Does anyone have experience with diagnosing / changing memory modules on #Nvidia GPU?

I have a semi-broken #1080ti laying around, and I'd like to #diy #repair it to make it useful again: https://toot.kottman.xyz/@michal/105216236032017261

I've not been very satisfied with my #Arc750 purchase, ever since I installed it, I'm experiencing roughly one unrecoverable lock-up per week which requires a hard reboot.
