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

default memory speed is 1768 Mhz -and it s already OC from the factory.

Unbelievable...

 

What can i do to stop this madness?

Underclock using Afterburner. Something doesnt smell right here.

i downclock -502 MHZ on memory.It's safe now to prevent any self-suicidal damage?

What clocks does afterburner report? GPU-Z is likely giving wrong values.

snip

you cant kill anything with frequency, only voltage can do that but only >2v and i dont think you can adjust voltage

 

run furmark in the background and raise the sliders till you see artifacts or instability then -10 - -20 on your max stable clocks to ensure stability

 

stability is the only concern here
