Hey guys, just wondering how far you can SAFELY take this thing:

4x4 gb corsair vengeance ram
AsRock Fatal1ty Z77-Professional-M mobo
Corsair h100 water cooling
1200 watt coolermaster silent gold pro thingymajiggy (can't remember)
decent space so air is no isssue
just want to know all the steps for the bios overclock with the RAM and CPU, just some safe overclocks.
I saw some people OC'ing to 4.6 Ghz. I'd like to get mine to that point, can you guys let me know how?
and if i can overclock my ram, I'd like to get it to 2033Mhz. Can you guys lemme know how I can do that as well?
Thanks a lot guys
