Designed for enterprise servers, this DDR5-4800 Registered DIMM with ECC and a dual-rank x4 organization ensures data integrity and stable operation under heavy loads, making it ideal for memory-intensive workloads such as virtualization, in-memory databases, and mission-critical applications where reliability is paramount. The registered signal type buffers command and address signals to enable higher density configurations on 288-pin platforms, while the dual-rank design leverages interleaving to improve effective bandwidth and mitigate latency at the rated CL40 timing.
1. ECC memory protection silently corrects single-bit errors, preventing silent data corruption in financial transactions and critical database operations.
2. Registered signal buffering stabilizes high-capacity memory channels, allowing dense server configurations to scale without compromising signal integrity under heavy load.
3. DDR5 technology doubles burst length and delivers higher bandwidth per core, directly accelerating real-time analytics and in-memory computing frameworks.
4. Dual Rank x4 organization interleaves memory accesses across internal banks, sustaining throughput even under mixed workload patterns typical of multi-tenant cloud environments.
5. The 32GB capacity per module maximizes virtual machine density, enabling more simultaneous users or containers without hitting memory contention on a single node.
Designed specifically for enterprise servers, the Samsung M321R4GA0BB0-CQKEG RDIMM is engineered to eliminate the downtime and data corruption that keep IT managers awake at night. Its ECC technology continuously detects and corrects single-bit memory errors caused by cosmic radiation or electrical noise, which is non-negotiable in financial transaction databases or healthcare records where a silent bit flip could mean a multimillion-dollar discrepancy or a compromised patient file. The registered signal buffer stabilizes the command and address lines across densely populated server boards, so a virtualization cluster running dozens of VMs on a single node won’t suffer signal degradation or sudden reboots when all 32GB per stick are under heavy simultaneous access. Meanwhile, the dual-rank x4 architecture interleaves memory banks to maximize channel utilization, dramatically boosting throughput for in-memory analytics platforms like SAP HANA or large-scale Redis caches that demand low-latency, parallel data streams. Operated at a power-efficient 1.1V and DDR5-4800 speed, this module delivers the consistent performance envelope and reliability that mission-critical workloads require around the clock, making unplanned outages a rarity rather than a routine emergency call.
Capacity Planning for 32GB DDR5-4800 RDIMM
This memory module is a 32GB DDR5 Registered ECC DIMM (Dual Rank x4) designed for servers. Below are configuration guidelines for typical enterprise workloads.
General Virtualization
Populate all memory channels uniformly with one DIMM per channel (1DPC) to balance capacity and bandwidth. For a dual‑socket server with eight channels per CPU, install 16 modules (512 GB total). This maintains the full 4800 MT/s speed and delivers stable performance for multiple VMs.
In-Memory Database
Maximize capacity by installing two DIMMs per channel (2DPC) despite a slight speed drop to 4000–4400 MT/s. Fully populating a 2‑socket platform with 16 DIMM slots per socket provides 1 TB (32 × 32 GB), ideal for large Redis or SAP HANA instances. ECC and registered buffering protect data integrity.
High-Performance Computing
Prioritize bandwidth by using only one DIMM per channel to avoid downclocking. Equip each socket with 8 or 12 modules (256–384 GB) so the system runs consistently at 4800 MT/s. The dual‑rank x4 construction already ensures high throughput per module for parallel simulation and modeling tasks.
Rigorously tested compatibility with Dell R760, HPE DL360 Gen11, Lenovo SR650 V3, and other DDR5 servers.
Q: Can I mix this M321R4GA0BB0-CQKEG with other memory modules of different brands or speeds?
A: Mixing RDIMMs of different brands or speeds is not recommended. This can lead to signal integrity issues, reduced stability, or system failure. Always populate identical modules for validated server environments.
Q: Is this memory compatible with my system?
A: This DDR5-4800 ECC Registered DIMM is designed for servers using Intel Xeon Scalable (4th Gen+) or AMD EPYC 7004 series CPUs. Confirm your server board's Qualified Vendor List (QVL) for exact compatibility.
Q: What is the recommended DIMM population order for optimal performance?
A: Populate identical DIMMs per channel, filling the farthest slot from the CPU first. For dual-socket servers, balance memory across both processors. Always follow your server manufacturer's specific population guidelines.
Q: Does this module support overclocking or XMP profiles?
A: No. This enterprise RDIMM adheres strictly to JEDEC DDR5-4800 standards for 24/7 reliability. It does not support XMP profiles or overclocking, which are avoided in server environments to ensure data integrity.
Q: What warranty and typical failure rate can I expect?
A: This module includes a 1-year warranty. Manufactured with premium components and rigorous testing, our RDIMMs achieve an extremely low annualized failure rate, typically well below 0.1%.
