This is a server-grade DDR5 RDIMM, purpose-built for enterprise platforms handling virtualization, in-memory databases, and mission-critical workloads where data integrity is non-negotiable. Its registered signal architecture with ECC and a single-rank x4 configuration ensures robust signal stability and low CAS latency of CL40, maximizing memory bandwidth and fault tolerance under continuous load.
1. Ample density per module accelerates virtual machine consolidation and in-memory database performance without occupying extra DIMM slots.
2. DDR5 technology delivers a generational leap in bandwidth and energy efficiency, essential for next-gen server throughput.
3. The high-speed interface saturates memory channels with data, slashing latency in real-time analytics and AI inference workloads.
4. ECC protection silently corrects single-bit errors, preserving data integrity and preventing costly system crashes in mission-critical operations.
5. Registered buffering strengthens signal integrity across fully populated server boards, ensuring rock-solid stability under maximum memory loads.
The Samsung M329R4GA0BB0-CQKDG is a 32GB DDR5 registered server memory module engineered for mission-critical enterprise environments. Its ECC technology actively detects and corrects single-bit memory errors, a vital defense against silent data corruption that could crash virtual machines or compromise financial transactions in a virtualized cluster. The registered (RDIMM) design buffers command and address signals, enabling stable operation when populating all memory channels to maximize capacity—crucial for in-memory databases like SAP HANA where even momentary instability translates into lost revenue. With DDR5-4800 speed and a column access strobe latency of just 4 cycles, this module delivers ultra-responsive data access for latency-sensitive applications, ensuring that hundreds of virtual desktops or containerized microservices run without perceptible lag. Operating at just 1.1V, it significantly reduces thermal output and energy costs over generations, directly improving total cost of ownership across a server fleet. Whether you are scaling a VMware cluster or accelerating Redis workloads, this memory provides the reliability, density, and power efficiency your infrastructure depends on.
General Virtualization
For a DDR5-4800 registered ECC module of 32 GB capacity, a balanced virtualization host should be configured with at least eight identical modules to populate one DIMM per channel on a typical 8-channel server platform, delivering 256 GB total memory. This provides sufficient capacity for 40–60 moderate virtual machines while ensuring channel interleaving and memory bandwidth efficiency. Always install in multiples of eight to maintain balanced memory access and avoid NUMA performance penalties.
In-Memory Database
In‑memory databases like SAP HANA or Redis demand both capacity and resilience, making ECC RDIMMs essential. A single 32 GB RDIMM may serve a small test instance, but production servers should deploy twelve modules across all memory channels for 384 GB capacity. Configure memory sparing or rank mirroring if the platform supports it, and ensure each channel uses a single rank x4 module to minimize latency while upholding data integrity under sustained load.
High Performance Computing
HPC workloads such as computational fluid dynamics or genomic analysis benefit from a fully populated memory configuration to maximize bandwidth. Install two 32 GB RDIMMs per channel for a total of 16 modules (512 GB) if the server supports two DIMMs per channel at DDR5-4800 speeds. This populates both channels equally while keeping the memory frequency at the rated 4800 MT/s; single‑rank x4 DIMMs reduce electrical loading, helping maintain clock stability during intense parallel processing.
Rigorously tested and compatible with Dell PowerEdge R760, HPE ProLiant DL380 Gen11, Lenovo ThinkSystem SR650 V3, and Supermicro SYS-220P-C9R.
Q: Can I mix this M329R4GA0BB0-CQKDG with other memory modules of different brands or speeds?
A: Mixing RDIMMs of different brands or speeds is not recommended. This DDR5 registered module relies on strict matching for signal integrity. Mixing can lead to system instability or failure to POST.
Q: Is this memory compatible with my system?
A: This 32GB DDR5-4800 registered ECC module is designed for server platforms supporting DDR5 RDIMM, such as Intel Xeon Scalable (Sapphire Rapids) or AMD EPYC 7003/9004. Verify your motherboard's QVL for specific compatibility.
Q: What is the recommended DIMM population order for optimal performance?
A: For optimal performance, populate one DIMM per memory channel first, filling identical slots symmetrically across both processor sockets. Always consult your server motherboard's population guide for balanced interleaving.
Q: Does this module support overclocking or XMP profiles?
A: No. As a server-grade DDR5 registered DIMM, it operates strictly at JEDEC-standard DDR5-4800 with no XMP or overclocking support. Stability and data integrity are prioritized over higher frequencies.
Q: What warranty and typical failure rate can I expect?
A: This module includes a 1-year warranty. Enterprise-class DDR5 RDIMMs typically exhibit an annualized failure rate (AFR) below 0.5% under normal operating conditions, ensuring high reliability for mission-critical workloads.
