The IBM 4GB ECC Registered DIMM Dual Rank Memory Module strives to be a dependable and stable memory option for users who have demanding workloads involving complex textures and multi-threaded environments that require a great deal of dependability from their system. This is a 4GB memory module intended for installation into servers. It possesses the ECC (Error Correcting Code) capabilities which helps in error detection and correction for ensuring data integrity through various processing stages. This module has also dual rank design which yields higher data rates than single rank modules. The IBM 4GB SRAM ECC Registered DIMM Dual Rank Memory Module has these advantages of stability answered and thus becomes the preferred memory module for dual socket server configurations.
