Question Graphics card overclocking test by objective way

[deskman1234]

I learned graphics card overclocking test: Checking glitch by own human's eye . How can I know hidden error if I can't see tiny glitch? Is there objective way to check the overclocking error?

If I recall correctly, OCCT has a GPU test that checks for errors.

But if you just use your card for gaming, does it matter of there are imperceptible graphics errors? By definition you'll never notice them.

If you cant see the artifacting then the OC has no tangible impact on you, and is therefore fine.

In general, artifacting is very noticable. Flickering textures, shadows etc. Weird colors.
I would test with Unigine Superposition and pay attention. Run it once with stock settings to establish baseline.
If the benchmark crashes or artifacts, dial down the OC.
