Expand memory capacity in compatible Nutanix server platforms with a 64 GB DDR5-6400 ECC registered DIMM. The Axiom Memory C-MEM-64GB-6400-X8-AX combines DDR5 signaling, error-correcting code protection, and registered buffering in a server-class RDIMM format. Its 2Rx8 organization identifies a dual-rank module built with x8 memory devices, a layout commonly used in enterprise memory configurations. This module fits memory expansion projects where host memory must support virtual machines, database buffer pools, caching layers, or other workloads that benefit from additional installed RAM. ECC memory detects and corrects certain memory errors, while the registered DIMM architecture is intended for platforms engineered to accept RDIMMs rather than unbuffered desktop memory. DDR5-6400 operation provides the module's rated data rate when installed in a compatible system configuration. The specific combination of 64 GB capacity, DDR5-6400 speed grade, ECC support, registered architecture, and 2Rx8 layout distinguishes this module within the broader DDR5 server-memory range. Confirm the target Nutanix platform supports 64 GB DDR5 ECC RDIMMs and its installed processor and memory population rules support the intended operating speed. Match the module type to the system's supported memory architecture before installation.
