Lenovo 4X77A08635 64GB DDR4-3200MHz RDIMM 2Rx4 CL22 Memory

Product Description

The Lenovo 4X77A08635 is a high-capacity 64GB DDR4 memory module designed for enterprise-grade servers and workstations. Operating at a rapid speed of 3200MHz, this module offers substantial bandwidth to support demanding applications, large datasets, and complex virtualized environments. DDR4 technology provides significant performance improvements over previous generations, including higher data rates and increased power efficiency. This module is a Registered DIMM (RDIMM), which includes an onboard register chip. This register buffers command and address signals, reducing the electrical load on the memory controller. This allows for higher memory densities and greater stability, making RDIMMs a standard choice for servers and high-end workstations. The 2Rx4 rank configuration indicates that the module is dual-ranked, with each rank having an x4 data organization. Dual-rank modules can offer performance benefits by providing more memory banks for the controller to access. The CAS latency is CL22, which specifies the number of clock cycles required to access a specific memory column. This, combined with the 3200MHz speed, provides a strong balance of performance for enterprise workloads. The module operates at a standard DDR4 voltage of 1.2V. Crucially, it features ECC (Error-Correcting Code) functionality, which detects and corrects single-bit memory errors, ensuring data integrity and system reliability – a critical requirement for mission-critical server applications. The 4X77A08635 is an excellent choice for upgrading Lenovo systems that require high-performance, high-capacity, and reliable memory.
