Question Confusing Results from MODS (MATS) while Trying to Diagnose my GTX 1080

Jun 27, 2022
I have an EVGA GTX 1080 SC, which will turn on and light up, but will only output a black screen. When I turn the computer on, the card will not output a signal for about 30 seconds, then output a black screen. From what I've looked up, this is indicative of a memory problem.

Regardless, I tried to diagnose the problem using MODS (MATS). However, after running the program twice, the results I got confused me. I got all read errors on every single memory module, with no write or unknown errors. I looked this up, and it doesn't seem like anyone's ever had this issue. I'm not sure what it is. Would anyone be able to help, or know what this is?

Thanks for your help! This has really been bugging me for the last while.

Because I can't seem to upload the .txt report file here, I'll copy the first bit of what it says.
