Samsung M321R4GA0PB2-CCP 32G DDR5 6400 RDIMM
This module is listed as a Samsung 32GB DDR5 memory module, with the source specification sheet describing it as a DDR5 UDIMM operating at 4800 MT/s. It suits buyers building or maintaining workstations, desktops, and content creation systems rather than registered-memory servers — note the product name carries an RDIMM/6400 designation while the source table specifies UDIMM form factor and 4800 MT/s, so confirm the exact part revision with our sales team before ordering. DDR5 modules are not backward compatible with DDR4 platforms, and mixing generations on one board is not supported.

Good to know
- As a UDIMM, this module targets unbuffered desktop/workstation platforms and will not fit registered-DIMM server boards; check your motherboard’s qualified vendor list (QVL) for DDR5 UDIMM support before ordering.
- Within Samsung’s DDR5 line, this part uses a dual-rank 2Rx8 configuration, which can help capacity-per-channel in consumer and workstation boards that support only two DIMMs per system.
- Because the listing shows conflicting data rate and buffered/unbuffered designations between the product name and the spec table, request the exact module datasheet or physical label confirmation from our sales team prior to shipment.
For tray and reel pricing, current stock by part number and date code, and volume discounts on bulk orders, request a bulk quotation.
