I believe my TITAN's VRAM is failing on me, and I don't know what to do. I've tried taking out my RAM sticks, putting in just one then testing and everytime I get weird texture popin no matter what I do in games. (e.g. GTA V tree's don't load in until I'm next to them - Witcher 3 road pebbles, tree's and birds don't render til I'm near it - F1 2016 the shadows are a bit glitched and at a certain track *mexico in the rain* the rain looks all flickery and stuff just like the building in GTA) I've even underclocking the VRAM to the lowest point in precision X and it's still there. I've tried reinstalling the Nvidia drivers, re-installing OS and all the Intel drivers, etc. And I've even underclocked the CPU to 3.5GHz and disabled HT to see if it helped at ALL and it hasn't (I7 4790K). Oh, and my RAM was underclocked to 1333 from 2400MHz. Now, my problem is I can't even return the card as it's a Hybrid put together by a very well established Youtuber who knows his stuff before anyone says he doesn't but I won't mention his name for his sake. Does anyone have any idea's what to do?
