Flash your FX5900 to a FX5950Ultra! thanks to mitwg @ atomicmpc who translated the original article found here to english! ---------------------------------------------------------------------- nVidia used to hardwire all graphic cards with the correct BIOS so flashing cards like ATi wasn't possible... However, newly released information suggests that the NV38 (5950u) is simply a software rebadged NV35 (5900). From a simple flash, the 5900's Device id:0331 could be transform into te 5950's device id:0333 Now you may ask yourself about the 128MB vs 256MB question and how the 5900 has both variants while the 5950u only supports 256MB. Well unlike ATi's cards, nVidia chipsets do not store their buffer memory into its BIOS and rather, the amount of memory onboard is detected each time when then computer is booted. This means that even a 128MB 5900 can be flashed into a 128MB 5950u. This also applies to VIVO. Does this turn you on yet? Wait till the next line... The card tested on the website is a Leadtek A350 TDH-LX model... If you didn't know already, the LX version of the A350 TDH is a non-ultra version.Also it is a slower version then the original 5900, with clock speeds of 400Mhz core and 700Mhz memory speed. This card was flashed to be a Leadtek A380 TDH model which is the 5950 Ultra @ 475Mhz core and 950Mhz memory. After 1 hour of testing, GPUtemp is at 47degrees according to the Leadtek/nVidia readings. 6 cards are known and tested to work. These brands are : Leadtek's 5900 series including the slower LX model, Gainward's 5900 series, Elsa 5900 series, Insight 5900 XQ series and Rex Technology 5900 series. There are two flashroms currently available at the site. The Leadtek A380 5950U is available along with Gainward's 1800Ultra "Golden Sample" bios. Flash program is included in both files. I just looked at the source code of the homepage to obtain these links. If these don't work then head to www.3dchips.co.kr then click on the downdload section. the first thing you notice would be the huge amounts of bios roms available on the RHS of the page. nvflash: http://www.nvplanet.com/modules.php?...nload&cid=1 0 Leadtek: http://www.leadtek.com.tw/support/do...?pronameid=329 ftp://ftp1.leadtek.com/entertainment...80U%20BIOS.zip Gainward: http://www.3dchips.co.kr/main/downlo...pds_bios&no=55 Methods: This is a guide to flahsing ur 5900 card using the Leadtek bios. For gainward bios flash, refer to readme file included. Make a MS-DOS bootdisk 1.copy and extract all files within the zip file which contains the 5950u bios. 2. Reboot using the bootdisk 3. type 'a:\nvflash -b original.rom' this backs up your original bios 4. type 'a:\nvflash -f n5950u.rom -u -p' restart and you're done. if you do end up flashing your card, do not be surprised to see a Leadtek or a Gainward logo when you boot up even if your card isn't from these two brands. I did my Gainward 1200XP Ultra "Golden Sample" which defaults at 450Mhz 900Mhz to a 1800XP Ultra and it worked fine and I get about 5%~10% boost i think. I'm hoping Dx9.1 would bring the NV35 series the 60% boost that nVidia and microsoft promised... probably 6% i reckon... -------------------------------------------------------------------- this guide is provided "as is" we take no responsability if you screw up your videocard. |
some extra info from the Futuremark Forum Quote:
Extra guide http://www.3dchips.co.kr/main/gzrevi...&Page=1&no =1 As you already know, NVIDIA GeFORCE FX 5900 (simply “FX 5900”) and NVIDIA GeFORCE FX 5950 Ultra (simply FX 5950 UT) are actually the same model. Both of them uses the exactly same GPU core and they only has different level of power supplying systems and different GPU/MEMORY speed. (Different cooling solutions too) NVIDIA is used to lock the Bios Device ID in physical method from the way back. But 3DChips just have find a interesting fact that FX 5900 can be converted to FX 5950 UT by just simply replacing the BIOS data. Here’s how it works. You can change the FX 5900’s Device ID:0331 to FX 5950 UT’s Device ID:0333. This means your FX 5900 can be changed to FX 5950 UT in physical way. This is one of the things that NVIDIA’s users envied about ATI’s users. This conversion uses original FX 5950 UT’s BIOS instead of any kind of so called “tuned-up” ones. You must do this at your own risk and must be