... and the numbers that come out of this may have no relation to your motherboard labels at all. What do you do then? Read schemantics again? Or do binary search on the DIMM again like Eric suggested?
For all of this a system specific mapping table is needed and the only place to get this as a default option without explicit configuration for each motherboard is the BIOS.
