Heya Peeps,

I splashed out on an XFX 8800GTS 640MB XXX Edition (600MHz core 1500MHz shader and 1900MHz RAM) thats all good, I have had it OCed further to 630MHz core, 1566MHz shader and 2040MHz RAM via Rivatuner, thats all good.

I now decided that I wanted to flash the BIOS to keep the settings to keep startup items to a min and so I flashed the BIOS with nvflash -5 -6 ocv.rom (ocv.rom had the clock speeds above and 1.35V core up from 1.30V) it said that it flashed successfully, so I rebooted and it wouldn't boot, the mobo hung on detecting VGA and the GFX cards fan was going nuts.

I tried with a PCI card to flash it back, but it still hung... I am currently running on my old 7800GTX 256MB which I have flashed many times successfully... Any ideas how I can get this back to normal? (if at all possible) do you think I would be able to RMA it?

Thanks :)
 
I'm assuming you used nvflash to do this? If so, did you back up the original bios first? I'm sure you can blind flash back though unhelpfully can't remember how to do it, :o. There is a site that's dedicated to all things of that nature...[size=-1]www.mvktech.net, sorry to be vague but I haven't flashed any graphics cards since the 6800 era. I'd have a nose on there and get the info on how to do it.

Have you tryed putting in only the PCI GPU card and booting into the motherboard bios and setting the motherboard bios to display the PCI GPU card first,and then shut down and add in your 8800 gpu card...???

Well I had a look in the BIOS and it is set to use PCI as the initial display...

BUT when I have a PCI-E card installed it defaults to PCI-E... Even though it is set to PCI in the BIOS... I can boot with my old 7800GTX and look in the BIOS it still says PCI, but the PCI card display does not come on till XPs login screen.

I will see if I can try a friends mobo on the weekend.

I might add my system specs...

Athlon X2 4400+ @ 2.7GHz
2GB Legend DDR400 @ DDR450 2.5-3-3-7
DFI NF4 SLI-DR
XFX 8800GTS XXX Edition (Legend 7800GTX as backup)
 
OK, I have finaly got time to get this working... near on a week after I flashed it... :eek:

Anyway, I thought since it defaults to boot from PCI-E even though PCI is selected in the BIOS I would try my 7800GTX in the primary PCI-E slot and the 8800GTS in the secondary slot, this is successful, I can boot and Windows detects the card and want to install drivers for it :D

Now what can I do? try to flash with the 7800GTX in aswell? or is that not the best idea?
 
Good its being detected, means its not totally scrambled. Haven't used Nvflash or flashed a BIOS for a gpu since my X800 VIVO and 6800 days, can you select which device to flash? also would it not detect that the BIOS is incompatiable with the 7xxx card?
 
I am not fully sure if I can, I assume so, I do not know nvflash to the extent that more advanced users will... Again, I assume it will detect that it is incompatible, but a more advanced user will need to verify this.

I went to read BIOS into nibitor and it is corrupt... gave 2 errors which were in anther language and asked to select which series the BIOS was from... and displays random text in the Vendor, Device and Date...
 
Heya Peeps, it is a good night :D

I was able to flash the GTS back to factory with it in the second PCI-E slot with the 7800GTX in the primary and I used this command: nvflash.exe --index=0 -5 -6 backup.rom.

Thanks for your help :)

Now its up and running, will you be retrying some sort of BIOS update again?

I quite fancy doing mine, but don't want to kill it :p
Click to expand...
Quite possibley :p

As soon as I got it back I was into OCing with Rivatuner :p

I suspect it was a corrupt floppy disc I used... (can never trust em these days...)

EDIT: flashing the BIOS with new clocks gets rid of 3rd party software on boot to enable the new clocks which is why I flashed it... got to keep a nice clean install of Windows...