cautious. We used Leadtek A380 Ultra’s original Bios. FX 5900 128MB & 5900 256M models worked properly and VIVO capability is not necessary. Let’s convert a FX 5900 baby into a FX 5950 UT with no physical way that takes away your warranty~!!! Amazingly, FX 5950 UT model is so pricier than FX 5900. $200 worth of difference is seriously no joke for most of people but the rich ones. Fortunately, you can save a lot of money if you use 3DChips’ bios mod and this’ll convince you to do so if you’re interest in better frame rates. It requires some fortune to successfully convert your baby into a badass. Your FX 5900 must be able to handle FX 5950 UT’s furious speed, or your attempt will be turn in to a failure. The one we 3DChips tested is Leadtek GeFORCE-FX 5900 LX 128M. It’s not a normal one but the LX edition. NVIDIA's bios sets the memory speed automatically. (Auto detect) It means a BIOS for 128M model and 256M Model is eventually the same. There’s some peeps that says using the Bios for 256M edition can damage the card that uses 128M local Memory. But this ain’t an ATI’s Bios so don’t you worry about it. VIVO model are safe as well. How to update the bios- 1. Download the bios from 3DChips' download center. 2. Boot up your computer with your boot disk and safely back-up your original bios for just in case. 3. Type a:/nvflash -b original.rom and press ENTER key to store your original bios. 4. Type a:/nvflash -f n5950u.rom -u -p and press ENTER key to apply your new bios. 5. After you done all of them in order PROPERLY, restart you computer to apply the change you made. As we told you from the start, the most important matter is the fact that your FX 5900 must be able to handle FX 5950 UT's clock speed. If your FX 5900 is able to do so, you'll save a lot of money by using it as FX 5900 UT. But you must keep it in mind that your FX 5900 must stay out of excessive heat and stay strong. You need to remember one thing. This is a kind of an overclocking method and you're responsible for any malfunction or permanent damage of your VGA. Please keep it in your mind and be careful. 128M model worked properly and 256M model did so as well. Unfortunately, we couldn't test a FX 5900 SE model because it wasn't available in our test lab, so we bag you a pardon. |
looks like this is the new way to go :) did a flash from 9800pro to XT and it works to... |
be sure to read through the whole guide & take a look at the discussion thread @ futuremark before flashing your videocard, risks are involved but if you take the needed steps there shouldn't be a problem :) * back up your original BIOS * get a spare PCI VGA card "just in case" |
hey guys.... does this work on MSI 5900 ? |
from what I have read on the Futuremark forums some could make it work while other had to recover their original bios with the help of a PCI video card. |
hmm... thats not good enough... |

What file/bios should I use for myAlbatron 5900PV |
Hi shakenNstirred, thank you for your input, will update my first post asap, do you have links to older GF flashing guides/bios's? thanks in advance for your contribution |
http://msihq.designlab.info/thread.p...did=37755&sid= does it work with msi dont appear so least ways not with another makers bios |
Hi people, yesterday I flashed my Leadtek A350 5900 Ultra 256MB MyVivo graphic card to an A380 Ultra (5950) and it WORKED perfectly! Just followed the nice guide by the other dude and just like that in less than 5 minutes things were up and running. Obviously the risks with the RAM are lower when flashing the 5900 Ultra to the 5950 since the timings are the same I believe (2.2 ns) and the 5900 ultra by Leadtek is already equipped with an excellent cooling solution. Actually the new BIOS even improved the efficiency of my card as suggested by Leadtek on their Website! In fact the GPU core temperature dropped from an idle 47°C down to 38-39°C. These readings I have observed with an ambient temperature around 30°C as my heaters are both on in my room. Anyway I am curious to hear more people's experiences and yet as elementary as it may sound I simply would not RISK flashing the BIOS unless your card is within those listed. Of course it is always thrilling to try and experiment otherwise there is no fun and you will never know either! And with a PCI card on deck things can certainly be restored...... Cheers. |
