Samsung M321R4GA3BB6-CQKET 32GB 2Rx8 DDR5-4800 RDIMM – Enterprise Server Memory
The Samsung M321R4GA3BB6-CQKET (32GB 2Rx8 PC5-4800B-RE0-1010-XT) is a genuine enterprise-grade DDR5 Registered ECC (RDIMM) server memory module engineered to maximize the compute efficiency of next-generation rack and tower servers. Built with Samsung's high-density DDR5 DRAM architecture, dual-rank x8 organization, and on-module power management, it delivers exceptional memory bandwidth and rock-solid stability for virtualization clusters, in-memory databases, and cloud infrastructure.
Key Advantages & Features
- 4800 MT/s High-Throughput Performance: Operating at 4800 MT/s (PC5-4800B / PC5-38400), this module delivers a massive bandwidth leap over DDR4 server memory to keep high-core-count processors fed without bottlenecks.
- Dual Rank x8 (2Rx8) Organization: Utilizes two ranks of x8 DRAM chips to maximize memory bank interleaving, improving concurrency and overall throughput across server memory channels.
- EC8 Registered ECC Protection: Combines DDR5 On-Die ECC with full system-level 8-bit ECC (EC8) and registered command/address buffering to detect and correct memory errors before they cause crashes or data corruption.
- 1.1V Low-Voltage Design with Integrated PMIC: On-DIMM Power Management IC (PMIC) handles local voltage regulation cleanly at 1.1V, reducing power draw and heat dissipation inside dense server chassis.

Frequently Asked Questions
Q: Can I mix 2Rx8 DDR5 modules with 1Rx8 or 2Rx4 modules in the same server?
For optimal memory channel balance and stability, server manufacturers recommend populating memory slots with matching ranks and capacities per channel. Check your server's memory population guide before mixing 2Rx8 modules with other ranks.
Q: Will this module work in a DDR4 server or a standard desktop PC?
No. This is a DDR5 Registered ECC (RDIMM) enterprise server module. It will not fit DDR4 slots and is not compatible with consumer desktop motherboards that require Unbuffered (UDIMM) memory.
