commit 2f4cc7458057cd9f7f11b4b6cfc407a7fd9ed530 Author: Timothy Pearson tpearson@raptorengineeringinc.com Date: Fri Nov 20 14:51:50 2015 -0600
mainboard/asus/kgpe-d16: Update NB VDD upper voltage limit
Certain older Opteron processors use a higher (+1.2V) northbride voltage. The existing code assumed the use of +1.1V northbridge voltages and threw an alert when the older Opterons were installed.
Update the permissible NV voltage range to include both the 1.1V and 1.2V Opteron processors.
