Ecc memory errors
WebJun 11, 2024 · Any memory error which could be corrected by the ECC is known as a correctable error (CECC). The memory errors which could not be corrected by the ECC is known as uncorrectable error (UECC).

Ecc memory errors
Did you know?
Error correction code memory (ECC memory) is a type of computer data storage that uses an error correction code (ECC) to detect and correct n-bit data corruption which occurs in memory. ECC memory is used in most computers where data corruption cannot be tolerated, like industrial control applications, critical databases, and infrastructural memory caches. WebOct 21, 2016 · Another popular way to find out, if ECC is working, was to issue the dmidecode -t memory command and read out the Total Width and Data Width. My results were 128 Bits and 64 Bits respectively. One part of the output showed details about the memory array which had a key-value pair of Error Correction Type: Single-bit ECC.
