use hardware flasher like CH341A to fix bios...

 

I use a ch341a flasher in instances like this.

 

do i need an 1.8v adapter? I read about it somewhere
Thanks!

 

ch341a is your best bet as mentioned above. Flash back to the original bios with it.

 

Well thank you very much. I never heard of ch341a flasher
will do some research!

 

 

Slight hijack, but how is it possible to brick a GPU by flashing a VBIOS to it?

 

Plenty of reasons. Bios doesnt suppor the memory chips, power control isnt giving enough voltage to components, maybe it checks the wrong setup for power plugs and deems nothing is plugged in. Plenty of reasons the wrong bios makes things a nightmare

 

Just ordered this:

Hopefully this is the right one

 

I‘ve got one of those from my DTR laptop days and a SOIC8 clip. I haven’t used it in so long though. Fortunately my current GPU has 3 bios and a switch. But the day will come when it’s obsolete. And chances are I’ll be back to a single bios GPU. 😒

 

You need a CH341A with a 1.8V adapter, although I managed to flash cards with straight 3.3V, it's risky though.
Use "driversetup64.exe" driver from the drivers folder.
Use NeoProgrammer.exe as the flashing software, the other one is flaky.
The red stripe on the clamp cable indicates pin 1. Pin 1 on the BIOS chip is marked with a dot.
Open NeoProgrammer, on the left side, click "detect", from the sub menu choose "IS25WP080 1.8V"
Hit "read IC"
Hit "erase IC"
Hit "program IC" -> browse to the BIOS file you want to flash your card to.
If the hex values are all "FF" and "00" you need to reflash until it looks like below attached. This is my RTX2080, by the way.

 

Thank you very much! Very useful!
I will receive the flasher tomorrow, hope everything goes well

 

You can put another gpu as main, put that gpu as secondary, boot the system and flash the gpu that is not right with its original bios.

 

i got onboard video too, so i tried this. It keeps saying "No Nvidia Display Adapters Found"

 

Thanks! Will receive the item tomorrow. Hope everything goes well

 

Got a big problem lol... They is no space to put on the clip because there is a transistor close to it.....

 

I managed to got it back to life again! Thank you very much for your help guys!
Without you i would be lost

It was not easy, because i had no space to put on the clip.
So i decided to burn off some plastic from the clip 😱🔥
Then i had a hard time to keep the pins aligned with one hand and operating the program with the other hand 🤣
But it's working again! Very happy because it saves me a lot of money
Thanks again friends 👍😻
