not enough power on the +3.3v line - Page 2

1. Search a ATX power plug layout on google.
2. Check which 2 you have to wire to turn on your PSU without a mobo.
3. Check which 2 are responsible for 3.3v

Or search a solder point to measure 3.3v on an epox 8rda+, but that's goign to be hard to find.

that would be strange, because 2 different PSU's give 2.608 v on the 3.3 line,

but I've checked the voltages with the program of Epox and there is the Vdimm 2.6** so I think MBM gives wrong results. I've didn't find any sensor for the 3.3 v-rail

but now the pc is runing outside the case for almost 2 hours without lockups, the different stresstests went fine where otherwise the pc would crash

pc is running fine now, we took everything out the case and of the motherboard, even the cpu had to leave his socket. We build the pc back up again and with succes because now the lock-ups are gone.
