Designed for enterprise server platforms, this 48 GB DDR5-5600 Registered DIMM leverages integrated ECC and a Registered signal type to ensure data integrity and signal stability under heavy load. Its dual-rank x8 configuration maximizes memory bandwidth and interleaving efficiency, making it ideal for memory-intensive workloads such as virtualization, in-memory databases, and large-scale data analytics.
1. The 48 GB capacity per module allows for denser memory configurations in a limited number of slots, giving virtualized servers the headroom to host more VMs and larger in-memory databases without scaling out hardware.
2. DDR5 technology brings on-die ECC and doubled bank groups, strengthening data reliability while sustaining the parallel memory access patterns common in multi-tenant cloud workloads.
3. Operating at 5600 MHz, the module delivers higher sustained bandwidth that cuts through memory bottlenecks during real-time analytics and high-frequency financial transactions.
4. Side-band ECC actively detects and corrects single-bit errors, preventing silent data corruption in environments where long-running computations and data integrity are non-negotiable.
5. Registered signal buffering stabilizes command and address lines across heavily loaded channels, making large-scale memory provisioning safe in multi-socket servers without signal degradation.
When you are running a virtualized cluster or an in-memory database, every unseen memory error and every microsecond of latency directly hits your bottom line. The Micron MTC20F208XS1RC56BB1R is a 48 GB DDR5-5600 RDIMM engineered to eliminate those exact risks. Its ECC technology silently corrects single-bit flips caused by background radiation, which in a multi-tenant VMware farm means one corrupted transaction will not cascade into a node failure. The registered signal buffer stabilizes the command path across fully populated servers, so even if you expand to 24 DIMMs per host for heavy consolidation, the IMC sees a clean, deterministic load and you avoid random boot failures or memory training dropouts. That stability pairs with the dual-rank x8 organization to deliver rank interleaving, noticeably increasing read bandwidth for Redis and SAP HANA by keeping the data pipeline busy while one rank refreshes. And because the module operates at just 1.1 V with 5600 MHz transfer rates, you gain nearly 50% more peak bandwidth than a standard DDR4-2933 LRDIMM without raising thermal stress. This means your database instances serve more queries per second inside the same power envelope, and your cluster nodes maintain consistent performance during end-of-month batch processing, turning memory from a potential bottleneck into a strategic asset for uptime and throughput.
This 48GB DDR5-5600 Registered ECC module is server memory (RDIMM). Below is capacity planning guidance for typical workloads.
General Virtualization
Populate all memory channels symmetrically with 48GB RDIMMs to optimize bandwidth and NUMA. In an 8-channel dual-socket server, one DIMM per channel (16 modules) provides 768GB, sufficient for dozens of VMs. Scaling to two DIMMs per channel raises capacity to 1.5TB for dense consolidation while maintaining performance.
In-Memory Database
Equip each CPU with identical 48GB RDIMMs across all channels. A 1-DIMM-per-channel layout yields 384GB, ideal for Redis or mid-sized caches; moving to 2 DIMMs per channel expands capacity to 768GB for larger datasets. For multi-terabyte in-memory databases, fully populate a dual-socket server to reach 1.5TB with ECC protection.
High-Performance Computing
Maximize bandwidth by installing one 48GB DIMM per channel to run at full DDR5-5600 speed without downclocking, delivering 384GB per socket for simulation codes. When memory capacity limits scaling, use two DIMMs per channel to achieve 768GB per socket, accepting a slight frequency reduction for greater working set size.
Rigorously tested: guaranteed compatibility with Dell PowerEdge R760, HPE ProLiant DL380 Gen11, and Lenovo ThinkSystem SR650 V3.
Q: Can I mix this MTC20F208XS1RC56BB1R with other memory modules of different brands or speeds?
A: Mixing is not recommended for server environments. Different brands or speeds may cause signal integrity issues and instability. For optimal reliability, always use identical modules in all channels according to your server's qualified vendor list.
Q: Is this memory compatible with my Intel Xeon or AMD EPYC server platform?
A: This DDR5-5600 ECC RDIMM is compatible with platforms supporting DDR5 registered memory, such as Intel Xeon Scalable (Sapphire Rapids) and AMD EPYC 9004 series. Verify your motherboard's memory QVL to ensure compatibility.
Q: What is the recommended DIMM population order for optimal performance?
A: Follow your server's memory population guidelines. Generally, populate symmetrical channels per CPU, fill the farthest slots in each channel first, and balance capacity across memory controllers for maximum bandwidth and interleaving.
Q: Does this module support overclocking or XMP profiles?
A: No. As an enterprise-grade ECC RDIMM, this module adheres strictly to JEDEC DDR5-5600 (PC5-44800) standards. It does not support XMP or overclocking, ensuring stability and data integrity in mission-critical server workloads.
