Odd...how much did you overclock?
Paste OverdriveNtool.ini or your settings for memclock etc.

nothing extreme
Your memory OC is probably too high for this specific GPU. Dial it back to 935 and see if it hashes without failure then work your way up slowly.
thanks it was exactly the issue !!! I lowered the mem clock to 1050 and it's just smooth and stable !! Thanks a lot it was almost rma state

I managed to install another vega 56, this one, with a damaged cpu crystal !! but still getting 1900h/s when a litle bit overlocked goes up to 2100h/s


Thank you very much the issue is solved.
Happy new year
