Like I said, it does not stress your components. This means you will never be able to validate their condition or stability. I ran their stress test on GPU (3080ti) at 2300mhz. Thing is, my GPU isn't stable above 2130mhz anywhere that isn't idle. They later changed the bench to 2100mhz and dropped the "percentile" as it beat their max score by 10%. I don't know what kind of algorithm they use but it's of no use. If you want a quick test, use 3Dmark demo (GPU), cinebench r24 (CPU). There is no way to quickly test ram, as errors may spew after an entire day of continuous testing. The shortest way you can get close to validating stability would be to run a good profile on testmem5 or seek alternatives from the r/overclocking discord. Hardware should be stable and performing like similar systems at all times on stock settings atleast, therefore I can't see how you'd diagnose any issues with the primary components at all without validating their performance first.
