Asrock has some motherboards able to overclock non-K CPUs with no need of "special" BIOS. Do i recommend it? Not at all. You are overclocking a CPU "not made" for OC and you won't get far without having to highly increase the CPU voltage. That will generate even more heat to dissipate and the stock cooler is not made for that neither.
Don't forget that the stock cooler is there for just dissipate the heat while normal operation (and it doesn't very well neither...).
