ECC Error Checking
Enable the DRAM controller to read/write ECC check-bits on the DIMMs and it
allows the north bridge to check and correct ECC errors on the DRAM bus during
normal CPU or bus master read requests.
Options: Disabled / Enabled
ECC Error Log
Enable the MCA to log or report ECC errors on the DRAM bus.
NOTE: The MCA must still be programmed according to the desired MCE outcome.
Options: Disabled / Enabled
ChipKill
Enable 4-bit ECC mode (Chipkill) on dram controllers with all x4 ECC capable
DIMMs.
Options: Disabled / Enabled
ECC Scrub Redirection

correctable error on the DRAM bus is detected during a normal CPU or bus master
read request.
Options: Disabled / Enabled
