Samsung M321R2GA3EB2-CCP 16G DDR5 6400 RDIMM
The Samsung M321R2GA3EB2-CCP is a 16GB DDR5 UDIMM module built for desktop PCs, workstations, entry-level servers, and high-performance computing systems. It targets buyers upgrading to the DDR5 platform who need JEDEC-standard capacity with on-die ECC for improved data reliability. Note that because this is an unbuffered UDIMM, it should not be mixed with registered (RDIMM) modules on the same memory channel — verify your platform’s supported module type before ordering.
Key specifications (table)
| Parameter | Specification |
| Model Number | M321R2GA3EB2-CCP |
| Brand | Samsung |
| Memory Type | DDR5 UDIMM |
| Capacity | 16GB |
| Data Rate | 4800 MT/s (JEDEC base DDR5 speed grade; actual rate is platform dependent) |
| Speed Grade | PC5-38400 |
| Rank Configuration | 1Rx8 (single rank; leaves headroom for channel population on two-DIMM-per-channel boards) |
| ECC Feature | On-Die ECC (detects and corrects errors within the DRAM; not a substitute for full bus-level ECC in registered server configurations) |
| Operating Voltage | 1.1V (lower than DDR4’s standard voltage) |
| Pin Count | 288-pin (not compatible with DDR4 288-pin modules despite similar count) |
| Form Factor | UDIMM (Unbuffered DIMM) |
| DRAM Organization | x8-based DRAM |
| Compliance | JEDEC DDR5 Standard |
| Operating Temperature | 0°C to 85°C |
| Applications | Desktop PCs, Workstations, Entry-Level Servers, and High-Performance Computing Systems |
Good to know
- Compatibility: As a DDR5 UDIMM, this module fits only DDR5 UDIMM slots (consumer desktop and entry workstation/server boards). It cannot be combined with RDIMMs or installed in registered-memory server platforms, and DDR4/DDR5 generations are not interchangeable.
- Within its family: This single-rank (1Rx8) 16GB module represents Samsung’s entry DDR5 UDIMM tier at the 4800 MT/s JEDEC speed point, suited as a balanced base-module option for channel population rather than top-speed enthusiast builds.
- Buying tip: Before purchasing, confirm your motherboard’s qualified vendor list (QVL) and maximum speed per populated channel — installing one DIMM per channel typically helps the system run modules at their rated 4800 MT/s speed.
