The Samsung M393A4K40CB1-CRC 32GB DDR4-2400 ECC registered DIMM is a high-volume enterprise memory SKU frequently requested by resellers, system integrators, and IT procurement teams for server fleet builds, capacity expansions, and platform refresh projects. As a JEDEC-standard DDR4 RDIMM, it deploys across Intel- and AMD-based server platforms that support registered modules. Procurement note: verify the target platform’s maximum supported memory data rate before bulk ordering, since hosts rated below 2400 MT/s will down-clock this module.

Sourcing & Deployment Guidance for B2B Buyers
Stock for this SKU is held in volume and allocated in date-code-consistent batches. When placing bulk orders, we can supply single-batch, single-revision inventory on request — an important consideration for system integrators and data center operators who require uniform firmware/SPD profiles across a deployment for predictable channel performance and simplified RMA tracking. Batch and date-code documentation can be provided with shipment upon request.
All units ship as original Samsung components. Warranty coverage and RMA handling are processed through our wholesale channel: defective units reported within the RMA window are cross-shipped or credited under agreed terms, minimizing downtime for your downstream customers or internal deployments. Please retain batch numbers for warranty claims.
This module complies with CE, FCC, and RoHS requirements, with conformity documentation available to support import and export clearance in most jurisdictions. Lead times for stocked quantities are typically short; larger volume orders may be scheduled against incoming production batches. For deployment planning, note that RDIMMs are not interchangeable with DDR5 modules, UDIMMs, or LRDIMMs, and should not be mixed with LRDIMMs in the same host — always validate against the server’s qualified memory list (QVL) and population rules before committing to order quantities.
At the 2400 MT/s / PC4-19200R grade, this is an entry-tier DDR4 RDIMM well suited to legacy-generation hosts whose memory controllers cap at 2400 MT/s, making it a cost-effective line item for resellers serving the installed-base refresh and secondary market. For virtualization and database workloads, we recommend advising your customers to order in matched sets (identical capacity, rank, and speed grade) so channels can be populated symmetrically — volume orders can be split into uniform set sizes on request. To check current stock, batch availability, and volume pricing, request a wholesale quote.
