I prefer to play 2-3 games that stress the card at 100% and than up the voltage by one step and i will be 99% stable. A game will never cause a vdrop/stress like occt.
Our cards are literally built for throttling when a extreme load is applied.
Thats my opinion.
Cpus are different, they are very sensitive to errors.
Yeah with boost, I do a bit of a trick to test a more steady game rate:
I find the max fps loaded, let's say 400 fps.
Then I try 300 fps and watch the clock, it should be higher and throttle less.
Powertune tuning also helps with occt. Let's say you want to find out the max steady power that doesn't overheat your card... you back down on powertune until it's stable and not overheating. For example on my rx480, around 150 watts is the max steady reliable power.. past that GPU can go above 80 C and start throttling power on temperature.
I run my occt test at 640x480 with fps set to where I use around 130 watts for a steady test with the powertune around 150 watts (calculated from my bios set to 140watt, using 7% pt to get 150 total watts where card throttles).
Games don't tell me whether there are errors or not, once you see an artifact, there's been hundreds/thousands of errors that lead to that!
The rx480 is less crazy, but on my 7950, if I didn't do my occt torture testing for error free, it would randomly give me issues in some games, depending on the level. Some levels stress memory or the shaders more and you won't know until you're deep into the stage and boom, crash or some really bad artifacting!
