I have just started to overclock my 4690k that runs on a msi z97s sli krait edition motherboard. CPU temps are pretty great with my corsair h75 keeping temps below 50C at 4.2ghz. However, as soon as I try t pass 4.2 ghz, I keep getting BSOD. I kept the voltage at adaptive because when I had it on override (1.25 on voltage), it kept crashing no matter how much voltage headroom I gave the chip. Also, the uefi bios keeps freezing up so I cant use my mouse or keyboard but the temperature monitor and time keeps running. I dont know what to do anymore, and is it possible I got a really bad chip?

Unlocked chips are like the lottery, you can get awesome chips or in your case get one that only oc's 300mhz over the "boost" clock. Have you tried to update the BIOS and retry?
