The SK hynix HMA41GR7AFR8N-UH is an 8GB DDR4-2400 registered ECC DIMM sourced for B2B channels, targeting resellers, system integrators, and IT procurement teams servicing enterprise server fleets, workstation builds, and storage deployments. This part number is a high-volume service component for maintaining DDR4-generation platforms — virtualization hosts, storage controllers, and general-purpose rack servers — where data integrity and 24/7 uptime are contractual requirements. As a registered ECC module, it is not interchangeable with unbuffered desktop memory or DDR5 platforms; we recommend buyers confirm platform compatibility across their installed base before placing volume orders.

Supply & Sourcing Information
Stock is held in volume with consistent batch/date-code matching available for orders requiring homogeneous lots — a key consideration for system integrators building multi-node configurations and for service organizations needing field-replaceable units identical to deployed stock. Mixed-batch shipments can be flagged and filtered on request prior to dispatch.
All shipments leave with export-compliant documentation, and modules carry CE, FCC, and RoHS conformity appropriate for distribution in major overseas markets. Standard warranty coverage applies to every unit, with a structured RMA process: faulty returns are assigned an RMA number, tested at our facility, and replaced or credited within the agreed window, minimizing downtime for your downstream customers.
Lead times for stocked quantities are typically short, with same-week dispatch on most orders; larger allocations or scheduled deliveries can be arranged against a framework agreement. Whether you are a reseller stocking this as a recurring service SKU or an integrator fulfilling a server build-out, our sales team can align packing, labeling, and delivery schedules to your project timeline.
Good to know for integrators and resellers
- RDIMMs must not be mixed with UDIMMs, LRDIMMs, or DDR5 modules in the same system; all populated slots should carry the same memory type, and channel population should follow the server vendor’s slot-order guidance — worth communicating in your own customer documentation.
- The 2Rx8 dual-rank 8GB configuration is one of the most frequently requested density points for memory channel population in virtualization hosts and cache/tiered storage nodes, making it a dependable repeat-purchase SKU; higher-capacity RDIMMs are also available for volume buyers.
- Advise end customers to confirm that their motherboard or server model explicitly supports DDR4-2400 ECC RDIMM, since the same physical form factor is not accepted by desktop or DDR5-era platforms — this reduces RMA volume from compatibility mismatches.
Wholesale & Procurement Notes
- MOQ negotiable depending on stock position and destination market.
- Tiered volume pricing available — request a wholesale quote for current pricing on your target quantity.
- Typical lead time: 3–7 business days for stocked quantities; scheduled deliveries negotiable.
- Packing & shipping: anti-static trays/boxes, bulk cartons, or custom-labeled packaging; air or sea freight options with full export documentation.
- RMA window: standard warranty period with structured RMA handling for tested replacements or credit.
