ECC memory is Error-Correcting Code memory. All RAM will experience occasional errors due to factors such as: • Cosmic rays • Alpha particles • RF interference • Power fluctuations • Static electricity discharges • Faulty components • Improper system timing ECC memory is capable of detecting and correcting some of these errors. ECC memory will correct a single failed bit in a 64-bit memory block. If multiple bits within one 64-bit memory block fail, ECC memory will detect the errors but will be unable to correct them. ECC memory is highly recommended for server-class systems. It is optional for gaming systems. ECC Requirements To use ECC memory: • The system must have all ECC memory - no mixing and matching • ECC memory must be supported by the motherboard • ECC checking must be enabled in the system BIOS
