If the program your talking about is a seperate program that uses the USB interface to change timings then i think we are talking about the same thing. There is drop down menu with all the various settings you can adjust and a send button to apply (you actually have to remove power from the M4-ATX before the new setting take place).
Thats good news about the quality of the M4 and stability of the rails.
Did you ever experience wavy interference lines in your display because of the M4-ATX? or was it just RF interferance in your radio and audio?
While bringing the carpc in the house and hooking it up to a different monitor i noticed the wavey interferance lines were still present meaning it must be coming from the M4-ATX.
