Overview
Kingston's Server Premier DDR5-6400 family is the 6400 MT/s step above the widely deployed 5600 MT/s server modules. It covers 16 GB single-rank, 32 GB dual-rank and 64 GB dual-rank capacities in a 288-pin ECC Registered DIMM package, with JEDEC timings of 52-52-52 at 1.1 V.
For platform qualification the details that matter are on-die ECC combined with an x80 ECC path across two independent 40-bit sub-channels, 32 internal banks across eight bank groups, hard and soft post-package repair, and I3C/I2C sideband access. At 31.25 mm module height the parts fit standard server DIMM slots, and 6400 MT/s is the native speed of current Granite Rapids and Turin platforms.
Key Benefits
6400 MT/s native matches current Intel and AMD server memory controllers without overclocking. On-die ECC plus x80 sub-channel ECC covers both bit errors and DRAM-internal faults. Post-package repair and I3C sideband reduce field replacement and improve fleet telemetry. Multiple die sources published lets procurement avoid single-vendor allocation risk.
Applications
AI inference nodes and GPU host memory, general-purpose virtualisation hosts, in-memory databases, analytics servers, and any current-generation server where 6400 MT/s is the rated DDR5 speed.
