In the 3rd picture down where it says Core FID thats where you change the clock rate its at x14 atm giving you 2800(it looks like) mhz Try upping that number by one until it becomes unstable or you achieve your desired clock, You only really need to adjust voltage if you cant make it stable at anything higher. Also make sure to keep track of your changes and always make small changes then test.
For more information on your chip and motherboard look to google there are sites dedicated to overclocking.
in spec you not show your cooler ! reset your oc by clear cmos
, go bios, try overclock without adding voltage ( your vcore default 1.45v), go bios set overclock at manual, increase fsb to 240, increase voltage ram at 1.6v , run ratio ram at 1333 (3:10), set voltage cpu at 1.38v- 1.4v. Let other under auto include cnq or anything ! Save your setting ... Boot
You need test by fast use intelburntest at 20X set memory at high maybe just 15minutes. See max temp that max at 60C when you ran stress test.
