Hi all,
 
I am looking for some opinions from the knowledgeable community. I have a SLI setup with 2 1080 Ti SC2 Hydro Coppers. I recently did loop maintenance and decided to place the bottom card as the primary since it largely sits unused in the majority of titles I play. Wargaming titles and Farcry 5 crash with critical errors, others, like Metro Exodus, DCS world, Apex Legends freeze momentarily during the gaming session (FPS drops to zero) but I am able to keep playing, just annoying with repeated freezes. 
 
I have been testing the last several days running the cards one at a time and the card isnquestion does all the above without fail. I don't see any artifacts and temps are mid 40s. The other 1080 Ti runs with no issues at all. I even placed a 1060 in and it worked great. I have done the usual trouble shooting steps, DDU, reinstall drivers ect.... Rest of System
