I believe that most tests have lost their relevance. They can only reveal obvious problems.
I get the impression that FurMark creates a large even load on the card, and problems are most often caused by asymmetrical loading. FurMark creates such a large load that the fans on my video card don’t come on until 5-10 seconds after startup, and I don’t even know if the stress test has started unless I look at the monitoring. This is clearly a bad kind of testing. Oh, and the rest of the tests are from the same series.
When checking the CPU, for example aida64, the stress test gives a lower CPU load than the performance tests. This is just ridiculous.
And the problems usually start when the air in the case starts to warm up.
For example it can be useless to test RAM if the case is not running the video card and CPU at full power, thus warming up the air in the case.
As long as the memory can be cooled by cooler air, it can remain stable like other hardware.
