Samsung M321R4GA0EB2-CCP 32G DDR5 6400 RDIMM
The Samsung M321R4GA0EB2-CCP is a 32GB DDR5 memory module aimed at system integrators and IT buyers upgrading desktop workstations and DDR5-based compute platforms. With on-die ECC and a JEDEC-standard DDR5 design, it suits general-purpose compute, workstation, and entry high-performance computing workloads. Note that listings reference both RDIMM and UDIMM form factors for this part, so confirm the buffered/unbuffered requirement of your platform before ordering.

Good to know
- DDR5 modules are not backward or forward compatible: DDR5 will not slot into DDR4/DDR3 boards, and within DDR5 platforms, registered (RDIMM) and unbuffered (UDIMM) modules should not be mixed. Always match the memory type your motherboard or server platform explicitly supports.
- Within the DDR5 family, on-die ECC provides error checking inside the DRAM chip itself — an improvement over consumer DDR4 — but it is not equivalent to full registered ECC RDIMMs used in mission-critical servers, so workload criticality should guide your choice.
- Buying tip: the source data shows conflicting speed (4800 MT/s vs. 6400 in the title) and buffered/unbuffered type; request the exact datasheet and part marking photos from your supplier before committing to volume, since real data rate is also limited by your platform’s supported JEDEC profiles.
For tray and reel pricing, current stock by part number and date code, and volume discounts on bulk orders, request a bulk quotation.
