ECC (Error Control and Checking) En metod genom vilken fel på bit- eller flerbitsnivå i RAM kan upptäckas och rättas till när datan skickas till processorn.
"ECC" detects and corrects memory errors and "registered" means the memory registers delay memory information for one clock cycle to ensure all communication from the chipset is collected by the clock edge, providing a controlled delay on heavily loaded memories. Simply put, error correction code and registered memory is designed to give you the greatest stability and reliability possible. Unfortunately, this stabilizing technology also slows down the data bandwidth of the memory. This technology also makes this type of memory more expensive. Speed and price is the two big reasons you will not find this type of memory in the average home computer, but you will find it in high end work stations and servers.
