Question My GPU auto OC insanely and is self-suicide

[HuNTeR-]

Last night my graphic card again raise OC insanely without my permission,but this time exceeded any limits .
i want to say sometime my GPU card froze my mouse on the image for 4 second.I expect soon or later this card fail....
On my entire life i never seen this strange behaviour on ANY graphic card....My card is self-suicide...

default bandwith is 622 GB/s- already OC from the factory
default memory speed is 1768 Mhz -and it s already OC from the factory

Unbelievable...

What can i do to stop this madness?i don/t want this insanely OC without my permission

Must be a non-standard BIOS flashed onto the card. Maybe go with a standard non-OC flash BIOS? Don't ask me where to get that BIOS or how to flash, though. I don't do risky stuff like that.

Sounds like a "mining BIOS". Was this card purchased used?

ETH mining was largely dependent on memory bandwidth / speed.
