24 volts supplied to a 12 volt rail
24 volts supplied to a 12 volt rail
Sure, I can help with that. The issue you're seeing is likely related to the voltage regulation on your 24.480 output rail. Check the regulator settings or consider using a better voltage reference to stabilize it.
Everywhere bios, AIDA64, etc., people often focus on the motherboard...
If every system indicates 24v, consider checking a 12v supply and its output. It seems the motherboard might be faulty.
