Hi,
I've come across this annoying issue with my PC Chips M912 ver:1.7 motherboard. When I configure the board for 3.3V for using DX4s and 5x86 the CPUs will not work. In 5V configurations my DX/DX2 cpus work just fine. In fact, I had been using a DX4-100 processor at 5V for a while without even realizing. It just works, however when I switch to 3.3V mode it refuses to POST.
It's probably a problem with the voltage regulator. I would like to ask you guys some questions:
1) how to properly diagnose if the regulator is indeed broken
2) what part number I could use to replace this potentially broken regulator
3) any alternative idea of why I may be experiencing this issue
Thanks in advance!
