Rebooting my "pile of junk motherboard" to see the AUTO problem and brb.
Ok. I guess your Hero BIOS is in Easy Mode.
Does the BIOS look like this?

If so, please press F7 to go to advanced mode, where you can find all the settings you need.
If you are in Advanced Mode, when you go to your DRAM Voltage setting and press + on your numpad, what happens?
Let me know.
