The MTC40F2046S1RC48BA1 is a 64GB DDR5 ECC registered DIMM rated at 4800 MT/s, positioned in our catalog as a stock item for resellers, system integrators, and IT procurement teams supplying enterprise server, virtualization, and cloud infrastructure projects. Built to the JEDEC DDR5 standard as an RDIMM, it is the right fit for capacity-dense host and cache-tier configurations where registered modules are a platform requirement. Buyers should verify memory generation compatibility and the target server’s qualified vendor list (QVL) before committing to volume orders.

Sourcing & Deployment Guidance
- This is a registered DDR5 module: it installs only in platforms supporting RDIMMs and cannot be combined with UDIMM, LRDIMM, or DDR4 modules. Per-channel population limits and mixing rules follow the server vendor’s memory configuration guide — recommend your customers consult it during system planning.
- Within Micron’s DDR5 RDIMM lineup, this SKU is the dual-rank (2Rx4) 64GB build based on 16Gb DRAM, delivering greater capacity per module than single-rank 32GB-class units while staying in the standard 4800 MT/s CL40 speed bin.
- For virtualization and cache-tier deployments, we advise ordering in matched sets (identical capacity, rank, and speed grade) with even channel population so memory sustains its rated 38.4 GB/s bandwidth without downclocking. We can allocate same-batch stock for set orders to guarantee configuration consistency across your shipment.
- Units ship with manufacturer warranty; our RMA channel handles replacement or credit under standard B2B terms. All stock is CE, FCC, and RoHS compliant and cleared for export to supported destinations.
- Current availability is confirmed at quotation; larger volumes may carry a short allocation lead time depending on batch scheduling.
Wholesale & Procurement Notes
- MOQ is negotiable — trial and pilot quantities available for qualified buyers.
- Tiered volume pricing applies; request a wholesale quote for project-sized quantities.
- Typical lead time: 3–7 business days for in-stock volume; extended allocation quoted per order.
- Packing options include anti-static bulk trays, retail-boxed, or OEM-neutral packaging; consolidated air or sea freight shipping available.
- RMA window: 12 months from invoice date, replacement or credit at our discretion per B2B terms.
