NVidia: How To Flash a Video BIOS for Hardware Overclocking:

Introduction:

Sick of having to constantly play with slider settings to overclock your NVidia-based video adapter? Want to overclock a piece of hardware permenantly so no matter what system the card is installed in, it is always operating at your desired clock speed? This guide will show you how to do just that, eliminating the need for any 3rd party software utilities to overclock your card (such as PowerStrip, RivaTuner or CoolBits).

Legal Disclaimer:

WARNING: Myself, Short-Media or any of Short-Media's subsidiaries are NOT responsibile for ANY damage, abnormal system behaviour, graphics corruption, game incompatability or data loss that may occur to your hardware (and supporting systems) from performing this modification. By following this guide, you acknowledge that you have read and understood this warning, you are aware of the inherint risk of modifying computer hardware, you are aware that this modification will VOID any warranty that you currently have on your NVidia GeForce-based video adapter and that you are solely responsible for any damages or abnormalities that occur with the video card.

Software Required:

-> DumpBIOS (http://www.short-media.com/img/nvbios/dumpbios.zip)
-> X-BIOS Editor 1.0 Version 520 (http://www.short-media.com/img/nvbios/rvbsetup10520.exe)
-> NVFlash 4.41 (http://www.short-media.com/img/nvbios/nvflash441.zip)
-> dos4gw.exe (http://www.short-media.com/img/nvbios/dos4gw.zip)
-> Windows 98 Boot Disk (someway to get to a REAL DOS prompt) (http://www.bootdisk.com/)

Steps To Perform Modification:

1) Copy the following files to a freshly formatted floppy disk:
DumpBIOS.exe
NVFlash.exe
dos4gw.exe

2) Restart your PC with the Windows 98 Boot Disk.

3) Insert the floppy disk with DumpBIOS on it and type "dumpbios" at the command prompt. This should save a copy of your CURRENT video card BIOS to the floppy.

4) Restart your PC to Windows and install the "X-BIOS Editor".

5) Open your saved BIOS file from the floppy disk with the "X-BIOS Editor".

6) Click on the "Initialization" tab.

7) Change the core clock (GPU) speed on each & every line.

8) Change the memory speed on the FIRST LINE.

9) Save the edited BIOS file to the floppy disk (using a different name than the one given to the BACKUP of your ORIGINAL video card BIOS, such as "newbios.bin").

10) Restart your PC with the Windows 98 Boot Disk.

11) Insert the floppy disk with NVFlash (and your new BIOS image file) and enter "nvflash.exe /f newbios.bin" (without the quotes and substituting newbios.bin with the actual file name).

12) Restart your PC.

Your video card will now be permanently overclocked to whatever values you set in the BIOS image file.

WARNING: Do not attempt this modification on ANY GeForce 4 Ti video card with 8x AGP support (NV28) or GeForce FX (NV30 & NV35). The NVidia BIOS Editor DOES NOT have proper support for your device.

Are there any other tricks out there that WILL work for a ti4200 w/ 8x AGP? Can you flash a different bios and fool it as in some others and if so which ones?

Nope, it won't. The NVidia BIOS Editor hasn't been updated in ages and doesn't support ANY GeForce FX hardware or GeForce 4 TI's with AGP 8x Support.

Whenever a new NVidia BIOS Editor is released, I'll update the thread :)

TheSMJ: Glad to know it worked! Tried it on my Asus Ti4400 and it worked like a charm :)

Using the "read from memory" option from the X-Bios editor is the same thing than using the dumpBios isn't t ?
And What do you think it will happen if I load the Fx5200 Ultra bios definitions to my Fx5200 ?

2 Nov 2003, 7:57pm

i did almost exactly what you wrote simguy, except for the fact that i put all the necessary files on one disk, including the bios and the flasher.
the problem is that i get an error message when i start the nvflasher, namely that the DPMI is missing or something like that, i forgot the correct message *sigh* ----> see edit

just wanted to know if you or anyone else here ever encountered that problem or at least could give me a hint what to do.

thanks in advance ;)
bozz

eeeeeeeeeedit:

1. i've now done used 2 disks, just to make sure ... same sh*t, different day ;|
but i've got a little more info on the error messages this time:
- when i enter nvflash /f mygf4600.rom, it says "Load error: no DPMI - Get csdpmi*b.zip"
- when i use dos4gw nvflash / mygf4600.rom, it says "can't load executive format for NVFLASH.exe

any ideas ? :(

edit #2:
should've remembered that i hadn't tried google yet ... i've flashed the bios successfully, but the problems remain (suppose i've damaged the card when i tried to install a different cooler)

Is this an original Ti4600 or a Ti4600 with AGP 8x support?

