[DRAM and ECC]

If all your DRAM modules have parity chips (e.g. 8 chips + 4 parity chips), they are considered 36bits. This motherboard sums the memory per bank and therefore two modules will give 72bits and the following will be displayed:

If your DRAM modules do not have parity chips (e.g. 8 chips), they are considered 32bits and the following will be displayed instead:

The default of Disabled for Memory parity SERR# (NMI) will not show memory errors on your monitor. When using parity DRAM modules, you can select from the default of Parity or ECC (Error Checking and Correcting) to correct 1 bit memory errors that may occur in the memory. See Section III (Installation) of the baseboard user’s manual for DRAM memory modules information.
