Question 3090 Bios not posting HELP!

[tonybrowntown]

I have an Inno3D 3090 iChill X4 that is not posting so I connected a Skypro to the ISSI chip on it and I can erase, read and write however the first sector on the chip gets lost.

Does this mean I need to solder on a new bios chip? Any workaround?

I tried to offset by one and no post.

You can see here when I open it has NVGI - >

When I write it changes to a '.'

Confirmed that is the only change to the write -

Any ideas?

Also I cannot seem to find any of these ISSI chips in stock anywhere...

was it working before?

Yes it was . It was restarting sometimes, and I isolated it to this card. It was posting fine then just stopped.
