Yes, maintaining a stable voltage at the edge of acceptable levels can still pose risks.

I have my 4790k OCed to 44x now and it appears stable so far. My concern is whether a voltage can be "unstable" without causing a crash. For instance, when the voltage was slightly lower once, Windows would restart but only a few of my default programs would launch, and Firefox wouldn't start. Can my PC look stable after an OC while still experiencing minor issues?
Run a test using Prime95 (version 26.6) with the Large In place FFT option, which seems to work best for thermal testing. Try smaller FFT sizes as well. Check for any errors; your computer took about 5 minutes to run and it would suddenly restart. Sometimes this appears as an error in Prime95, or it might cause a blue screen or shutdown. You can also use CPUz for a different testing method.
Based on the job, workload, and processor activity, your overclock might remain steady often, though some programs could exhibit fluctuations.
