Yup, still having the power issues when OC'd to 2.8GHZ. I disconnected the case fans, but still shuts down during 3DMark when operating at 2.8GHZ.
I would agree with you assessment that one of the rails is being overloaded.
It's an odd issue that occurs when I raise the CPU voltage. For example, 2.7GHZ @ 1.425v is ok, but if I raise the CPU voltage to 1.45v and keep the CPU @ 2.7GHZ, the system will shut down.
With the CPU @ 2.7GHZ /1.425v the system is stable and I can even overclock the video card to 775/875 with ease.
