Overview

Dual-rank 32GB DDR5 is a common building block for 4800 MT/s servers, and this Kingston Server Premier module is one build of it. The KSM48R40BD8KMM-32HMR pairs SK hynix M-die DRAM with a Rambus register clock driver and a Richtek PMIC.

Specs in brief: 32GB, DDR5-4800 (PC5-4800), 40-39-39 timings, 1.1V, dual rank 2Rx8, organized as 4G x 80-bit (EC8), ECC plus on-die ECC, 288 pins, 31.25 mm high and rated from 0 to 95 C. Because Server Premier follows JEDEC specifications, it fits servers from many vendors that take standard DDR5 RDIMMs.

Two replacement part numbers apply: KSM48R40BD8-32HA and KSM48R40BD8-32MD. Let us know if either is acceptable when this exact build is hard to find.

New and Refurbished modules include a choice of 1 year or 3 years of warranty, and Used modules include 90 days.
