MICRON MTC20F2085S1RC48BA1 32GB DDR5 4800 RDIMM
The Micron MTC20F2085S1RC48BA1 is a 32GB DDR5 ECC registered DIMM (RDIMM) running at 4800 MT/s, aimed at enterprise buyers building or expanding server platforms for virtualization hosts, cloud nodes, and cache-tier workloads. As a JEDEC-standard RDIMM, it relies on platform support for DDR5 registration and ECC, so confirm your motherboard and CPU generation before ordering. Note that DDR5 RDIMMs are not backward or forward compatible — they cannot be mixed with DDR4 or LRDIMM modules in the same channel.

Good to know
- Compatibility: This is a DDR5 registered module (288-pin, 1.1V) and will only fit DDR5 RDIMM-capable server platforms. Verify your CPU/board memory QVL and note that mixing RDIMMs with UDIMMs or LRDIMMs in the same channel is not supported.
- Family positioning: Within the DDR5 RDIMM lineup, this dual-rank (2Rx8) 32GB module balances density and channel population — dual-rank configurations can improve effective bandwidth on memory-intensive workloads versus single-rank equivalents at the same capacity.
- Buying tip: For multi-socket or high-core-count virtualization hosts, purchase matching modules in sets and populate channels symmetrically per your server vendor’s population order to achieve rated bandwidth and avoid memory-frequency downtraining.
For tray and reel pricing, current stock by part number and date code, and volume discounts on bulk orders, request a bulk quotation.
