function
With the function being Enable, CPU will

the ECC error initiatively. The advantage over
the common ECC function is that ECC can
only find error when reading the memory.
This function can find and correct the ECC
error in the memory without reading the
memory content; The default is [Disable]
Once this function is enabled, when CPU
reads certain memory and finds Ecc error, it
will correct it. Default is [Enable]
Once this function is enabled, within a single
rank in DIMM if a particle occurs error, the
particle is used for error correction function
will replace it, then the rank loses Device
tagging function, and
capabilities declines. Default is [Disable]
