So, I've had my i7 4790k for a little over 9 months and overclocked it to 4.6GHz at 1.175v 4 months ago. Now my issue is that, recently, my PC has been crashing with the WHEA_UNCORRECTABLE_ERROR. That error means that the PC is unstable/has a bad overclock. I never used to get this error before but now I've gotten it twice in the last two weeks. If my CPU was unstable, I would have crashed or BSOD'ed long time ago as I have stressed the CPU using both [old] Prime and x264.
