I've got a v1.1 here that was fine then would freeze up after a few hours, but now it's worse and does it after a few minutes (5 - 10 normally).
If I'm FTPing to it (like I am now) then the screen (menus / disk space etc) freezes but the FTP keeps going for another 10 minutes or so after the menus freeze and then the FTP eventually dies as well.
Temps wer a little high so i put a heatsink on the MCPX and a big fan on the CPU / GPU to make sure, but it is still the same.
The only thing I can find is that it has 1.62v on the LPC pin 1. What would be causing the volts there please?
