MTC20C2085S1EC56BR Übersicht
A DRAM module (sometimes called a memory module, DIMM, or SDRAM module) is a printed-circuit board that aggregates multiple DRAM devices into a single, addressable unit accessed through a parallel data bus. In the system hierarchy, a DIMM sits beneath the memory controller, above the individual DRAM die, and is governed by the JEDEC DDR5 standard for electrical, timing, and command-protocol compliance. UDIMM stands for Unbuffered DIMM, meaning the address and control signals from the host memory controller reach the DRAM devices directly without an intermediate register, trading some signal-integrity margin for lower latency and lower cost relative to RDIMM.
Key features of the MTC20C2085S1EC56BR include on-module ECC for single-bit error correction and multi-bit error detection, integrated PMIC (power management IC) support that brings 5 V from the slot and generates all required DDR5 rails on-module, dual-rank organization (2R) that boosts per-channel capacity, and JEDEC-standard 1.1 V operation. The module is rated at DDR5-5600 PC5-44800 with a CL46 timing and 2Rx8 rank/x8-device configuration.
Technically, the module aggregates multiple 16 Gb DDR5 devices to reach 32 GB, with on-board SPD/EEPROM storing the JEDEC Serial Presence Detect configuration so the host BIOS recognizes speed, timing, voltage, and organization at POST. The on-module PMIC handles voltage regulation, while the on-die ECC engine and ECC scrubbing protect against bit errors common in dense server-class workloads.
Typical applications include edge-compute servers, low-VM-density virtualization hosts, SMB and branch-office servers, AMD EPYC Genoa / Threadripper PRO workstations (TRX50/WRX90 platforms), and Intel Xeon W-2500 entry workstations that specify ECC UDIMM. The module is also used in general-purpose entry servers and content-creation workstations where 32 GB of ECC-protected DDR5-5600 memory is appropriate.
When designing with this module, confirm the host board's QVL (qualified vendor list) lists 32 GB 2Rx8 DDR5-5600 ECC UDIMM support, and ensure the memory controller supports 5600 MT/s (some platforms fall back to 4800 MT/s or 5200 MT/s when a faster module is populated). Mixing 2Rx8 and 1Rx8 modules in the same channel can force speed derating; identical rank organization per channel is recommended.

Typische Anwendungen
MTC20C2085S1EC56BR ist geeignet für 6 Anwendungs: Edge-Compute Servers, SMB / Branch-Office Servers, AMD Threadripper PRO Workstations, Intel Xeon W-2500 Workstations, Low-VM-Density Virtualization Hosts, General-Purpose Entry Servers.
Edge-Compute Servers
The MTC20C2085S1EC56BR fits edge-compute servers because its 32 GB capacity per module lets designers populate 4 to 8 DIMM slots for 128 GB to 256 GB of total memory without the cost premium of RDIMM. The 5600 MT/s speed sustains real-time analytics on streaming telemetry, while on-module ECC protects against soft errors common in thermally constrained edge cabinets. Compared with LRDIMM, the unbuffered design reduces latency by one clock and removes the buffer's power draw, important at remote sites with limited cooling. Place the module in slots following the motherboard's population order to maintain 1DPC signaling for full DDR5-5600 operation; using 2DPC may force a speed derate.
Empfohlen
SMB / Branch-Office Servers
The MTC20C2085S1EC56BR is ideal for SMB and branch-office servers that need enterprise-grade reliability without RDIMM expense. Its 2Rx8 dual-rank organization supplies the bandwidth a single-socket Xeon E or EPYC 4004 needs to run file/print, light virtualization, and small database workloads at full speed. The 1.1 V DDR5 rail (down from DDR4's 1.2 V) cuts module power roughly 20%, helping meet small-form-factor PSU and thermal budgets. Install in matched pairs across the two memory channels to enable the platform's full 2-channel bandwidth; mismatched ranks can force speed derates on some controllers.
