Expand your server memory ceiling to 128 GB with the SK Hynix CXL 2.0 Type-3 Memory Expansion Module, engineered for next-generation enterprise systems requiring coherent device memory at scale. This add-in card leverages the Compute Express Link 2.0 protocol to deliver host-managed device memory (HDM) with CXL.mem protocol support, enabling memory disaggregation across modern data center architectures. SK Hynix combines DDR5 DRAM technology with full ECC support to ensure reliability in mission-critical workloads where data integrity is non-negotiable.
Built on PCIe 5.0 x8 host interface architecture, the SK Hynix module (part number HMSB8GAESA041N) integrates seamlessly into systems equipped with CXL 2.0-capable CPUs and compatible firmware. Power delivery flows directly from the PCIe slot via 3.3 V and 12 V connectors, eliminating the need for auxiliary power infrastructure. IT procurement teams and infrastructure architects standardizing on Linux kernel 5.12 or later with CXL subsystem support will find this module fully compliant with both the CXL Consortium CXL 2.0 Specification and the PCIe 5.0 Base Specification. Operating across an ambient temperature range of 0°C to 55°C, it maintains stability in typical data center environments.
