Ulixm Hey guys, here is the conclusion:
Based on Moparman's suggestion, I've decided to try baking my card again under a higher temperature.
The capacitors have then swelled a little bit, making it a little harder to put it back together with the heat spreader but I was happy to verify that the number of errors detected by memtestG80 have since reduced.
So I've decided to try again!
Unfortunately, the results were not so great this time. The capacitors swelled even more and although I was still able to boot with the card, a whole lot of new artifacts appeared. That's as far as I am willing to go.
I think I might have had better results with a heat gun, as suggested by Moparman, because that would've spared other card components from the unnecessary heating but I don't have one at my disposal.
But that's fine. I knew the chances were pretty low anyway.
Thank you guys for your time!

Details: Running the command "memtestG80 2400 1" gives me no errors but when I run "memtestG80 2500 1" about 43000 errors are detected by the tool... (screenshots below)
Here is what I already tried, but to no avail:

1. "Underclocked" both GPU and memory as much as possible, using MSI Afterburner tool;
2. Baked the card in the oven 3 times already..
That is clearly GPU Artifacts. I would say that card's toast and there's no saving it at this point. I'd just toss it in the bin and get another used one if it was me.

Moparman I had this problem on one of my ref cards. reflowing the Mem ic's with a hot air station and it fixed my card. I guess it had a bad solder joint on one of the chips.

Is there a way to just "trim" the memory of the card so it doesn't even try to allocate the last 500mb? Maybe there is a tool, or a custom driver or even a custom card BIOS that can do this? This is still a pretty good card to run games and that's why I still bother. But I'll just discard it if I can't fix it so I am obviously not worried about voiding any warranties or something. At this point, even plucking memory chips with pliers sounds like an option to me (if I only knew which one to start with =).
The card is a EVGA GTX 780 Ti and I am pretty sure there is nothing wrong with the computer itself once the same games would run just "fine" (albeit terribly slower) with a spare card (Asus 7600 GS).

Mark the Bold Sorry Halp!. Mine crapped out a few months ago. Kept making my computer boot loop. Finally bit the bullet and bought a 1080 gtx. These 780 gtx ti's all seem to crap out at the same time it appears from reading some threads (2.5 years after binning.)
Take solace in the fact that graphics card pricing is now no longer obscenely overpriced . You can get an Rx580 for $250 or a 1080 GTx (refurb) for $350 or you can wait for the 21xx nVidia's. The RX580 new pricing is probably the best bang for buck right now if you monitor slickdeals. Hope this helps.

This is the right forum. It sounds to me like your card's dead. And what do you mean "Rebake" ? You mean bake in the oven or something?

MaxTheMiracle Hi guys, i have green bars all over, and then Black out, on bios, works fine, i guess is because some memory fault, is it wise to downclock the clocks of the memory, or is it any guid to disable part of the memory on bios, to return back to life my 780Ti?
