Samsung M321R8GA0EB2-CCP 64G DDR5 6400 RDIMM
The Samsung M321R8GA0EB2-CCP is a 64GB DDR5 module delivered on an unbuffered DIMM (UDIMM) form factor, positioned for workstation, content-creation, AI development, and high-performance computing (HPC) builds rather than multi-socket registered-memory servers. It runs at a 4800 MT/s data rate (PC5-38400 speed grade, ~38.4 GB/s bandwidth per module) at a low 1.1V operating voltage, and carries On-Die ECC for improved data integrity at the DRAM level. Note for procurement: verify your platform’s validated memory list before ordering, as the source listing shows a conflicting title reference (6400 RDIMM) — the specification table below should be treated as authoritative, and DDR5 modules cannot be mixed with DDR4 or registered RDIMMs on most boards.

Good to know
- As a UDIMM, this module targets desktop/workstation-class platforms; unbuffered and registered (RDIMM) DDR5 memory must not be mixed on the same system, so confirm your board’s supported DIMM type before purchase.
- Within Samsung’s DDR5 portfolio, the 2Rx8 dual-rank configuration at 64GB offers a common capacity-per-module point for workstation memory population; consult your motherboard manual for recommended channel population to maximize multi-channel bandwidth.
- Bulk buyers should request current lot and revision details at quotation stage, and verify the data rate against the source listing title discrepancy (4800 MT/s per the spec table) before committing to large quantities.
For tray and reel pricing, current stock by part number and date code, and volume discounts on bulk orders, request a bulk quotation.
