MTC20F2085S1RC64BH1

The Micron MTC20F2085S1RC64BH1 is a 32GB DDR5 registered DIMM (RDIMM) in a 288-pin x80 bus configuration with on-module ECC and dual-rank (DR) organisation. It runs at 6400 MT/s (speed 3200MHz clock) at CAS latency CL = 52 with a 1.1 VOLTS I/O supply, and is rated for a 0C to +95C operating temperature. The module is built from 2Gb x8 components — 20 in total — and the current data-sheet is the 32GB Die Revision H document.
