M323R1GB4BB0-CQK

High-Performance DDR5 UDIMM Server Memory Module for Entry Platforms with the M323R1GB4BB0-CQK

The M323R1GB4BB0-CQK is a Samsung DDR5 UDIMM designed for entry servers and workstation-class platforms that require JEDEC-compliant memory behavior with predictable latency and power characteristics. Built as a 1 x 8GB unbuffered module at 4800 MT/s (PC5-38400U) and 1.1V, the M323R1GB4BB0-CQK supports stable platform bring-up and incremental capacity expansion without introducing registered-buffer dependencies.

Architecturally, the M323R1GB4BB0-CQK aligns with modern CPU memory controllers that benefit from DDR5’s improved channel efficiency and tighter signal integrity requirements on 288-pin UDIMM layouts. The single-rank x16 organization and CL40 timings suit light virtualization, OS and hypervisor validation, and edge appliances where PCIe Gen4/Gen5 expansion and NVMe storage performance are priorities, but memory capacity per node must remain controlled. With low-profile module height, the M323R1GB4BB0-CQK integrates cleanly in compact chassis and airflow-constrained builds, supporting consistent thermals alongside high-density I/O configurations.

Why Choose the M323R1GB4BB0-CQK?

The M323R1GB4BB0-CQK provides a pragmatic density-to-performance balance for DDR5 UDIMM platforms, enabling standardized deployments across lab nodes, edge clusters, and entry compute tiers. Its JEDEC-focused design simplifies scaling decisions and reduces integration risk when validating CPU generations, storage backplanes, and PCIe topologies in repeatable configurations.

Samsung engineering emphasizes signal integrity, production consistency, and qualification discipline to meet enterprise uptime expectations. The module’s DDR5 operating envelope and on-die ECC behavior are designed to align with current data center standards for power efficiency and controlled thermal loading.

Key Applications:

Entry server and workstation memory upgrades
Lab and development validation nodes
Edge appliances and compact systems
Hardware bring-up and platform qualification

At Happyware - Server Hardware you benefit from non-binding offers tailored to your rollout plan for M323R1GB4BB0-CQK deployments, with extended warranty options up to 6 years to protect long-life edge and lab investments.
