If you have a spare known-good ECC DIMM, you can convert it to a known-
faulty DIMM by cutting a single I/O lead on one of the RAM chips.  If
you pick a chip where you can read the part number, you should be able
to download a datasheet (including pinouts) from the chip manufacturer.
You might also be able to cut an I/O track on the DIMM itself.
