Machine Check Exception is a hardware related issue, and overclocking is one of the most frequent causes of it. this error may occur in two bugchecks, either ox9C or 0x124 (with first parameter 0). Overclockers are aware of it. They choose their optimum OC settings by a trade off between the aggressiveness of OC and the frequency of machine check exception.
CPUID: "Intel(R) Core(TM) i5-4690K CPU @ 3.50GHz"
If you want to debug these BSODs, stop Overclocking. Run all the hardware components like CPU, graphics card and RAM at their stock clock settings.
If the BSOD occurs even at the stock hardware settings, let us know. Further troubleshooting will be needed in that case.
