Anyone have any idea what might be going on here? I ask because I'm fixing to repair a broken MSV11-J for a list member, and the combo of ECC and this might make it hard to track the problem down. (If only one chip is dead, the ECC _should_ be able to 'paper over it'. So there are probably two? But if I turn off ECC, to be able to find the bad chip, will I get deceived by this other problem?)