Empfohlen
AMD Threadripper PRO Workstations
The MTC20C2085S1EC56BR is verified compatible with AMD Threadripper PRO (sTR5 / TRX50 / WRX90) platforms, where 32 GB DDR5-5600 ECC UDIMMs balance capacity, speed, and cost for content-creation workstations. The 2Rx8 organization delivers the bandwidth CAD, video editing, and simulation workloads demand, while ECC protects long-running renders from silent data corruption. The module runs at the platform's native 5600 MT/s in 1DPC across the 4-channel memory subsystem; populating all 8 slots with this module reaches 256 GB at full speed. For 512 GB configurations, pair two MTC20C2085S1EC56BR modules per channel in matched rank pairs.
Empfohlen
Intel Xeon W-2500 Workstations
The MTC20C2085S1EC56BR pairs naturally with Intel Xeon W-2500 series (W7, W5, W3) workstations that require ECC memory for professional CAD, simulation, and AI-inference workloads. Its 5600 MT/s rating matches Xeon W-2500's native 1DPC speed, ensuring the memory controller does not derate when this module is populated. The on-module PMIC and ECC engine align with workstation firmware expectations, eliminating the POST validation issues that plague consumer-grade UDIMMs on Xeon platforms. Use four modules for 128 GB across 4 channels; use eight modules in matched pairs for 256 GB at full speed.
Empfohlen
Low-VM-Density Virtualization Hosts
The MTC20C2085S1EC56BR fits low-VM-density virtualization hosts running 4 to 12 VMs per host, where 32 GB per DIMM lets operators size memory to VM count without the cost of higher-density RDIMMs. The 2Rx8 organization sustains the random-read/write pattern typical of mixed VM workloads, while ECC scrubs the single-bit errors that would otherwise crash guest VMs. The DDR5-5600 speed boosts memory-bound operations like in-memory caching and JIT compilation. Populate channels symmetrically - one module per channel, then add a second matched module per channel if VM density grows - to maintain the platform's rated bandwidth.
Empfohlen
General-Purpose Entry Servers
The MTC20C2085S1EC56BR serves general-purpose entry-server roles including file/print, light database, mail, and small virtualization workloads where ECC UDIMM is sufficient and RDIMM cost is hard to justify. The 32 GB density supports 64 GB to 128 GB populated configurations in a typical 4-slot or 8-slot system, while the 1.1 V DDR5 rail keeps total system power in check versus DDR4-based servers of similar capability. The JEDEC-standard SPD allows BIOS to auto-configure speed and timing, reducing deployment time across a fleet. For mixed-vendor fleets, pair this module with cross-brand equivalents like the Samsung M391A4G43BB1-CWE to simplify spares logistics.

Designhinweise
Do not mix 2Rx8 modules (like the MTC20C2085S1EC56BR) with 1Rx8 modules in the same channel - most platforms derate speed when ranks are mismatched. Do not populate a UDIMM slot into a server that only supports RDIMM; the key notch position differs between UDIMM and RDIMM, so physical insertion is blocked. Verify the host board's QVL lists 32 GB 2Rx8 DDR5-5600 ECC UDIMM before deployment, as some consumer DDR5 boards disable ECC validation in firmware even when the physical slot accepts ECC modules.
Estimated: at 1.1 V and DDR5-5600, a 32 GB 2Rx8 module typically draws 4-6 W active and 1-2 W idle, depending on the workload. With 8 modules in a populated 2U server, total memory power can reach 30-50 W, contributing meaningfully to chassis thermal load. Ensure inlet air stays below 35 C and provide at least 200 LFM airflow across the DIMM bank to keep the on-module thermal sensor below the 95 C JEDEC threshold. Modules with on-module PMIC concentrate heat near the SPD/PMIC area; verify the chassis airflow pattern passes through the DIMM slots rather than short-circuiting above them.
The MTC20C2085S1EC56BR follows JEDEC DDR5 UDIMM pinout (288-pin, 1.1 V key) and is electrically interchangeable with any JEDEC-compliant 288-pin DDR5 ECC UDIMM. When upgrading existing systems, confirm the motherboard BIOS supports the module's SPD profile - some older BIOS revisions predate DDR5-5600 support and may boot at DDR5-4800 or fail to POST. Update BIOS before deployment for full speed. For multi-DIMM-per-channel configurations (rare on UDIMM platforms), use identical rank, speed, capacity, and vendor in each channel to avoid the controller's speed derate.
