Hello guys,
I have i5-4690k on msi z97 pc mate with cooler lucifer k2. I overclocked it to 4.5 GHZ and started aida64 test. After an hour the computer showed blue screen and the following text:

You have to have researched OCing, increasing voltage could kill your processor now, next week, next year, in 2 years. You choice as to what risk you want to take. It could also kill your mobo at a random time. I lost one mobo within 5s of what should have been a perfectly safe OC. If you have read that between 1.2 and 1.3 is safe, you have to understand what their definition of safe is, is it 5yr safe? do you care if it is not 5 year safe? These are things that only you can decide, after you have investigated. In my case above if I had asked someone 'is this safe' they would have said yes, then how would I feel when it died? Instead I researched, I decided, so it is my fault, which is the way that you have to make these decisions. I...

I will feel safe even if the computer explode and i am not at home ... how do you expect me to feel safe with whatever kind of stuff related to hardware .. i am not a processor and i dont know ... i've read that a core voltage between 1.2 to 1.3 is safe

I could have had a bad board that was about to go anyway. who knows, certainly not the person saying that it is ok.

I raised the core voltage to 1.257 and the computer ran aida64 for 4 hours before show the screen. Will this mean that if i made it 1.260 it may become stable? And can it be a problem made by the Windows ?

My last try is with 1.260 and if it fails again i will just drop it to 4.4GHZ and make it stable. Another question - in aida64 the core voltage is 1.287 as in the BIOS it is 1.260 ? How ?
