The SK hynix HMAA4GR7CJR8N-XN is a 32GB DDR4-3200 ECC registered DIMM stocked for volume supply to resellers, system integrators, and IT procurement teams building or maintaining server, data center, virtualization, and database platforms. Because it is an RDIMM, address and control signals are buffered, allowing higher module counts per channel — the typical requirement for dense virtualization hosts and multi-socket server builds. Procurement teams should confirm target platforms are DDR4-based: DDR4 and DDR5 modules are not interchangeable and cannot be mixed within the same system.

Sourcing & Integration Guidance for B2B Buyers
- Batch consistency: Orders are fulfilled from the same production batch wherever stock permits. For multi-node deployments or phased rollouts, batch-matched supply can be arranged — please specify this requirement when ordering.
- Compatibility validation: This module requires an ECC RDIMM slot on a DDR4 platform and cannot be combined with UDIMMs, LRDIMMs, or DDR5 memory in the same system. Integrators should validate against the CPU vendor’s qualified memory list (QVL) before committing large orders; sample units are available for pre-deployment testing.
- Rank-balanced configurations: The dual-rank 2Rx8 layout provides a strong balance of density and per-channel performance. For fleet builds, keeping rank configuration uniform across channels helps deliver consistent memory bandwidth in multi-channel servers.
- Warranty & RMA: Units are covered by a supplier-backed warranty with a structured RMA process for DOA and failure returns. RMA authorization numbers are issued for qualifying claims, with replacement or credit options depending on stock position.
- Export & compliance: Shipments are prepared for international freight with CE/FCC/RoHS documentation available on request, supporting customs clearance and resale compliance in destination markets.
Whether you are a value-added reseller stocking DDR4 RDIMM inventory, a system integrator provisioning rack-scale builds, or an IT department sourcing standardized memory across sites, this module is held in wholesale-ready volume with ongoing restocking. For current availability, batch details, and pricing at your order volume, request a wholesale quote and our sales team will respond with a tailored offer.
