Module Configuration: 2Rx4 (This means the module has two ranks, each with 4 chips.)
Speed: PC3-14900r (This indicates the module’s data transfer rate, which is approximately 1866 MHz)
Form Factor: Registered (R) (This indicates that the module is a registered DIMM, which is typically used in server environments for better stability and error correction.)
ECC: Likely to have ECC (Error-Correcting Code) support, as registered modules generally do. This helps detect and correct internal data corruption.
