MTC20F2085S1RC48BR Übersicht
A Registered DIMM (RDIMM) is a type of memory module used in servers and workstations in which address and command signals are buffered by a register chip between the memory controller and the DRAM devices. This buffering reduces electrical loading on the memory controller, allowing higher-capacity and higher-density memory populations than unbuffered UDIMMs. RDIMMs sit within the memory module hierarchy of DRAM -> DDR5 SDRAM -> registered memory module, and they include on-module ECC (Error Correction Code) to detect and correct single-bit memory errors for data integrity.
Key features of the MTC20F2085S1RC48BR include 32GB capacity in a dual-rank x8 configuration, PC5-38400 bandwidth at DDR5-4800 data rates, CL40 CAS latency, and 1.1V operation that lowers power consumption versus DDR4 equivalents. DDR5 moves the power management to an on-module PMIC (Power Management IC) and doubles bank groups versus DDR4, improving effective bandwidth and channel efficiency.
Technically, this RDIMM uses registered address/command signaling with ECC, making it suitable only for server platforms with registered-memory controllers. It is NOT compatible with desktop UDIMM slots and cannot be mixed with unbuffered or load-reduced (LRDIMM) modules in the same channel.
Typical applications include general-purpose server hosts, edge compute nodes, virtualization hosts with moderate VM density, and OEM server builds from vendors such as Dell PowerEdge and HPE ProLiant platforms using Intel Xeon Scalable (including Sapphire Rapids) processors.
Design consideration: always populate memory channels symmetrically per the platform OEM memory population rules, and verify BIOS/UEFI support for DDR5-4800 at the installed CPU; data rate may derate at higher DIMM populations.

Typische Anwendungen
MTC20F2085S1RC48BR ist geeignet für 6 Anwendungs: General-Purpose Server Memory, Edge Compute Nodes, Virtualization Hosts (Low-to-Moderate VM Density), OEM Server Builds (Dell PowerEdge / HPE ProLiant), Memory Upgrades and Fleet Refresh, Data Center Storage and Compute Appliances.
General-Purpose Server Memory
The MTC20F2085S1RC48BR's 32GB DDR5-4800 capacity with 2Rx8 organization is optimized for general-purpose server workloads. At 4800 MT/s with CL40 latency, it delivers PC5-38400-class bandwidth that keeps database, web, and file services responsive. In an 8-channel Xeon Scalable platform, eight of these modules provide 256GB per CPU at full channel bandwidth. Deployed in matched sets per the OEM population rules, the dual-rank design improves rank interleaving for better sustained throughput. Its 1.1V operation reduces module power versus DDR4, easing thermal design in dense 1U/2U chassis with on-module PMIC regulation.
Empfohlen
Edge Compute Nodes
Edge compute appliances benefit from the MTC20F2085S1RC48BR's balance of density and efficiency. According to Corewave Labs, this module is explicitly designed for edge compute use, where space and power budgets are constrained. The 1.1V DDR5 interface with on-module PMIC reduces per-module power draw, lowering heat rejection requirements in passively cooled or conduction-cooled edge enclosures. The 32GB dual-rank capacity supports local caching, inferencing buffers, and container runtimes at DDR5-4800 speeds. Registered ECC signaling protects against single-bit errors that could silently corrupt edge analytics output over long unattended service intervals.
Empfohlen
Virtualization Hosts (Low-to-Moderate VM Density)
For virtualization hosts running low-to-moderate VM density, the MTC20F2085S1RC48BR provides 32GB increments that let administrators size memory pools economically. On-DIMM ECC corrects single-bit errors that would otherwise crash hypervisors or corrupt VM images, while DDR5-4800 bandwidth supports multiple concurrent guest workloads. Populating all channels with matched 32GB modules on a Sapphire Rapids-class Xeon maximizes memory bandwidth per vCPU allocation. The dual-rank 2Rx8 topology improves controller scheduling efficiency compared to single-rank modules of the same capacity, delivering measurable gains in multi-VM benchmark throughput at 4800 MT/s.
