The SK hynix HMA451R7AFR8N-UH is a 4GB DDR4-2400 registered ECC memory module sourced for B2B distribution to enterprise server, workstation, and storage platforms operating continuous 24/7 workloads. For resellers and system integrators, this SKU addresses demand for DDR4-generation replacement and expansion RDIMMs, including virtualization hosts and storage/cache tiers where error-correcting memory is mandatory. As a registered module it is not compatible with desktop UDIMM or DDR5 memory — we recommend verifying the target platform’s DIMM type before placing a purchase order.

Sourcing & Supply Notes
- Stock is held in volume for recurring B2B orders; single-date-code batch consistency is available for projects requiring homogeneous module populations. Contact us before ordering to confirm current stock and batch availability.
- All units ship with a standard reseller warranty and a structured RMA process; faulty returns are screened and replaced or credited within the agreed RMA window.
- Products are CE, FCC and RoHS certified, supporting compliant import and resale in most overseas markets. Export documentation can be provided on request.
- Compatibility: RDIMMs must not be mixed with desktop UDIMMs or DDR5 modules. Integrators should verify platform support for DDR4-2400 registered memory and follow vendor channel population guidelines for single-rank modules.
- For fleet expansion and channel balancing, we advise matching part number and rank configuration across mixed-module deployments; batch consistency can be specified for volume orders.
- As an entry-capacity module within SK hynix’s DDR4 RDIMM lineup, this 4GB single-rank unit is commonly ordered to fill spare slots and complete channel population in hosts where higher capacities are not required.
Wholesale & Procurement Notes
- MOQ is negotiable depending on stock position and order frequency.
- Tiered volume pricing is available — request a wholesale quote with your target quantity and required date codes.
- Typical lead time: 3–7 business days for in-stock items; larger consolidated orders quoted individually.
- Packing & shipping: anti-static trays or bulk box packing, with DHL/FedEx/UPS air freight and sea freight options for full-pallet volumes.
- RMA window: 30 days DOA inspection period plus 12-month warranty coverage on all modules.
