    Hello, after running some tests I believe one memory chip is faulty on my good old graphics card. Perhaps someone here knows if it's possible to disable a specific memory chip or a memory channel by modifying the bios or the driver? I'm trying to avoid heat guns and ovens for now...

    If the vram is faulty its a game over.

    GPUs are fused for a certain number of channels.
    It's not like a CPU which can work with 1 DIMM, 2, 3, 4... up to 16 on server parts.

    RIP 580
    It was time to upgrade anyway, that card is extremely slow for today, even if it was in perfect condition you can't really play anything with it.

    Too bad the market is also toast like your vram chip...

    Disabled. No
    Replaced. Yes. But is a multilayered yes, first find exactly which one memory chip is bad, second have the replacement part and third, the tools and skills to accomplish that.

    well you can always try to replace it with a new chip, it's a very old gpu, so you can just tweak and manipulate it anyway you like and if it dies then no big deal.

    I use to practice my reballing and resoldering skill with this kind of hardware so the loss it no that big of deal.

    I'd say you're heading for a collision with a heat gun or oven.

    How can you test to locate a faulty memory chip as I have a 1080ti thats pixelating and im thinking its just a faulty memory chip

    in reality by modifying bios something can be done .. you can halve vram or perhaps exclude some channels. but you have to do reverse engineering.
    I managed to re-enable vram on some cards that had 2 gb onboar but they had enabled only 1 gb.

    Even the lowest tier cards should outperform a gtx 580 easily for not much money. Best to look at replacing it.