Empfohlen
OEM Server Builds (Dell PowerEdge / HPE ProLiant)
The MTC20F2085S1RC48BR fits validated memory lists of major OEM server platforms including Dell PowerEdge and HPE ProLiant systems with Intel Xeon Scalable processors, per the NEMIX compatibility cross-reference for this exact part number. OEM integrators value Micron's DID-agnostic SKU policy, which lets Micron substitute in-stock compatible server memory to shorten lead times without changing qualified specifications. Standardizing on this 32GB DDR5-4800 2Rx8 1.1V CL40 RDIMM across a fleet simplifies sparing, RMA handling, and BIOS memory-configuration validation while maintaining full ECC registered signaling required by server memory controllers.
Empfohlen
Memory Upgrades and Fleet Refresh
For upgrading existing DDR5-generation servers, the MTC20F2085S1RC48BR is a recognized exact-match upgrade path: OWC and NEMIX both market 32GB DDR5-4800 2Rx8 288-pin 1.1V CL40 ECC RDIMMs specifically as replacements for this Micron part in Sapphire Rapids, Xeon Scalable, PowerEdge, and ProLiant systems. Its 32GB capacity lets technicians scale memory per chassis incrementally rather than replacing entire kits. Because DDR5 modules are keyed differently from DDR4, insertion is mechanically foolproof, and registered-ECC signaling ensures the upgrade is recognized at full capacity and rated speed by the server memory controller on first boot.
Empfohlen
Data Center Storage and Compute Appliances
Storage controllers and hyperconverged appliances require reliable, high-bandwidth memory for write caches, metadata, and deduplication tables. The MTC20F2085S1RC48BR's 32GB dual-rank DDR5-4800 configuration supplies the sustained bandwidth these data paths demand, while on-module ECC prevents silent bit errors from corrupting parity or index structures. Its 1.1V rail and on-module PMIC simplify power-plane design in appliance backplanes. In clustered storage nodes, matched 32GB RDIMM populations keep NUMA memory bandwidth symmetric across sockets, avoiding cross-socket traffic penalties. Registered operation supports the high module counts typical of 2U4N storage platforms.

Wichtigste Unterscheidungsmerkmale
- Genuine Micron server DRAM with DID-agnostic supply flexibility (vs. OWC 32GB DDR5-4800 RDIMM)
- Lower power per module (vs. DDR4-3200 RDIMM equivalents)
- Cost-efficient 32GB granularity for channel-matched population (vs. 64GB DDR5 RDIMM equivalents)
Designhinweise
Never mix this RDIMM with UDIMM or LRDIMM modules in the same channel, and never attempt installation in desktop DDR4/DDR5 UDIMM slots - the registered signaling and ECC protocol require a server memory controller, and OWC's compatibility documentation for this part explicitly warns it will not work in standard desktop computers. DDR5's 288-pin keyed notch is positioned differently from DDR4, preventing accidental cross-generation insertion, but verify platform DDR5-4800 support in the CPU memory controller before purchase.
Follow the server OEM memory population rules exactly: install modules in matched sets (same capacity, rank, and data rate) across channels starting with the channel farthest from the CPU. Unbalanced populations derate the bus speed below DDR5-4800 or disable channels entirely. Because DDR5 moves power conversion onto the module via a PMIC, ensure BIOS/UEFI firmware includes the latest PMIC training updates; first-boot memory training at 4800 MT/s takes longer than DDR4 and should not be interrupted.
DDR5 RDIMMs at 4800 MT/s in dual-rank configuration generate meaningful heat in dense chassis. Verify chassis airflow meets the OEM's memory thermal specification, especially when populating all eight channels per CPU. Estimated: eight modules at roughly 4-6 W each add 32-48 W of memory heat load per socket area in a fully populated 1U server - confirm chassis fan curves account for this. Micron publishes module thermal specifications in its RDIMM documentation for derating above standard ambient conditions.
The MTC20F2085S1RC48BR operates at 1.1V VDD with an on-module PMIC converting the platform 12V (or 5V auxiliary) supply. Compared to DDR4 RDIMMs at 1.2V, DDR5 lowers DRAM core power while shifting regulation onto the module. Estimated: at PC5-38400 bandwidth class and dual-rank loading, plan server PSU headroom for approximately 5 W per module during full-bandwidth memory stress testing. Avoid mixing modules from different vendors in the same channel unless both appear on the platform's validated memory list.
