Add 32 GB of registered ECC memory to a compatible DDR5 server platform with this DDR5-4800 RDIMM. Registered DIMMs are intended for systems that support buffered server memory, rather than desktop-class unbuffered DIMMs. Its 4,800 MHz memory speed aligns the module with DDR5-4800 memory channels where capacity expansion and error-correcting memory are required. ECC memory detects and corrects certain memory errors during operation, while the RDIMM design registers memory control signals to support server-class memory architectures. The 2Rx8 organization identifies a dual-rank module built with x8 DRAM devices. These characteristics matter when matching installed memory to platform population rules, required DIMM type, and supported memory generation. ACCORTEC 4X77A81440-ACC combines 32 GB capacity, DDR5 technology, ECC operation, registered DIMM construction, and a 2Rx8 layout in one module. It is distinguished from non-ECC, unbuffered, and earlier-generation memory by its DDR5 ECC RDIMM specification. Match the installed host to DDR5 RDIMM support before adding the module, and maintain the platform's prescribed channel and population arrangement when planning memory expansion.
