The Samsung M393A2K43BB1-CRC is a 16GB DDR4-2400 registered ECC module stocked specifically for B2B channel customers — resellers, system integrators, and IT procurement teams building or maintaining server fleets. Supplied in consistent batches from the same production runs wherever possible, these modules simplify memory matching across multi-unit deployments and repeat orders. Buyers should note that RDIMMs are platform-specific: DDR4 registered modules are not compatible with DDR5 systems or unbuffered desktop memory, so we recommend confirming your platform’s qualified memory list before placing volume orders.

Stock & Supply
We maintain ongoing availability of this SKU for wholesale channels, with batch consistency prioritized for multi-node rollouts and service contracts. All shipments are accompanied by standard export documentation, and the product carries CE, FCC, and RoHS compliance for international distribution. Warranty coverage and RMA processing are handled through our B2B support desk with clearly defined turnaround windows, so integrators can pass through after-sales support to their own end customers without friction.
Sourcing Guidance for Integrators
- Compatibility screening: registered DDR4 modules cannot be mixed with UDIMMs or LRDIMMs; verify the server QVL and keep speed grades uniform across populated channels to prevent BIOS downclocking.
- Deployment fit: as a mainstream 2400 MT/s RDIMM, this module is a dependable choice for virtualization hosts, caching tiers, and storage arrays where ECC reliability outweighs peak bandwidth requirements.
- Channel consistency: for multi-channel configurations, order identical capacity, rank configuration (2Rx8), and speed grade to keep memory channels balanced — our sales team flags single-batch availability for larger requests.
