there's only 2 settings you need to touch for a basic overclock
the multiply and the vcore
if it wont load 4.2(x42 multi) at 1.2v something isnt right
i dont think u need a new cooler to overclock at all just stay away from going over 1.3, you shouldnt need to
1.2v is good upto 4.5
and when i said about learn how to reset the bios before you start, i meant the jumpers on the board, tho some fancy boards have a button
so yeh have another go after grabbing an icepop