If it's a 4x, I could attach the image of the floppy (with all the files) I used to flash mine.

Just lemme know.

SimGuy

15 Nov 2003, 2:52am

I've added the newest X-BIOS Editor (updated to support new AGP8x TiXXXX series cards and the GeForce FX series of cards) along with a new version of NVFlash (441 versus the older 428).

I haven't tested either of these applications with any of my own personal cards, but seeing as they are updated versions of the older files with new device support, they should work just as well as the older ones did.

I have the same problem as "buzz":

Here's an explaination of what this "DPMI" is and what looks like a solution. I'll tell you right now that I have never run into this problem when working in DOS mode at all. Are the 2 of you who are having trouble using a boot disk made from bootdisk.com by chance?

I've attached the required CSDPMI4B.ZIP file, but again I haven't tested it and have no idea how to use it. If you could, try using an official Windows 98 Boot Disk (made from a Windows 95/98/Me installation) before trying this CSDPMI4B stuff. I don't know how it works and I haven't tested it.

GNU sed is just the DOS application referred to in the documentation. I'm guessing the same parameters & situations could be said about any C/C++ program made for use in a DOS Protected Mode Interface.

5.4. What is CSDPMI*B.ZIP and why do I need it?

If you boot to MS-DOS instead of Windows and try to use GNU sed v1.18 or 3.02, you may encounter the following error message:

no DPMI - Get csdpmi*b.zip

"DPMI" stands for DOS Protected Mode Interface; it's basically a means of running DOS in Protected Mode (as opposed to Real Mode), which allows programs to share resources in extended memory without conflicting with one another. Running HIMEM.SYS and EMM386.EXE is not enough. The "CSDPMI*B.ZIP" refers to files written by Charles Sandmann to provide DPMI services for 32-bit computers (i.e., 386SX, 386DX, 486SX, etc.). Download this file:

csdpmi4b.zip

and extract CWSDPMI.EXE, CWSDPR0.EXE and CWSPARAM.EXE from the ZIP file. Put all 3 CWS*.EXE files in the same directory as GSED.EXE and you're all set. There are DOC files enclosed, but they're nearly incomprehensible for the average computer user. (Another case of user-vicious documentation.)

If you're running Windows and you normally use a DOS session to run GNU sed (i.e., you get to a DOS prompt with a resizable window or you press Alt-Enter to switch to full-screen mode), you don't need the CWS*.EXE files at all, since Windows uses DPMI already.

I would be very thankful if someone could dumb PNY FX5600 Ultra bios for me. :)

I was flashing g/card bios first time when i put Gainward bios on this card and didnt know how to make backup from original one. :(

This works in PNY card,but PNY bios was faster than Gainward.

SimGuy

2 Dec 2003, 4:06pm

WR-HW95, I've looked everywhere for a PNY GeForce FX 5600 Ultra BIOS, but all I can find is the Gainward ones.

Unless you can find someone with this card, you may be out of luck. :(

Hi,

I'm trying to flash my Aopen Aeolus Ti4200-DVC128 4x AGP
from bios version 4.25.00.30 to 4.25.00.37.....

Working with WinXP Pro SP1, NTFS format, on a Abit KR7A-raid (no raid config).

So I followed the guide of this forum.
I tried to use a win98SE bootdisk or Doctor Dos Flash,
to get into DOS.
On a second disk I putted the files I think I needed,
dos4gw.exe, NVflash.exe, and the rom file vid_bios_nvidia_gf4ti4200_4.25.00.37_250_444.rom,
which I renamed to vid_bios.rom and also to vid_bios.bin
with the help of rvbsterup10520.exe (just to rename it, didn't change settings).

My intension is to use rivatuner20RC141 and softQuadro4 to
upgrade my videocard (I do alot 3D work..)

So I putted in the win98se bootdisk, removed when loaded,
inserted the second disk with nvflash etc.
tried several commands I found on different forums, but it won't work.
Or I get the "no DPMI" error or the error from dos4gw (something like no executable file command)

I tried the following commands

nvflash vid_bios.bin or .rom
nvflash.exe /f vid_bios.bin or .rom
nvflash -fvid_bios.bin or rom
dos4gw nvflash /fvid_bios.bin
and so on and on
tried several combinations (made first a backup of the original bios)

Most of the time I get the no DPMI error, get csdpmi*b.zip

What am I doing wrong?
Somebody has any idea?
Do I have to download the csdpmi*b.zip file?
Where do I put it? Also on the floppies?

