Thanks Cloasters and Dimmreaper for the welcome and support!

I had done the 'How To' for the Iwill P4R533-N with Vcore and Vrimm. That was easy because the same two regulators were already being used on the KR7A, which were already described in other forums.

Dimmreaper mentioned those twin IC that control the Vcore current and I believe he is right on target. Here is what it says about those devices from the company PDF:

"Multiphase power conversion is a marked departue from earlier single phase converter configuration previously employed to satisfy the increasing current demands of modern microprocessors. Multi-phase converters, by distributing the power and load current results in SMALLER and LOWER cost transistors with FEWER input and output capacitors. These reductions accrue from higher effective conversion frequency with highr frequency ripple current due to the phase interleaving process of this topology."
I would bet those smaller and lower costs transistors along with fewer input/output capacitors did the damage to Asus's fine reputation. They got talked into trying to save money and ended with a severe current problem for the CPU.
