This 32 GB DDR5-4800 RDIMM with ECC and registered signaling is purpose-built for server platforms handling memory-intensive virtualization, in-memory databases, and mission-critical workloads where data integrity is non-negotiable. Its dual-rank x4 configuration maximizes bank-level parallelism to sustain high throughput under heavy load, while the CL40 latency and 1.1 V operating voltage deliver a balanced mix of responsiveness and power efficiency in dense rack deployments.
1. ECC memory detects and corrects single-bit errors in real time, preventing silent data corruption in financial transactions and critical databases that demand 24/7 accuracy.
2. Registered signal type buffers command and address signals, enabling the high-capacity memory configurations that large-scale virtualization and in-memory analytics clusters rely on for stable scaling.
3. 32 GB capacity per module maximizes density for virtualized workloads, allowing more active VMs per server without compromising memory headroom under heavy consolidation.
4. Dual Rank x4 organization interleaves memory accesses across multiple internal banks, sustaining throughput and reducing latency in bandwidth-sensitive HPC and AI inference tasks.
5. DDR5-4800 speed doubles the burst length and delivers substantial bandwidth improvements, accelerating real-time data ingestion and large-dataset processing in cloud-native environments.
This DDR5-4800 Registered DIMM, part number MTC20F2085S1RC48BR, is purpose-built for the relentless demands of modern server infrastructure. Its four core attributes directly translate into reliability and performance where it matters most.
In a virtualized cluster hosting dozens of VMs, ECC memory becomes your silent guardian. It actively corrects single-bit errors that cosmic radiation or electrical noise can introduce, preventing silent data corruption that could crash critical applications or corrupt financial transactions without warning. The registered signal type then steps in with an on-chip clock buffer, sharply reducing electrical load on the memory controller. This means you can fully populate channels with high-capacity modules to scale to terabytes of RAM, all while maintaining rock-solid signal integrity for 24/7 operations.
The dual-rank x4 organization is a throughput multiplier for memory-intensive databases like SAP HANA or Redis. By allowing simultaneous access across two internal rank groups, it significantly boosts bandwidth and reduces latency under the heavy, parallel query loads that define real-time analytics. Every millisecond saved in an in-memory database directly accelerates business decisions. Finally, operating at a mere 1.1 volts, this 32GB module delivers DDR5’s massive bandwidth with superior energy efficiency, curbing power and cooling costs across your server farm without ever trading away the data integrity your enterprise depends on.
Given the ECC, Registered (RDIMM) DDR5-4800 specification, this is server memory. For two-socket platforms, 8-channel configurations are typical, so populate in multiples of 8 DIMMs for balanced bandwidth. Below are capacity planning guidelines for three key workloads using this 32 GB RDIMM.
General Virtualization
Start with 8 modules (256 GB) across one CPU’s memory channels for a moderate consolidation ratio. For heavy VM density, scale to 16 modules (512 GB) to populate all channels on both sockets and avoid NUMA bottlenecks while leaving headroom for failover.
In-Memory Database
Populate fully with 16 modules (512 GB) on a dual-socket system to maximize capacity and interleaved bandwidth. For larger datasets, consider 24 modules (768 GB) if the platform allows balanced 3-DPC, but monitor drop in speed; prioritize low latency and high rank interleaving with dual-rank x4 parts.
High Performance Computing (HPC)
Use 8 modules (256 GB) per node to deliver 8-channel bandwidth and 4 GB/core for typical simulation codes. For memory-bound jobs, scale to 16 modules (512 GB) while keeping ranks symmetric across IMCs to maintain peak STREAM bandwidth and deterministic performance.

Q: Can I mix this MTC20F2085S1RC48BR with other memory modules of different brands or speeds?
A: Mixing RDIMMs with different brands, speeds, or ranks is not recommended in server environments. It can lead to signal integrity issues, instability, or system boot failures due to strict platform validation requirements.
Q: Is this memory compatible with my system?
A: This DDR5-4800 ECC Registered DIMM is designed for server platforms supporting scalable Intel Xeon or AMD EPYC processors. Please verify your server board's Qualified Vendor List (QVL) for this specific 32GB DRx4 RDIMM part number.
Q: What is the recommended DIMM population order for optimal performance?
A: Refer to your server motherboard manual for the exact slot numbering. Generally, populate identical DIMMs in sets of eight for balanced memory channels, starting with the farthest slots from the CPU per channel to maximize signal integrity.
Q: Does this module support overclocking or XMP profiles?
A: No. This JEDEC-compliant server RDIMM runs at a fixed 4800 MHz with CL40 timings. It does not support XMP or manual overclocking, as stability and data integrity via ECC are prioritized over frequency tuning in enterprise platforms.
Q: What warranty and typical failure rate can I expect?
A: This module is covered by a one-year warranty. Enterprise-class RDIMMs exhibit an extremely low annualized failure rate (AFR), typically under 0.5%, ensuring high reliability in 24/7 data center operations.
