All of the memory is low profile. However, I just noticed on the web, that only a Rev 3(C) ROM is able to accept 256RAM modules. My Rev 3 is on its way. However, I now don't even have the fan spinning. When I removed the PS and plugged it in, I tested the power supply at the 20 pin power supply connector. With the black lead of the voltmeter connected to pin 16 and red lead connected to pin 2 the meter measured 3.3VDC. I measured no other voltage with the black lead at 16 and the red lead traveling to all the other pins. Using the ohm meter I was able to get a zero ohm reading with the black lead on 16 and the red lead on the metal case of the power supply. I am beginning to believe the PS is my problem.
