I oc'd my 4690k up to 4.6 ghz at 1.26v. The problem is that it runs fine normally, it can even do prime 95 for a quick 5 min test i ran, but about a min or two after the test is complete the pc will randomly reboot. Any possible explanation would be greatly appreciated.

Thanks in advance :)
 
Does your temperature go over 85c?
Test with occt. Prime95 does not test in the same way.
You may have only an average chip that will not do 4.6 at 1.25v. :(
You could increase the voltage as high as 1.30, but it is not advised to go any higher than that.

Better to lower your clock to 4.2 & 1.25v or so and see if you are stable there.
