Gigabyte GA-X79-UD3 LGA 2011 Motherboard Review

Today we will be taking our first step with both feet into Intel's latest X79 LGA 2011 platform with Gigabyte's GA-X79-UD3 consumer-level motherboard.  It's not entirely accurate to call the GA-X79-UD3 the "lowest" end of the other X79 offerings by Gigabyte, as the family has a rather mixed bag of feature sets, but it's most appealing to that statement in that it has the lowest price, and the greatest ease-of-entry into a not-so-cheap ecosystem.

Hi I have this motherboard and I have some questions.
1. Lets consider that the top edge of the motherboard is the edge close to cpu socket, and the left edge of mobo is the back panel of desktop. Then, in the top-right position of motherboard, we can see headings with 3 pins but ther is no label on it. These pins are not headings for chassis fans. What are those pins?
2. what is the bios version installed by default in this motherboard?
