I don´t have the same mobo(bios), to me the settings look fine. If you decide to oc higher you'll probably need to up the voltages a bit when it becomes unstable. Just go slow and watch your temps, 70-80C seems to be the sweetspot.
Well, we can't exactly help you with the actual overclock, since every CPU is different. But your voltages look totally fine and there seems to be quite a bit of potential left in your CPU. Just make sure that everything is stable, your temperatures are fine and you don't push it too far. For daily use (and on an air cooler) I definitely wouldn't go further than 1.250V on the core, and temps should be <75°C.
Not going to run XMP or overclock the RAM?. Looks like you are sitting at default JEDEC timings and using the onboard video. If you are happy with your current CPU overclock you can try the xmp settings, bench it, and maybe see how high that RAM can go before subtimings get too sloppy.
