Can you swap a bios chip on a GPU?

[MARSH.]

Ok so i have a gtx 1080 that i bought from a fellow carbie as a project. At the moment what the card does is it artifacts on dark coulers and windows says there is a problem with the display adapter. When i put the card in a pc with no Nvidia drivers there is no display. I have opened the card and it looks like the bios chip has been worked with. So where im currently at is that it was probably a miners card and he put a mining bios on it not sure if that is a thing though. I have found replacement bios chips on Ebay for like R500 with shipping so do you guys think that might be a fix to replace the bios chip with a new one?

He and I had this very discussion the last weekend
He's working on doing BIOS chip programming in-house, but of course he can change the (pre-programmed) chip for you if necessary

PM him (His shop is also in CPT)

*On the other hand, when a card artifacts it usually points to a memory fault
It may be (not necessarily) the cause of the timings and clocks of the memory being off from what the GPU memory is capable of (bad/wrong BIOS)

Usually with a BIOS that's bricked, you will hear the fans spin up max speed and show no display at all - failed flash or some other prob, have an experienced person (@Psychomaniac) look at it

It's a Nvidia card so before you do anything in terms of spending money to have someone replace the bios chip run MATS and MODS on it. There should be videos on how to use it by https://www.youtube.com/c/TechCemetery/videos?app=desktop if not he'll have a link to it somewhere.
Should tell you if it's a memory chip fault or a memory controller fault or something else at least.

If you have error 43 in device manager, you either have a bad GPU core, bad VRAM, or bad VBIOS. VBIOS can be excluded by reflashing it, VRAM by using NVIDIA's MODS/MATS (as the previous poster suggested)
