This 32 GB DDR5-4800 RDIMM with ECC and an exceptionally low CAS latency of 4 cycles is purpose-built for enterprise-class servers, delivering the data integrity and responsiveness demanded by memory-intensive virtualization, in-memory databases, and mission-critical workloads. Its single-rank x4 configuration and registered signal architecture further enhance signal integrity and enable reliable, high-density memory scaling in multi-DIMM platforms.
1. 32GB capacity per module allows dense memory configurations, enabling more virtual machines per physical host without sacrificing performance.
2. DDR5 technology doubles the peak bandwidth over previous generations, crucial for accelerating real-time analytics and in-memory databases.
3. On-die ECC automatically corrects single-bit errors, safeguarding data integrity in mission-critical enterprise workloads.
4. Registered signal buffering stabilizes command and address signals, supporting large-scale memory installations vital for high-density virtualization.
5. Single-rank x4 organization minimizes electrical loading on the channel, delivering lower latency and cleaner signals in multi-DIMM server configurations.
The M329R4GA0BB0-CQKVG is a 32GB DDR5-4800 Registered DIMM engineered for enterprise servers, and its four core strengths directly resolve the critical pain points of data center operations. First, the DDR5-4800 bandwidth eliminates throughput bottlenecks in memory-hungry in-memory databases like Redis or SAP HANA, where sub-millisecond query responses depend on massive concurrent data streams. Second, integrated ECC error correction actively detects and repairs single-bit flips caused by background radiation, which is non-negotiable for virtualized clusters hosting dozens of VMs; a single uncorrected error there can silently corrupt transactions or crash hypervisors. Third, the registered clock driver buffers command signals to maintain rock-solid electrical stability when you fully populate a server board, letting you scale to terabytes reliably for dense virtual desktop infrastructure hosts. Fourth, the 32GB capacity combined with a single-rank x4 organization strikes an ideal balance—it provides ample headroom for multi-tenancy while reducing rank-switching latency, so multi-VM environments feel snappier. The 1.1V operation also lowers your total cooling costs. From ensuring financial transaction integrity to consolidating your virtualization fleet, this DIMM turns specifications into real uptime, data fidelity, and consistent performance that your workloads demand.
General Virtualization
Populate at least four identical 32GB RDIMMs (128 GB total) in a balanced multi‑channel configuration to maximize VM density and maintain symmetric memory access. A one‑DIMM‑per‑channel (1DPC) layout guarantees full DDR5‑4800 speed; moving to two DIMMs per channel increases capacity but may require a slight frequency trade‑off. ECC and registered buffering ensure the data integrity that multi‑tenant hypervisors demand.
In‑Memory Database
Latency‑sensitive databases benefit from the lowest possible access times, so fill every memory channel with one of these single‑rank x4 RDIMMs. An 8‑channel system populated with 8 × 32 GB modules (256 GB) delivers maximum bandwidth and uses rank interleaving to hide refresh overhead. ECC is non‑negotiable here to prevent silent data corruption in critical, in‑memory working sets.
High‑Performance Computing
HPC codes are often memory‑bandwidth bound; therefore, install one 32 GB RDIMM per channel across all available channels to sustain the rated DDR5‑4800 transfer rate. In a dual‑socket server this translates to 16 identical modules (512 GB total), offering both the capacity for large simulation meshes and the high throughput needed for vectorized math libraries. The registered, single‑rank construction preserves signal integrity under heavy, sustained load.
Rigorously tested to ensure compatibility with Dell PowerEdge R760, HPE ProLiant DL380 Gen11, Lenovo ThinkSystem SR650 V3, and Supermicro SYS-221H-TNR.
Q: Can I mix this M329R4GA0BB0-CQKVG with other memory modules of different brands or speeds?
A: Mixing is strongly discouraged. Server platforms demand matched RDIMMs for signal integrity. Mixed brands, speeds, or ranks often cause POST failures or instability. Maintain identical MPN across all channels.
Q: Is this memory compatible with my system?
A: This DDR5-4800 Registered ECC RDIMM is validated for modern server platforms such as Intel Xeon Scalable (Sapphire Rapids) and AMD EPYC (Genoa). Confirm support via your motherboard’s memory QVL or chipset compatibility list.
Q: What is the recommended DIMM population order for optimal performance?
A: Adhere to your server vendor’s guide. Typically, populate the farthest slot from the CPU per channel first. With Single Rank x4 modules, balance all populated memory channels symmetrically for maximum bandwidth and interleaving.
Q: Does this module support overclocking or XMP profiles?
A: No. As a server-grade Registered ECC module, it adheres strictly to JEDEC standards. It has no XMP or overclocking support; reliability and data integrity take precedence, running at the rated 4800MT/s CL40.
Q: What warranty and typical failure rate can I expect?
A: This module includes a 1-year warranty. Enterprise RDIMMs demonstrate very low annualized failure rates (AFR), typically under 0.5%, engineered for 24/7 operations. Defective units are promptly replaced during the warranty period.
