It would cause system instability (programs/games crashing) when running normally. I had to underclock it through Intel’s XTU to make things stable again.

This was after all the BIOS updates from ASUS and with all BIOS settings set to the safe options.

When I originally got it I did notice that it was getting insanely high scores in benchmarks, then the story broke of how Intel and motherboard manufacturers were letting the CPUs clock as high as possible until they hit the thermal limit. Then mine started to fail I think about a year after I got it.
