"Dead" EVGA GTX 780 Ti outputs video, bad bios?

sam_86314 · Jun 28, 2019

Today I stopped at another local computer repair shop, and while I was talking to the owner, he showed me an EVGA GTX 780 Ti Superclocked that he had. He said it didn't work and asked if I knew about reflowing cards. He said he didn't have the time to work on it and gave it to me for free.

I stuck the card in my old 2600K system, and to my absolute shock, it booted and was outputting video! Opening GPU-Z showed some... interesting results.

My guess is that this card has a bad BIOS. Maybe the previous owner tried to flash a mining BIOS and failed?

I've never reflashed a GPU BIOS before, so can anyone give me some tips? Or can anyone spot something else wrong with this card?

03g-p4-2884-kr suggest it's an EVGA GeForce GTX 780 Ti Superclocked w/ EVGA ACX Cooler ( https://www.evga.com/products/specs/gpu.aspx?pn=e4755ea0-12df-4f22-aba3-650c494d83dc )

then one of the stickers there is nice enough to say the vbios version it came with: 80.80.34.00.80

you should wait for @eidairaman1 opinion (my personal opinion is that this is the right bios for your gpu (i repeat wait for someone else opinion also and I assumed the sticker on it are the right ones) : https://www.techpowerup.com/vgabios/152799/evga-gtx780ti-3072-131126 )

what I really don't like is that GPU-Z shows nothing. by any chance can you post the Device ID of the gpu (either from windows device manager or by a tool like aida64, hwinfo or any other tool that shows device id).

gpu has 2x dvi, 1x hdmi and 1x dp ports right?

Yes, those are the outputs it has.

I'm noticing some very slight artifacting when using this card. Very faint blue patterns on my browser window occasionally.

Edit: I ran the driver troubleshooter through device manager. While it made GPU-Z work a little better, it also made the artifacting much worse.

Took a picture of the screen with my phone so the artifacting is visible.

Does this mean reflowing the card is the only option?

I'll do more testing after work tomorrow.

Reflow or bin it.

I would suggest you to flash GPU first, as my 950 which I own was also spitting the collors on DVI-I output, only HDMI worked for 20% of the time, after flash it got working again normally.

Reflashed the BIOS, still artifacting. Pretty sure it's a hardware issue.

I'd rather put it to wall rather than trash it

for the OP: If it still doesn't work, it's reflow time..

To be honest I don't really like the reflow idea. I'd rather do reballing, done right it will last considerable longer compared to a reflow. Ofc reballing cost more than reflowing...

For the cost of a re-ball on a card this old, it's probably better to just get another one or a different card all together.

Heat gun for removing wall paint and some flux would do the job.

Just make sure that you cover capacitors and other components with kapton tape or aluminium foil especially the capacitors and direct the heat gun to gpu chip.
