Certified Server Memory

This is a 32GB DDR4 3200MHz ECC Registered DIMM built to Supermicro MEM-DR432MD-ER32 specifications using Hynix components. It delivers 32GB of capacity at PC4-25600 speed with CL22 latency and 1.20V operation for compatible server platforms.

System Builders And IT Managers

This module suits administrators expanding memory in qualified Supermicro servers that require registered ECC RDIMMs. It is not for desktop PCs or workstations that accept only unbuffered non-ECC memory, nor for systems limited to lower densities or different form factors.

Registered ECC RDIMM Form Factor

The 288-pin RDIMM design with 2Rx8 organisation and on-board register is the single specification that determines fit; only motherboards wired for registered ECC DDR4 can use this module.
