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

samplerico · 30 Jun 2017 at 12:34

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.

RMA it ? Gigabyte repair is pretty good. I think they repaired cards that were over 3 years too.

I've contacted them asking for warranty and they said all sorts of basic things about troubleshooting that i have already done but nothing about warranty or RMA'it. My card is indeed older than those 3 years (i think) if thats right i will re-contact them for an RMA. But doubt they will free RMA a 3+ years old card honestly.

I think some people were able to get a repair but were told if the repair didn't work they wouldn't get a replacement. Might be worth messaging the Gigabyte rep on these forums to see if anything can be done.

I've contacted them again, waiting for a anwser. If they don't have any good news for me i guess my only chance right now is to prepare my oven for a hot session...

Please don't put it in the oven lol.

Ive read lot of people had revived dying cards that way. Its not that bad as a last last option.

did you check the temps on it?

LeMson · 1 Jul 2017 at 21:15

Oven it if you get no help from the gigabyte rep, if nothing works don't buy a gigabyte again

Yes, temps on chip are fine, i even changed paste and pads.

If gigabyte doesn't help i will try the "oven technique", and yeah, i will never again buy form gigabyte i hade three GPU's and one motherboard deads from this company...Asus on the other hand never gave me a single problem. I will try MSI next time.

Try Zotac, 5 year warranty if you register in 30 days or sommot

mickyflinn · 1 Jul 2017 at 23:02

Worst time to get a new gpu as prices have rocketed up, 3 years warranty is just that.

Ill keep it in mind

Yeah, i was looking for something like a GTX 1060 6GB and they are at least 320 bucks... i don't know if its normal but it looks pretty crazy for a mid-end card.

LeMson · 2 Jul 2017 at 00:08

Prices are crap unless your going for a 1080ti, vega should be out soon which may help everything, just sucka now buying :'(

Did you try underclocking the vram.?

1080 is out of my reach for now, and i sadly decided, some time ago, to buy a gsync monitor, now im stuck with nvidia...

yes, and this is helping with artifacts, but crashes just happens everytime i put some minor stress in the gpu anyway.

if RMA doesnt go well, Gibbo doing a deal on the G1 1070's
My basket at Overclockers UK:

1 x Gigabyte GeForce GTX 1070 G1 Gaming 8192MB GDDR5 PCI-Express Graphics Card (GV-N1070G1-GAMING-8GD)= £488.99
1 x Voucher= £-60.00

Total: £428.99
(includes shipping: £0.00)

bit more pricier then 1060 but I dont think costs of them will come down any time soon.

With the Zotac warranty, does OCUK cover the full 5 years or is it only the first 3 directly ?

Lower power target to 60 or 70 percent then try. Could be vrm temps
