The Micron MTC20F1045S1RC64BD2 is an enterprise-grade 32GB DDR5-6400 single-rank (1Rx4) ECC Registered DIMM engineered for next-generation data centers and enterprise workloads. Operating at a nominal 1.1V, this PC5-51200 RDIMM delivers massive bandwidth and improved power efficiency for memory-intensive computing. Built with Micron high-yield silicon, it integrates an onboard PMIC and advanced error correction to ensure maximum uptime in enterprise environments.
The MTC20F1045S1RC64BD2 is built on JEDEC DDR5 RDIMM architecture utilizing Micron 16Gb D-die DRAM components organized in a 1Rx4 configuration. The module utilizes twenty x4 DRAM packages across two independent 40-bit subchannels (32-bit data plus 8-bit ECC each) to achieve a 32GB usable capacity with full sideband error correction. A central JEDEC-compliant Registering Clock Driver (RCD) buffers command, address, and clock signals, reducing electrical load on the host processor's integrated memory controller.\n\nDDR5 moves voltage regulation directly onto the DIMM via an onboard Power Management IC (PMIC) that steps down server 12V input to 1.1V VDD/VDDQ/VPP, lowering motherboard complexity and improving power integrity. The module integrates an SPD Hub with embedded temperature sensors for telemetry. Reliability is backed by a dual-layer error mitigation scheme comprising internal on-die ECC (ODECC) for bit-flip correction within the DRAM core and end-to-end sideband ECC for host bus data protection. The part number decodes to Micron module (MTC), form factor classification (20F), capacity/organization identity (1045), single-rank RDIMM (S1RC), 6400 MT/s speed bin (64B), and D-die revision (D2).
Always verify against your server's qualified vendor list (QVL).
Yes, DDR5 memory modules are backward-compatible with lower JEDEC speeds. The module will automatically downclock to match the maximum speed supported by the host CPU memory controller and server BIOS.
No, this is an enterprise Registered DIMM (RDIMM) featuring an RCD and ECC, which is electrically incompatible with standard desktop or unbuffered (UDIMM) motherboards.
A 1Rx4 configuration places a lower electrical capacitive load on the memory channel than dual-rank modules, enabling higher operational frequencies, especially in multi-DIMM-per-channel configurations, while providing enhanced advanced ECC capabilities like Chipkill.
