Overview
SMART Modular's DuraMemory DDR5 RDIMM line is a JEDEC-standard 288-pin registered ECC server module family spanning 16GB to 256GB per module at DDR5-4800 and 5600 MT/s. Each module carries its own PMIC and register clock driver on the DIMM, as DDR5 requires.
Because the register isolates the memory controller from the DRAM load, RDIMMs let a server populate more modules per channel while holding signal integrity, which is why they are standard in enterprise servers and AI/HPC nodes. DuraMemory modules are offered in commercial (0 °C to +70 °C) and, on selected SKUs, industrial (-40 °C to +85 °C) temperature grades.
