How long should I run Heaven Benchmark to ensure a stable overclock?

I recently tried overclocking past the usual frequency I set in MSI Afterburner which was around 220-240 on the memory clock and 135 in the core clock. Now I set the overclock to 260 and ran Heaven Benchmark it survived the first test... but how long should I keep the test running to ensure that it is already stable? 260 is as far as i can get to avoid the computer from crashing.

BTW I am running it on my laptop with a Core i5-6200U and 940MX 2 GB DDR3

Honestly, I don't consider establishing GPU overclock 100% stability up front as critical as it is for a CPU overclock. If you've run it for a little while (maybe 15-30 minutes), it's probably stable or nearly stable. If you experience any graphics artifacting or driver crashes in the future you can just bump up the voltage a bit or reduce the clocks a bit.
