Help GPU Crashes | tuning specs mishap?

[Noamazia]

*attached the specs table*

i have Asrock rx 6800 chellenger pro. every time i launched time spy it would crash when started to gpu test 1. (also other gpu stress benchmarks like superposition)

after a few days i figured out that the radeon software has tuning options so i checked it out and it showed that default sepcs are over the manufacturer's specs.

i changed chenged the specs until it passed the test on 92% frequency(stable in games aswell), but then it also ran ok if i started the test on 94% and then raised it to 100% and even 114%(not in games).

even weirder is that when i raised the clock mid run it actually ran slower and got the same resault.

 

is the radeon program reading the card specs wrong?

is my gpu defective?

is 12250~ score ok for this gpu without overclock? (1440p)

 

*the freq seen in test for over 94% is starting 94% and then after 1 sec change to 100% or 113%
