as the two types are not interchangeable. Check the maximum memory capacity per slot and the total number of available 288-pin slots in your chassis. Ensure the BIOS is updated to recognise 2Rx8 density modules.

Ideal for ECC workstation upgrades

Suits administrators upgrading compatible Dell, HP, Lenovo or Supermicro platforms that specify ECC UDIMM memory. Not suited for consumer desktop boards that lack ECC support or for servers requiring registered RDIMM or LRDIMM modules. Buyers needing higher densities per module or faster speeds should look at other specifications.
