The SK hynix HMAA4GR7AJR8N-XN is a 32GB DDR4-3200 ECC Registered DIMM positioned for volume procurement by resellers, system integrators, and IT departments outfitting enterprise server fleets, data center platforms, virtualization clusters, and storage arrays. For B2B buyers standardizing on JEDEC-compliant RDIMMs across dual-socket and multi-node deployments, this part supports batch-consistent sourcing for large channel-population projects. As with all registered DDR4, verify that target platforms accept DDR4 RDIMMs specifically — these modules cannot be mixed with UDIMMs, LRDIMMs, or DDR5 modules on the same board.

Supply & Sourcing Information
- Stock & batch consistency: Volume quantities are available from ongoing supply; modules within a single order are fulfilled from the same production batch and date code wherever possible, which simplifies validation and channel matching for integrators building multi-socket systems.
- Compatibility: RDIMMs require a registered-DIMM-capable server or workstation platform; mixing RDIMMs with UDIMMs or LRDIMMs on the same channel is not supported, and achieved data rate (3200 MT/s or lower) depends on CPU generation and channel population. Our team can assist with platform qualification questions before you commit to order volumes.
- Deployment profile: The 2Rx8 dual-rank, x8 DRAM configuration balances density and performance within SK hynix’s DDR4 RDIMM lineup, making it a reliable repeat-order SKU for virtualization hosts and storage/cache workloads where ECC reliability and sustained bandwidth are contractual requirements.
- Warranty & RMA: All units ship with a full replacement warranty. RMA requests are handled through a dedicated B2B channel with defined turnaround targets, so end-customer commitments are not disrupted by defective-unit handling.
- Export & compliance: Shipments are prepared with CE/FCC/RoHS documentation to support customs clearance and downstream compliance audits in overseas markets.
Wholesale & Procurement Notes
- MOQ: Minimum order quantity is negotiable depending on project scope and repeat-purchase potential.
- Pricing: Tiered volume discounts available — pricing improves with order size; request a quote for your target quantity.
- Lead time: Typical dispatch within 2–5 business days for stocked quantities; larger batch orders confirmed at quotation.
- Packing & shipping: Anti-static tray or bulk packaging options; supports DHL/FedEx/UPS express freight with full export documentation.
- RMA window: Standard 12-month warranty with a 30-day DOA/return window for unopened units.
