you won't even need a guide.
go into bios, set cpu pll overvoltage to "enabled"
Make your ram 1333mhz for now (usually @ 1.5v or 1.65v, whatever your stick supports)
put the multiplier to 45, cpu voltage to 1.300v to 1.350v (id start with the higher one) (!You might be unlucky and need up to 1.4v)
make sure your LLC or Calibration is set to Ultra High, 75%, or Level 1 (asrock boards)
Vcore should be on fixed/manual, once you test prime and everything is stable, you should look toward getting the setup to become offset instead.http://www.asusrog.com/forums/showthread.php?2162-Overclocking-Using-Offset-Mode-for-CPU-Core-Voltage
My thoughts: I don't suggest going over 4.5-4.8Ghz. Anything more doesn't help FPS, only kills your cpu and produce more heat.