Any idea or suggestion would be really great.
Thanks in advance.

Alyssa,

First off, welcome to Short-Media! :)

The CSDPMI problem can be explained with this post above SimGuy's CSDPMI Information (http://www.short-media.com/forum/showthread.php?postid=68485#post68485)

I've personally not ran into this CSDPMI problem, so I can't say with 100% certainty how to fix this problem. You could try the file available for download in the post linked to above.

The instructions are to download it, and extract those files to the floppy disk that contains the NVFlash utility and BIOS files.

These CSDPMI files are to offer the NVFlash utility (programmed in C) the required memory management applications to allow the utility to run correctly. Without those, you get these wonky errors that won't let the program run.

Try it and let us know if it works :)

For the PNY bios try using an MSI bios as MSI manufactures PNY's cards (or at least they made the TI4400's and TI4600's) but they use parts that don't scale as high as the parts on the cards they sale under their own name.
I found this out when several programs kept calling my old PNY TI 4400 an MSI part such as SISOFT Sandra and WCPUID...I hope this helps, good luck.

alyssa

7 Dec 2003, 9:42am

So I copied the content of the zip file csdpmi4b.zip
to the disk with NVflash and the rom file on it.
Used the command
NVFLASH -fFILENAME.ROM

And....... everything went fine.
My GF4 Ti4200 has now the new bios inside!!

Thanks for helping me out, with this one.
Great forum btw, forgot to introduce myself..:banghead:

I have a problem with the xbios that has not been discussed here and I can not find any help info anywhere. I just bought and installed a Geforce FX 5950. It runs sweet as heck but there is room for overclocking!! Anyway, I have downloaded the xBIOS, version 1.03.520 as listed in this forum. I have all the other files downloaded and ready to go but my problem is that I can not even create the bios image for some reason. When I try to create it using xbios, it gives and error of "Bab PCI Header!", and I am assuming that the 'Bab' is a mis-spell meant to be 'bad'. No image gets created. When I try to get the image using dumpbios, the 'A' drive light stays on forever (watched a 2 1/4 hour movie and it was still going when I was done). I am using Windows XP, ABIT NF7-s Ver 2.0 motherboard. Any help would and will be appreciated. It's driving me nuts!!

Does anybody know of a different nvidia bios editor than the xbios? I can not find any info on the xbios error. I installed an old hard drive and installed winME on it and gave it a try. Same error. I installed the card on another computer, same error. It is either the card itself or the xbios program.

Supervisor

12 Jan 2004, 5:49pm

I finally got an image of my bios on my pny 5950 ultra card. I opened it in the xbios and the first screen shows all the info. The initialization tab shows '0' for all my clock speeds and it is blank for memory type. I am guessing that I should not flash this bios with this info. When I look in the general tab, the device id is 0333. When I click on the change button, I can not find my device id in it. I guess the 5950 is not yet supported?

Hello all

Sparkle FX5200DT running at standard as set from manufactor at 250 core 332 mem,having tested this via overclocking i know it is stable at 400 mem however....

I have exactly the same problem as kenerly i cant get the memory clock speed to stick,i know it said in the instructions to change the first line but my 1st line already said the setting i wanted(400) but my last line had the normal running setting(332) so i changed that,no joy rebooted and still on 332,2nd attempt i just changed the 1st line from 400 back to 400,no joy still 332,3rd attempt changed all lines to read 400 even though only 1 said 332,still no joy still running at 332.

have dumped the freshly uploaded bios to check that and that shows all mem clocks at 400 so i know it has uploaded but coolbits and powerstrip both report 332,how can this be when the only options in its bios is to run the mem at 400?

This starting to drive me mad,any help or ideas pls
Thx

Hi,
I have an msi fx5900xt, and my problem is that i read somewhere else how u could use leadtek bios on msi fine, so i tried the 5900 ultra bios for leadtek, the reason i chose this was cuz i tried nvflash to the msi 5900, but the thing is it would never flash, kept saying errors. Anyway i use the WFFlash, for leadteks, and it flashed the card, i went into windows, it wasn't recognising the card, just seda default monitor on, on the properties. Wehn i restarted my pc, tho at the start it said leadtek fx5900 ultra, anywa i decided to go back to my msi, as i had saved, but i cant, i tried flashing with the wFFlash and it wont as it isn't a leadtek bios, and the nvflash wont work, as it comes and says thres a mismatch. And then my friend told me to erase the bios, as it may not be letting me flash with the msi bios as the leadtek is on there, so i did, but it would still nto flash, and i couldn't keep my pc on forever, so it has no bios on the card, so i am using another card, although i have a pci card, and i hear that will help me flash the card, but i need to know how to do it properly, i have the bios, can soem1 please tell me what i should do exactly. Or if any knows what i might be doing wrong.

