Hello,
I have a strange issue on one of my SS7 motherboard - Tekram P5MVP3-A4. It is a ATX size and powered motherboard. When I was mounting the system I had inserted , a 3.3 Volt only Chinese Rage XL PCI (without voltage mod) card and an Intel Network 100Pro PCI card. After a minute of working booth of those cards where approx. 70 °C or more and were hard to touch. System boots correctly, but I shut it down immediately, because I remember that Rage XL should be, a rather cool card.
I had done some voltage measurements. There are three mosfets Voltage regulator on the board.
One of them is PHD3055E which what I understand change the 3.3V (form ATX i assume) to 4.8V and inject it directly into PCI 3.3V rail.
I had measure the voltage on Rage XL mosfet and sure it is 4.8V instead of 3.3V.... There is a connectivity in multimeter between Rage XL mosfet and the motherboard PHD3055E.

For me it looks like error in motherboard production, and i wonder how to fix it. My idea is to get rid of this PHD3055E and in its place hard wire 3.3 V from ATX connector into the former drain pad of PHD3055E.

I also wonder if this was common issue back then.

Interesting is also that: if I insert into PCI old Rage PRO PCI the card isn't even hot and it works correctly. So it is only the issue for 3.3V capable PCI cards.
