Hi guys,
I have two Gainward Phantom GTX 680 4gb cards as SLI.
Everythink worked fine untill yesterday.
Yesterday I´ve realized that I have two differnet BIOS versions on my cards:
- 80.04.09.00.C8 (older)
- 80.04.47.00.0B (newer)
So I decided to flash the card (older version) with the newer bios. (unfortunetaly I didnt create BIOS backup)
Everything went fine, no error messages so i restared PC.
After restart windows 8 x64 stoppes for 30 seconds (black screen) before logon screen, after that the fan of one card goes on 80% and finally logon screen appears. After logon i can see in device manager that one card is working properly but the other one shows following error - Windows has stopped this device because it has reported problems (code 43)
I tried following: (nvflash -i=0or1 -4 -5 -6 file.rom)
- re-flash both cards with the newer bios, also from USB DOS - everything is ok, I can re-flash both cards without issues
- flash the older version back - doesn´t work - i get error "PCI Block corrupted -size mismatch"
- Uninstall all NVIDIA drivers (also with DDU) and reinstall the newest driver - still code 43 error
Both bios files have been downloaded from techpowerup video bios DB.
Do you guys have any ideas?
Do I loose my guarantee due to flash attempt? My cards are not modified in anyway.
I would really appreciate your help.
Thank you in advance
Regards
