Gigabyte GTX 780 Ti Artifacts, crashes, memtestg80 errors and crashes. Faulty VRAM?

[samplerico]

Hi, im a bit desesperate right now, my card is acting weird. Can't handle any game anymore or Unigine Valley or Furmark, always crashes, sometimes with artifacts. Ive tried everything, underclocking, power management. I've tested too the onboard HD4000 GPU, stressing test him and its running fine.

Unigine valley at 1280x960 holds 3-4 minutes until crash using 500MB VRAM, at 1920x1080, on the other hand, using 1000MB of VRAM is crashing almost at start. Ive run memtestG80 and it gives me errors and seconds after just crashes getting some srtifacts. Ive changed thermal paste and thermal pads with good quality ones, temps are fine under 70ºC for the chip, i dunno about vrm's o vram chips cause this card do not have sensors at those. I've tried limiting the power to 90%, 80% and 70% and nothing, still crashes, i've tried increasing power limit and VCore and nothing again.

I'm pretty sure is something with the Vram chips. Any advice? Can i somehow repair vram chips or just limit vram usage via BIOS, or block vram chip whos making my gpu to crash?

Thanks in advance.

Did you try another graphics driver?

Yep , sounds like VRAM went bad , no point in limiting usage to 1gb since that card will be useless then. You could try lowering VRAM clocks if you haven't already , see if that helps.

Yes, ive tried 359.06, 378.78 and 382.53 several times doing clean installs and all.

I have, and it seems holding better and avoid artifacts but crashing is unavoidable, it seems like whenever the bad chips gets work it autmatically crashes or semething.

A guy in another forums said to me that Gigabyte RMA's old cards, mine is probably more than 3 year old. Anyone has experience wiht Gigabyte RMA'ing old cards?

Time to 1070 up

If this card dies, it will be more like a intel hd 4400 down...

You can find old GTX780's for pretty cheap. I've seen them go for around 100-125 bucks.

Check if reducing clock speed on GPU or memory or both (3 separate tests), makes any difference. Also try the card in another computer, to ensure the issue is with the card and not the rest of your system.

Is your's a Gigabyte card? If so the memory is most likely bad. They used a bad batch of memory for the Windforce 780 Ti's.

They all tend to artifact to some degree. Mine at stock clocks has artifacts because of the memory, drop the mem clock and they go away. Mind it still runs perfectly while it artifacts, no crashes, just annoying blips on the screen.

I would give RMA a shot anyway. But most likely even if they do go through with it you'll just get another artifacting one.

Yeah, im looking for that, but i don't like the idea of putting another 3-4 year old card in my system after seeing how mine is dying miserably. Im going more for a second hand 970, and definetely not gigabyte if posible.

Already done, reducing memory clocks helps with artifacts, but i get instant crashings anyway, anytime i put some stress on the GPU.

Yeah is gigabyte, its my third Gigabyte card dying, pretty sick of that company already. Mine seems to have no hopes, underclocking helps with artifacts, but crashes instantly anyway.

If Gigabyte doesn't help with RMA i will attemtp a reflow with some cheap hot air gun or something. Anyone had any positive experience of a homemade reflow? I don't know if that would help anyway since my guess is that the vrams are faulty, reflowing the chip is maybe not the best idea then.

Don't forget they have 3.5GB fast vram only, however I have heard from people here that it wasn't a problem for them but keep in mind newer games use more vram.....

Your issue is defective VRAM , this probably has nothing to do with the solder for the core.

I know, but next to a second hand 970 would be the 6gb version of 1060 and that is going ot be at least 300 bucks, is a bit out of my reach for now. I play at 1080 anyway and i don't plan to go any further. Games i played until now with 3GB vram were running good, even tho i had to lower textures in some cases i can live with that. I guess my next big GPU will be something like 1270 revamped volta chip or something, for now a 970 will do the job.

Yeah thats what i think, but as last last hope it cant hurt. maybe reflowing vram chips can do something.

You should find some local that does memory IC change... ask around in your local tech forums or service locations.
