We have been reported by one of our customers that our application compiled with the compiler from IPS XE 2017 Update 2 crashes on random occasions while the calculation is running. We ran the same calculation with the same executable on several computers and did not experience any crashes. The customer has recently reported that the application stopped crashing after CPU overclocking was disabled on the computer that is Alienware.
Is it possible that CPU overclocking would cause application crashes?
Yes, it's quite possible for various applications to crash on overclocked machines. If you do a web search for "cpu overclock crash", you will find quite a lot of information about it.
