On the backplate of my gpu its written Asus Dual RTX O8G means oc version of 2080 while when I took off heatsink on gpu chip it was written TU104-400-A1 and 400 means the chip is not oc version because oc version chip is labeled as TU104-400A-A1 so I downloaded bios of simple Asus Dual Rtx 2080 8G and was successful in flashing. Writing this whole stuff just because I was even unable to flash wrong bios with nvflash mismatch id disabled version. So it can help someone in future if any of you encounter this issue he should first confirm serial on chip. Lastly I thank you all for your precious time.

After failing in this situation, I thought to try mu luck in Dos mode. So I made bootable usb and now it is giving me error no nvidia display adapter found.

My gpu is Asus Dual OC and there are just 3 bios versions and all of them has same id see here https://imgur.com/a/OJr0oSk what should i do now which bios file should i get i am really confused

I got it you can see here my gpu is of asus while bios is of this evga card see here in photo https://imgur.com/a/0tbAQDn

OK thanks for your answer but my question is there.. how to bypass that mismatch id error?

ok here is my simple question if anyone knows how to flash nvidia cards despite id mismatch error please let me know

I don't know and that's the basic question that I am asking here because I have seen many videos about AMD cards people flashing different bios for mining purpose.

no what i assume is that there is wrong bios flash by previous owner for mining purpose

Few things that I noticed are that there are 3 bios version of my gpu on techpowerup and all of them have 1e87 as device id... secondly my gpu shows bios version as 90.04.0D.00.91 while there is not a single bios version on techpowerup that 91 at the end of bios version.

What would you say about EVGA showing in subvendor while this is Asus Dual???

Hello everyone! I have a little problem, you people know gpu prices these days... So I purchased a faulty Asus Dual Rtx 2080 that was giving error code 43 in device manager at really cheap price on a hope to make it work. Previous owner told me it was used in mining and I came up with idea that it might have have been flash with mining bios and flashing with its real working bios can solve issue. So coming to the point, in GPUZ under subvendor option it shows EVGA while its Asus Dual Rtx O8G. I downloaded bios from techpowerup and tried to flash it with following command ''nvflash -6 bios.rom'' but it gave me error that ''pci device mismatch with image id'' I have attached image of GPUZ as well as command prompt showing error. Kindly help me to figure put do I need to force flash it? or is there any hardware fault? https://imgur.com/a/6ZfnJb1

Thanks for your time man I myself got the issue. It was lose pin and that's why I was getting low voltages

I have RM1000X and here is brief overview of issue: I bought this psu in used condition and first time I came to know that my psu is faulty when I used it with 980Ti and it crashed during games while worked perfect with 650w bronze psu. At another moment using this RM1000X two ram slots of motherboard stopped working however those slot started working again by themselves after a week. I sold that motherboard and purchased Z370 Aorus Gaming 7 with 8700K it was fine but upon using Rm1000x two slots stooped working immediately. So at this point I thought to analyse psu so I got a multimeter and checked voltage across 24pin atx and all other connectors that came out of it. HERE IS WHAT I WANT TO SAY: Every thing else gave me perfect voltages even two of 400v capacitors are also giving 402V each so both of them are also fine however I got 0.5V on one of 12V pin 24 pin atx and I mentioned it in below image. So my question is simple No.10 pin in 24pin atx is giving bad reading and psu crashes on load couple of times it created fault in my mobo ram slots. Capacitors are also giving 400V which is good then what could be the problem here with this 12v pin ? Image: https://imgur.com/a/CCOnyNZ

ok guys thank you very much for your responses.
