HOWTO: nVidia BIOS Flashing - Page 2

post #11 of 507
could you guys suggest a performance based bios for 7600gt (xfx and bfg)...also would crossflashing different SLI rigged cards to same bios be overtly stupid?

First some cards have 256mb and 512mb make sure get the correct BIOS, you can cross flash cards like using a BFG BIOS on a eVGA it works some people do it As long as both cards are the same like 8800GTS & 8800GTS, but I prefer to use eVGA BIOS on a eVGA card ECT.

I've only ever had one bad flash when flashing a FX5900GS to a FX5950ULTRA but I had a backup and flashed it back.

1. Download the correct BIO's file you need here NVIDIA BIOS LINK

2. After it's downloaded Rename this file to 1.rom

3. Download this program nvFlash v5.38 nvFlash LINK

4. Unzip nvFlash v5.38 create a folder on your desktop paste all of it in the folder it should look like this,



5. Install a floppy in my computer right click it format and reformat it for MSDOS then open it.

6. open the folder with the nvFlash,cwsdpmi and the new bios 1.rom copy and paste them to the floppy, now the floppy should look like this,



7. Restart the computer with the floppy in.

8. Making a backup once you get to MSDOS and see the {A:\\} prompt next to the prompt type, nvflash -b backup01.rom (This Backs up your stock BIOS, just in case you have to flash it back)
IT' ALWAYS A GOOD IDEA TO CHECK THE FLOPPY TO MAKE SURE THE BACKUP TOOK



9. Normal BIOS Flash, next to the {A:\\} prompt type, nvflash -5 -6 backup1.rom This should flash it if it doesn't you force flash it.

10. Force flashing, next to the {A:\\} prompt type, nvflash -4 -5 -6 backup1.rom
That's it remove the floppy and restart, DONE


Now if for any reason something went wrong you have the backup on the floppy so you just do step 9. again with nvflash -5 -6 backup.01R flashes it back to stock.

nvFlash v5.38 Commands...
"nvflash -b backup.rom" (Backup your BIOS)
"nvflash -5 -6 backup.rom" (Normal BIOS Flash)
"nvflash -4 -5 -6 backup.rom" (Forced BIOS Flash)

I searched for Korndog2003 in the faq section he doesn't give you enough details if you ask me, try FLASHING it the way he tells you and see what happens...

Hey guys,

Quick question - My GFX card is a XFX nVidia GeForce 8800GTX 768MB DDR3 Dual DVI/TV Out (PCI-E) which has so far been oc'd with Rivatuner to 605 / 982.

Anyway i was looking through the XFX bio's category on mvktech.net, and found this one - XFX 8800GTX (XXX) PCIe 768MB - Rev 01 which was submitted on 08 January 2007.

I was wondering what benefit would this actually bring flashing my xfx card, and is it actually recommended for someone who knows very little about oc'ing. Also can we trust that the bio's files from mvktech.net are actually geniune and not half arsed files that could seriously damage our cards.

Thanks

CC

is there any way of doing this through windows or do i have to do it in msdos

I have a Gainward 7800GS+ AGP 512MB the 8255 version and my standard clocks are 450/1250 and should be 500/1400 Gainward say they sent some cards out with the wrong bios mine is 5.71.22.12.GP and i have found 5.71.22.12.03 i assume it should knock it up to the proper settings and looking at the 71 i think this means G71 chip which should have 24 pipes and 8 vertex so will i be able to unlock the 4 pipes i'm missing.

Using NiBiTor i found that the bios is the same 1 that i've found so there is no point flashing that is there.

You have to do it in dos only. the only benefit to flashing bios on an 8800gtx would be to go to a factory overclocked bios (this will invalidate your warranty if the card dies before you have an opportunity to flash it back).l Also, you can overclock the card manually.

Nice an Informative.

Good work.
post #19 of 507
Cool, now i've sorted my standard clock settings they should have been 500/1400 but Gainward reckon they sent out some with the wrong bios so i ended up with 450/1250. Now all i need to do is unlock the 4 pipes i'm missing. How do i do that?

It doesn't void eVGA's warranty,
I like it because I don't have to mess with it, also it's good for vista since you can't OC with vista yet.