madmat

21 Apr 2004, 7:47pm

I'll tell you one thing you did wrong was after flashing the Leadtek bios on the card you didn't reinstall the drivers, you should have tried that first and then decided if the card was working from there.
Contact MSI and tell them the bios on your card got corrupted "somehow" and ask them if they have a utility to flash it from dos along with a new bios, try to get the FX 5900U bios and with the MSI card in your AGP port and the PCI vid card installed and hooked to your monitor reflash the bios following MSI's instructions.

Hey guys. I've got a serious problem with my ABIT GF4 ti 4600. Iv'e been trying to install a TT DragonOrb3 on it, using allready made 4 holes around the GPU. Ufcourse I had to drill it up a little bit, so they were 3mm wide and not only 2mm. At that point the card was still working perfectly. But later when i tried to put the DO3 on, the holes weren't matching, so i had to drill 'em up a bit more. But there was an accident, snd i drilled some more of the silicium in one of the holes. The hole widened and took some of the connections with it. At first it only seemed one, so i took the card to the neighbour and he soldered it, but obviously there were more of them in the depth, and so the card cannot be fixed. So i was thinkind of buying a broken 4400 and soldering the GPU and RAM grom my 4600 to 4400, and flashing it to 4600. What do you think? Would it work?

Hi SimGuy

Im new around here but this site is hopefully just the place for me to ask a question :)

I recently bought a Gainward 5900XT 256mb 1300 GoldenSample after reading reviews on its BIOS upgradability to a 5950Ultra.

Having pushed the core to 520 and memory to 950 stable, I am ready and confident that it can handle the 5950 Ultra's default settings.

I came across a 5950U Gainward BIOS for use with the 1300 Model.

After following the instructions on this site and using the bios from the other site (which other folks seem to have flashed successfully) I have run into problems.

I have managed to create backups of my current BIOS, but when I run the flash command (NVflash 4.46) of " NVflash.exe -f ***.rom" I get the following error:

" WARNING: ROM image file PCI vendor Device ID (10DE.0333), doesnt match chip PCI vendor, device ID (10DE.0332) "

Any ideas on how to solve this problem?

Thanks in advance!

SimGuy

25 May 2004, 11:40pm

Could you post a link to the Gainward 5950U BIOS for me?

AFAIK, the problem is that the BIOS you are trying to flash onto your Gainward card doesn't have the correct PCI Device ID set. It can be changed with a BIOS editor.

Either that... or you'll have to find another BIOS that perfectly matches the PCI Device ID, which may be very hard to come by.

Hey Kram

Just spent the day on the same problem as you have.
This is what i have found out so far.
Its a thing with the nvidia driver not the bios. If you un-install all your nvidia drivers and check the bios settings (i use aida32) the memory bus setting is as you have set in the bios. You can install the drivers again and the setting stays the same but as soon as you go into the device properties and set the screen size or anything for that matter and hit "apply" the setting reverts back to some default in the driver. I am using XP Home Edition BTW. I have mucked around in the registry but haven't found anything yet to fix it. Hope that helps a bit, sorry its not a solution

I am having the same "Bab PCI Header" problem. I have an MSI GeforceFX 5900 Ultra. I recently reflashed it to an FX 5950 Ultra. (MSI bios) Everything is great and the clock speeds were updated, however, I cannot do anything at all with X-Bios now. When i try to open the bios from the card it says "Bab PCI Header." I have no problems with it other than this. It isn't a huge issue, I would just like to know why I recieve this error and I didn't before with the original 5900 Ultra bios. Thanks.

I have a problem with the xbios that has not been discussed here and I can not find any help info anywhere. I just bought and installed a Geforce FX 5950. It runs sweet as heck but there is room for overclocking!! Anyway, I have downloaded the xBIOS, version 1.03.520 as listed in this forum. I have all the other files downloaded and ready to go but my problem is that I can not even create the bios image for some reason. When I try to create it using xbios, it gives and error of "Bab PCI Header!", and I am assuming that the 'Bab' is a mis-spell meant to be 'bad'. No image gets created. When I try to get the image using dumpbios, the 'A' drive light stays on forever (watched a 2 1/4 hour movie and it was still going when I was done). I am using Windows XP, ABIT NF7-s Ver 2.0 motherboard. Any help would and will be appreciated. It's driving me nuts!!

