Too Long; Didn't Read
Error correction code memory (ECC memory) is a type of computer data storage technique. It identifies and fixes the most common errors which could otherwise lead to data corruption or system crashes. ECC RAM is usually used in servers or graphics workstations. It is more expensive than ordinary memory sticks because of its higher tech and larger capacity. The ECC memory is equipped with ECC error checking technology. It also reduces data corruption and reduces the probability of downtime/blue screen problems. The standard configuration on home computers is 4~8GB of memory.
