Microprocessor Voltage ( J 5K1)
This jumper block changes the output of the on-board voltage regulator. Pins 1-2 should be
jumpered for processors that require standard voltage regulation. Pins 2-3 should be
jumpered for processors that require the VRE specification. This jumper should not be
changed by the user unless changing to a new processor type. Some upgrade processors may
require a different setting. Check the processor's documentation for the correct setting.
(Standard = 3.135-3.63V, VR = 3.3-3.465V, VRE = 3.465-3.63V)
