I do have the i5 3570k
also sometimes my keyboard doesn't seem to work in bios (sometimes it does). Keyboard is powered on and lit.
(had to press delete to enter bios first of all so nothing wrong with my keyboard)
I have a feeling it has something to do with the bios.
I updated over network in bios a few days after I got the mobo. Running latest bios.
I'm guessing you are using a usb keyboard. Does this happen with a ps2?

Is the OC Formula designed for this? Or, should I choose either the 4-pin or the 8-pin but not both?
Thanks in advance.
All you need is the 8 pin 12v plugged in. The 4 pin is only for extra 12v for the cpu if you overclock over 5Ghz range. (liquid nitrogen)

Do I have to raise some voltage?
Did you flash to the latest bios? (dec) Did you select XMP? If so timings/clock/volts has to be set manually to achieve 2.4Ghz. I would try one stick first then if that doesn't work maybe try a different dimm but make sure you have the latest bios.
