Designed for server-class platforms, this DDR5-4800 RDIMM with ECC and registered signaling is ideal for memory-intensive workloads such as virtualization, in-memory databases, and mission-critical enterprise applications. Its dual-rank x4 organization maximizes memory bandwidth and capacity utilization per channel, while the on-module register and ECC ensure signal stability and data integrity under sustained heavy load.
1. Error Correcting Code protection detects and corrects single-bit memory errors, preserving data integrity in always-on server environments where even a single undetected flip can corrupt financial transactions or hypervisor state.
2. Registered signal buffering isolates the memory controller from the electrical load of multiple DIMMs, enabling fully populated server boards to maintain stable signal timing under heavy memory throughput.
3. Dual-rank organization increases the interleaving depth on each channel, allowing the memory controller to overlap commands and keep data buses fully utilized during intense virtual machine consolidation.
4. Generous per-module capacity provides the dense memory footprint required to host large in-memory databases and massive container fleets without resorting to costly, latency-prone memory tiering.
5. DDR5 architecture delivers significantly higher internal bandwidth and bank counts, accelerating parallel access patterns in analytics and AI inference workloads that stream enormous datasets continuously.
The M321R4GA0BB0-CQKET is a server-grade DDR5 RDIMM built for enterprise workloads where every bit of data matters. Its ECC technology actively detects and corrects single-bit memory errors, a silent threat that can corrupt financial transactions or trigger VM crashes in dense virtualization clusters. In a Hyper‑V or VMware farm running dozens of virtual machines, that hardware‑level integrity means you avoid unexplained application faults and maintain regulatory compliance without performance‑robbing software workarounds. The registered signal buffer is equally vital: by isolating the memory controller from the electrical load of high‑capacity modules, it lets you populate all DIMM slots with 32 GB sticks without sacrificing signal quality. This directly translates into stable, large‑memory configurations for in‑memory databases like SAP HANA or Redis, where a single node might demand terabytes of reliable RAM to keep latency in microseconds. Dual rank x4 organization further multiplies bandwidth through parallel access across internal banks, so real‑time analytics queries that sweep across massive datasets complete faster, while the 1.1V DDR5 core and 4800 MT/s speed deliver that extra bandwidth at lower power per bit than previous generations—critical when your server farm is measured in kilowatts. Together, these features ensure that your virtualized infrastructure and high‑speed databases run with the predictability and uptime your business demands, without compromise.
General Virtualization
Populate one DIMM per channel to maximize bandwidth. In a dual-socket platform with eight memory channels per CPU, install eight 32 GB modules per processor for 256 GB per socket (512 GB total). This configuration balances cost, density, and DDR5-4800 speed for mixed VM environments.
In-Memory Database
Maximize capacity and data integrity. Populate all slots, using two DIMMs per channel if available; speed may downshift. A dual-socket server with sixteen DIMM slots per CPU can reach 1 TB with 32 × 32 GB RDIMMs. ECC and register buffering provide the reliability required by large-scale databases.
High-Performance Computing (HPC)
Focus on memory bandwidth. Install one DIMM per channel to sustain 4800 MT/s. A dual-socket node with eight populated channels each using a single 32 GB module delivers 256 GB of high-speed memory, ideal for simulation and modelling tasks.
Rigorously tested server memory, compatible with Dell PowerEdge R760, HPE ProLiant DL380 Gen11, Lenovo ThinkSystem SR650 V3, and more.
Q: Can I mix this M321R4GA0BB0-CQKET with other memory modules of different brands or speeds?
A: Mixing different brands or speeds is not recommended for server RDIMMs. It may cause stability issues or boot failures. For guaranteed compatibility, always use identical modules with the same MPN and rank in your server.
Q: Is this memory compatible with my system?
A: This DDR5-4800 Registered ECC module is designed for servers with Intel Xeon Scalable (Sapphire Rapids) or AMD EPYC 9004 platforms. Please confirm this specific MPN is listed on your server board’s qualified vendor list.
Q: What is the recommended DIMM population order for optimal performance?
A: For optimal performance, populate identical RDIMMs per channel following your server manual’s population guidelines. In dual-socket configurations, balance memory across processors and populate symmetrical slots to enable interleaving.
Q: Does this module support overclocking or XMP profiles?
A: No. This enterprise Registered DDR5 ECC module operates strictly at JEDEC standard 4800MT/s. It does not support overclocking or XMP profiles, as it prioritizes 24/7 stability and data integrity for mission-critical workloads.
Q: What warranty and typical failure rate can I expect?
A: This module is covered by a 1-year warranty. Enterprise-class RDIMMs like this typically exhibit an annualized failure rate (AFR) well under 1%, ensuring high reliability for demanding server environments.
