MTC20F1045S1RC48BA2R Обзор

The Micron MTC20F1045S1RC48BA2R is a 32GB DDR5 SDRAM Registered DIMM (RDIMM) module rated at 4800 MT/s, organized as 1Rx4 and operating from a 1.1V VDD supply in a 288-pin RDIMM form factor. The module integrates on-DIMM voltage regulation through the 12V-to-PMIC topology required by the DDR5 standard, allowing cleaner power delivery to the DRAM devices and reducing motherboard complexity.

A RDIMM (Registered Dual In-line Memory Module) is a type of server-class memory that places a register buffer between the DRAM devices and the memory controller. The register reduces the electrical load on the controller, enabling higher capacity and higher rank counts per channel. RDIMMs sit within the broader taxonomy of DRAM modules -> DDR5 memory -> server memory -> computer memory -> semiconductor components, and are distinguished from UDIMMs (unbuffered) and LRDIMMs (load-reduced) by their balance of capacity, rank scalability, and signal-integrity performance.

Key features of the MTC20F1045S1RC48BA2R include a 4800 MT/s data rate (PC5-38400), a base clock of 2400 MHz, 1Rx4 rank/organization, 1.1V nominal VDD, and a die revision in the A-die family. The 288-pin RDIMM edge finger conforms to the JEDEC-standard DDR5 module pinout, supporting error-correcting code (ECC) operation typical of server-class memory and making it suitable for platforms that require data integrity protection.

From an architectural standpoint, DDR5 doubles the prefetch and bank-group count of DDR4, introduces on-module PMIC for tighter voltage tolerance, and adopts decision feedback equalization (DFE) on the I/O. These changes deliver higher effective bandwidth at lower per-bit power, which is why DDR5 RDIMMs like the MTC20F1045S1RC48BA2R target mainstream server, workstation, and enterprise storage workloads where capacity per channel and throughput are the primary design constraints.

Typical applications include mainstream dual- and single-socket servers, virtualization hosts, in-memory databases, enterprise storage arrays, and content-creation workstations. For OEM platforms validated against JEDEC-standard 4800 MT/s operation, the module offers predictable compatibility and a standardized upgrade path across the DDR5 generation.

When integrating this module, verify that the host platform supports 1Rx4 32GB RDIMMs at 4800 MT/s and that the BIOS contains the appropriate SPD timings. Mixed-rank or mixed-density populations are allowed by JEDEC but may downclock; consult the platform memory population guide before deployment in production.

This page combines verified distributor pricing, parametric drop-in equivalents, and design notes beyond the raw manufacturer datasheet to support sourcing, qualification, and BOM decisions.

MTC20F1045S1RC48BA2R подходит для 6 применениеs: Mainstream Dual-Socket Servers, Enterprise Storage Arrays, Virtualization Hosts, Content-Creation Workstations, In-Memory Database Servers, Cloud Computing Compute Nodes.

🖥️

Mainstream Dual-Socket Servers

The MTC20F1045S1RC48BA2R delivers 32GB per module at 4800 MT/s, making it a strong fit for mainstream dual-socket servers that require high capacity per channel without stepping to costlier LRDIMMs. The 1Rx4 organization is supported by all current Intel Sapphire Rapids and AMD EPYC Genoa platforms, and ECC capability meets the data-integrity requirements of virtualization and consolidation workloads. Using 8 modules, a typical 2-socket server can reach 256GB without populating every channel, leaving headroom for future upgrades.

💾

Enterprise Storage Arrays

Enterprise storage controllers benefit from the MTC20F1045S1RC48BA2R's ECC RDIMM design, which corrects single-bit memory errors and detects multi-bit faults that could otherwise corrupt cached data. The 4800 MT/s bandwidth provides adequate throughput for cache write-back, and the 288-pin RDIMM form factor integrates cleanly with controllers from Broadcom, Microchip, and Marvell. For RAID cache or write-log applications, the module's 32GB capacity allows smaller module counts while preserving reliability targets.

🌐

Virtualization Hosts

Virtualization density is directly tied to memory capacity and channel bandwidth. The MTC20F1045S1RC48BA2R provides 32GB per module and 4800 MT/s throughput, enabling a host to comfortably run dozens of VMs without memory pressure. The 1Rx4 rank topology simplifies memory interleaving on Intel and AMD platforms, which is critical for achieving predictable per-VM performance. Hypervisor vendors (VMware ESXi, Microsoft Hyper-V, KVM) validate JEDEC-standard DDR5 RDIMMs, ensuring broad compatibility with the module.

🎥

Content-Creation Workstations

Professional content-creation workloads such as 8K video editing, 3D rendering, and large-scale simulation demand large memory capacity with stable throughput. The MTC20F1045S1RC48BA2R, installed in a workstation with an 8-channel platform, can populate 256GB or more of ECC-protected memory, enabling complex timelines and large scene files to remain resident. The DDR5 4800 MT/s throughput ensures that CPU and GPU compute stages are not starved by memory access, even under parallel pipelines.

🗄️

In-Memory Database Servers

In-memory databases like SAP HANA, Redis, and MemSQL are sized by available RAM. The MTC20F1045S1RC48BA2R at 32GB per module allows database nodes to scale into the terabyte range with modest DIMM counts, reducing power per GB and improving reliability through fewer connector points. The 1.1V DDR5 operation reduces memory subsystem power versus DDR4 at equivalent capacity, which matters for large-memory nodes where cooling and energy dominate operating cost.

☁️

Cloud Computing Compute Nodes

Hyperscale and cloud service providers deploy compute nodes at scale, where memory capacity, cost per GB, and supply continuity all matter. The MTC20F1045S1RC48BA2R offers a JEDEC-standard 32GB 1Rx4 4800 RDIMM that is interchangeable across Intel and AMD reference platforms. Multi-vendor qualification (Micron, Samsung, SK Hynix) supports dual-source procurement strategies that cloud operators rely on for capacity planning and supply-chain resilience.

Заметки по проектированию

DDR5 RDIMMs dissipate measurable power under sustained workloads - the MTC20F1045S1RC48BA2R at 1.1V with 32GB density typically draws 8-12W per module under load. Ensure front-to-back airflow across the DIMM banks at the rated platform CFM, and avoid stacking heat-producing devices directly above the DIMM sockets. A failed thermal margin is one of the leading causes of bit-error rate spikes in populated servers.

Do not mix 1Rx4 modules of different die revisions within the same channel without consulting the platform memory population guide. Although JEDEC allows mixed-rank populations, mixing A-die and other revisions can trigger BIOS downclocking to the slowest common speed, silently reducing bandwidth. The MTC20F1045S1RC48BA2R ships from the A-die revision family - verify with the SPD label before mixing.

DDR5 introduces on-module PMIC and decision feedback equalization; platform validation against the JEDEC reference topology is strongly recommended before deploying MTC20F1045S1RC48BA2R modules in custom motherboards. The DIMM socket, mid-loss PCB material, and routing length tuning should follow the CPU vendor's DDR5 design guide to avoid intermittent training failures at boot.
