The SK hynix HMT42GR7BFR4A-PB is a 16GB DDR3L registered ECC DIMM operating at 1600 MT/s, positioned for B2B buyers who maintain, repair, or extend DDR3-generation server fleets. Because this generation of platforms is largely past end-of-life from OEM channels, resellers and system integrators rely on wholesale sourcing to fulfill spares contracts, break-fix demand, and legacy refresh projects. Stock is held in volume with batch consistency maintained across shipments, so mixed or phased rollouts receive modules from matched date codes wherever possible. Prospective buyers should verify platform generation before ordering, as DDR3L RDIMMs are not interchangeable with DDR4 or DDR5 modules.

B2B Sourcing Notes
Every order is backed by a defined warranty period with a structured RMA process: faulty units reported within the warranty window are tested, replaced, or credited per agreed terms, minimizing downtime for your maintenance contracts. Shipments are packed in anti-static trays or bulk packaging according to order size, with export documentation prepared to meet CE, FCC, and RoHS requirements for cross-border delivery. Typical lead times are short for in-stock quantities, and larger program orders can be scheduled in staged releases to match your project timelines.
Integration and Deployment Considerations
- This RDIMM with ECC requires a server-class platform supporting registered memory; it will not function in desktop boards or alongside unbuffered DDR3 modules. Population rules regarding speed and ranks per channel depend on the memory controller.
- The dual-rank 2Rx4 configuration at PC3L-12800R delivers a balanced capacity-per-module profile, generally enabling higher total memory per channel than single-rank modules on supporting platforms — useful when standardizing configurations across a customer’s fleet.
- For system integrators: confirm the target server’s qualified memory list (QVL) for 1.35V DDR3L RDIMM support, and populate channels symmetrically with matched modules to sustain rated 1600 MT/s operation. Batch-consistent supply supports this symmetry across multi-unit deployments.
Wholesale & Procurement Notes
- MOQ negotiable — flexible minimums for trial orders and framework agreements.
- Tiered volume pricing available; contact sales to request a structured quotation.
- Typical lead time: 2–5 business days for stocked quantities; scheduled deliveries for program orders.
- Packing & shipping: anti-static trays, bulk cartons, or retail-neutral packaging; DHL/FedEx/air or sea freight with full export documentation (CE/FCC/RoHS compliant).
- RMA window: standard warranty coverage with DOA replacement and credit options for eligible returns.
