The MTC40F2047S1RC56BB1 from Micron is a 128GB DDR5 ECC registered DIMM rated at 5600 MT/s, supplied through our wholesale channel for resellers, system integrators, and IT procurement teams building or refreshing DDR5 server platforms. Typical deployments include virtualization clusters, database and cache-tier nodes, AI/HPC compute, and cloud infrastructure projects that require maximum capacity per slot with full error correction. As a registered DDR5 module, it can only be used in platforms that explicitly support DDR5 RDIMMs—DDR5 and DDR4 RDIMMs are not interchangeable, so we advise buyers to confirm platform compatibility before placing volume orders.

Sourcing & Supply Information
- Stock & availability: this SKU is regularly stocked for wholesale distribution; confirmed orders ship from available inventory, and ongoing project demand can be supported with scheduled deliveries.
- Batch consistency: for multi-server builds we can supply modules from a single date code/lot where stock allows—please note batch requirements at quotation stage so we can allocate matching inventory.
- Warranty & RMA: units carry the manufacturer’s warranty handled through our RMA channel; defective returns are tested and replaced or credited per our wholesale RMA procedure.
- Lead times: in-stock quantities typically dispatch within standard processing time; larger project volumes may require confirmation of allocation and estimated delivery before order acceptance.
- Export compliance: products are supplied with CE, FCC, and RoHS conformity for export to supported markets; buyers are responsible for import compliance in the destination country.
- Suitability: ideal for IT resellers fulfilling server builds, system integrators standardizing DDR5 memory across deployments, and procurement teams seeking consistent, verifiable supply for enterprise infrastructure.
Good to know
- RDIMMs must be installed in platforms explicitly supporting DDR5 registered modules; they cannot be mixed with DDR4 RDIMMs or consumer UDIMMs, and supported speeds depend on CPU memory controller and channel population—consult your server vendor’s qualified memory list (QVL) for achievable data rates.
- With 128GB per module at 5600 MT/s, this RDIMM sits at the high-capacity end of the JEDEC DDR5 RDIMM lineup, allowing dense memory configurations in fewer slots compared to lower-capacity modules, which is useful for virtualization and in-memory cache tiers.
- Buying tip: match rank configuration (2Rx4) and speed grade (PC5-44800R) across all modules in a build to keep memory channels balanced and avoid downclocking.
