Question

Video cards

how to calculate used vidyuhi which were obviously not mined according to their characteristics?

Answer 1

Well, just called an expert.
No way. The students were mining on everything. Unless you can take some deshman office.
In general, I advise you not to worry, because nothing particularly terrible will happen to such a card, they are designed for such work.

Answer 2

not mined on a large scale on cards with memory <3GB. That is, on all game cards manufactured in 2015 with 3GB+ memory and younger, it was possible to dig at a loss.
All game cards fall under this definition))
It's not mining itself that's bad, but chronic extreme overheating and overclocking. agree on a moneyback for a few days and drive it as it should.
before my eyes a bunch of gf1060 3GB from a friend working in hellish conditions - 3 years in the 80-90 degree mode. none died, only the fans break.
