Hi and welcome to Tom's forum.
Good rig you have there. I have some question before start to overclock.
1- What cooler do you have? because I can't no see one.
2- Download and use HWMonitor to know your temps, that is basic when you overclock.
3- We also need stress test programs to test the stability of overclock, so, download prime95, Linx, OCCT or y-cruncher.