Hey guys I am new around here and have a BFG 5900XT and I was wondering what BIOS i can use to flash my card. I have heard that it is possible to flash my card to a 5950 or 5900 ultra but am not sure on the procedure. I tried using the tecqnique described in the first post but when running the nvflash it gives me some error about needing a zip file or something. Thanks for the help.

I am having severe bother with my DESKTOP after i used the MSI live update3 program to update the VGA drivers. As far as i know it has flashed teh GFX card, Nvidia geforce FX 5600(256) and it now no longer works... i get like checkered coloured lines allover display......

Does anyone know if i can sucessfully flash the original firmware drivers back onto this video card.... Cos if not i got a lot of saving to do to get a new one!

pop in a pci card boot in dos and force a flash to it(as long as you backed up the old bios).

Maybe I can help but maybe you make more wrong with my help as possible.
Its not my problem if you shoot your card with the following instructions.
I not responcable so if you flash its up to you.

Here almost all Bioses you can normaly use every manufactur Bios only importand that the kind of card is the right one you can not flash eg. gforce 4500 to gforce 4700 will kill it 100%

Recovery:
Download the right bios!
If you have gfx5500 os its: http://www.maxxon.com.cn/xsa/other/gfx5500.bin
no other one!!!
run flshaer tool in force or how it called mode if no other comands help!

The rest almost all bioses here:
http://www.maxxon.com.cn/xsa/xz8.htm

It might be lot action but if something going wrong you will need a epromer pic programmer etc... to make the small chip out and flash with it then solder back in.
Ther elot instructions in the net how to build a easy epromer, pic programer etc.. Electronical knowledge is required but it not to difficult if u follow the instructions almost parts below than 10 us dollar most expencive on it is the socket only. Cable to pc printer port (some can conect with max (maxim) ic (you get up to 5 pieces by maxim as free sample worldwide of this ic's) to parallel port)
Never flash the card if its not really needed or a newer version is out of the same type of card!
Backup always before u do anything!
Better use nvida bios editor to boost your card with the original bios dump it, go small steps higher in clock mhz. Never more than 10%

me too , but can i try reflash ?

in bios editor i do like this 270/400 too 360/510 can thies setings kill my card?

and than flash my card and card not responding i kiled it? :eek3: :ninja:

please help :(
Of course it will never go a screen on with it.
u put from 400 to 510 MHz!!!!
and 270 to 360 MHz!!!

Plane fall from sky, 100 mhz boostet impossible!!!
I told 10 % and test before with software tweaker not on hardware!!!
set +5 , + 10 MHz test in warm, hot conditions in case at least by playing game with need all graphic power 1h. If it work no stripes etc. try 3 to 5 Mhz more. Peak all together the chips can take never more than 50 MHz if u change the cooler with water cooler on it. If not chip burn inside out.

Read standard simple dos instruction how to work in ms dos command promt.
Forgotten DOS since win xp?
put dpmi on disk file
command promt: nvflash.exe /f mygf4600.rom
means file nvflash.exe and mygf4600.rom must be on disk!!!
Create disk use explorer create start disk boot disk format.
under explorer drive a or b put in a empty disk -> propertys -> format -> in dialog: hit on "Create an MS-DOS startup disk"
not quick format!
copy the needed files to the disk!

i did almost exactly what you wrote simguy, except for the fact that i put all the necessary files on one disk, including the bios and the flasher.
the problem is that i get an error message when i start the nvflasher, namely that the DPMI is missing or something like that, i forgot the correct message *sigh* ----> see edit

just wanted to know if you or anyone else here ever encountered that problem or at least could give me a hint what to do.

thanks in advance ;)

eeeeeeeeeedit:

1. i've now done used 2 disks, just to make sure ... same sh*t, different day ;|
but i've got a little more info on the error messages this time:
- when i enter nvflash /f mygf4600.rom, it says "Load error: no DPMI - Get csdpmi*b.zip"
- when i use dos4gw nvflash / mygf4600.rom, it says "can't load executive format for NVFLASH.exe

any ideas ? :(

edit #2:
should've remembered that i hadn't tried google yet ... i've flashed the bios successfully, but the problems remain (suppose i've damaged the card when i tried to install a different cooler)
