I believe starting with the Quicksilver, Apple put voltage on one of the mounting posts for the cpu module to boost the available amperage above what it could push through the existing connector. The DA doesn't supply this voltage, and could get annoyed when that voltage pickup on the cpu module is bridged to ground. The aftermarket cpu's get around this by ignoring that voltage point, and expecting to get the juice via an external molex connector I believe.
