you tuned your cards on the wrong way ...
if this is the case you might have some components damaged on your cards alreday... that is why what worked fine yesterday is not working today

or you are using a modde bios downloaded from the internet ?

you need to fine tune your cards ...
set back everything to factory default , try to use the pute-Release-Notes.aspx]blockchain driver

change every settings slowly ...
every cards are different , some can handle 2200mhz , some can not go over 2050... from the same manufacturer / same model

I will try with blockchain drivers, yes I'm using modded bios, good hynix mining memory timings from polaris bios editor, it's been okey until now did not have any issues