Help Can anyone please email me or message me in aim. i have a Gainward GeForce FX 5900 Ultra 256mb. i wanted to flash it to a 5950 but i cant navigate the website on that link. does anyone have it that can send it to me please. Thank you for your time email: thernohn@msn.com aim name: thernohn |

Desperate to try this. :o f00ge@gmx.net |
I'm also having trouble finding the gainward bios - so if someone has it PLEASE email to me : dlr@12move.dk , or perhaps post a link to it... Thank you in advance |
How can you calculate the temperature for your card? I have a Leadtek Ti4200 and have wanted to know this for months. Thanks. |
I flashed my Leadtek A350 5900 128MB MyVivo graphic card to a 5950 a few hours ago, and all is working fine. Have ran 3dmark '01se and '03 several times and it worked fine. Have played Generals and Quake 3 (all at high detail) without any problems. As for the Temps the FX 5900 has a built in temp sensor. For a Geforce 4 I guess you would have to add your own sensor between the graphics card heatsink and GPU core to get some sort of temp reading. |
Ah ok, well thanks anyway. I was hoping it had a built-in sensor. |
Well, I've tried this twice on my XFX 5900 to no avail. I've tried with the leadtek BIOS and with a eVGA 5900 ultra BIOS. There's gotta be another XFX user out there that's figured this out! I wish XFX would release their BIOS rom's. |
|
I keep getting vendor id mismatches, etc etc.. I used a BIOS editor to get those to match but now I've got to a board chipset version mismatch (gainwards is a 3800 where my XFX is a 3502) .. the x-bios editor doesnt give me any where easy to find where this is so I'm screwed, for now anyways.. any good bios editors out there? =D |
I got a MSI GeForce FX 5600 256 MB, anyway to flash it to a better card? Maybe flash it to a 5600 Ultra at the least? I run Liquid cooling so not too worried about small heat problems unless it's just a massive heat gain... |
jmke: I ask you becouse you know a lot about this flash method. I have an asus fx 5900 128 Mb tv-out only (v9950). So can i use the leadtek rom (a380u.rom) to flash my vga bios? It is not a problem that leadtek a380u has 256 mb ram and vivo??? This is my big problem and my question. If it is work then just follow this: 3. Boot to DOS 4. change to the register with BIOS files. 5. Write: WFFLASH.EXE NM A380U.rom 6. Your video cards bios will be updatet. 7. Restart your PC 8. You maybe need to re-install the Detonator/Forceware Now, you habe a Leadtek Winfast A380 Ultra ! And probably everything going to be fine? Please answer me! THX!!! |
Hi Peace I found this guide on the Futuremark discussionthread, I have not tried flashing my soon to arrive FX5900 so I can't help you at this time, but as mentioned before, make sure your card is in the list before attempting this mod! |
I have flashed the Asus FX 5900 (non ultra) to FX 5950 Ultra (Gainward bios) and i have 100% with 2 of 2 cards! I have also succesfuly flashed the MSI FX5900 Ultra, non ultra, SP and FX version of the cards wich all of them were running 3dmark 03 for 9 hours now. I can confirm that you get a temp drop of about 8°C on all cards! This mod is simply fantastic!!! Gigabyte FX works also (tested) Asus FX 5900 works MSI FX's work |
thanks for the info urosv! |
I'm working at a Computer store so I have time to test this :) My brother changed his R9800 (non pro) to FX5950 Ultra today :) It's strange that the 2.8ns ram work at such speeds, maybe that's because the Ultras have higher latency memory... But so far I had 100% success with all cards. Will check the XFX model when i get one... p.s. I used this bios on all cards: ftp://gainward-ftp.de/lan/nvidia/bio...a/5950e400.zip |

no it wasn't meant to be like that... he changed the whole graphics card... He got a 5950 ultra for the price of a R9800... Ahm i'm not good in english so I'm having a pretty hard time expressing myself the right way... sory :) |
urosv:Tanks for the info. I have only the leadtek bios. Can you write here a working link for the gainward bios if it works correctly with the asus v9950. THX!!!! |
okok. I see. The link was there. My mistake. Sorry! LOL |
The most interesting thing is that my Asus 5900 was only partialy stable at 475MHz core and 950 MHz ram, and now it is 100% stable with 8°C lower temp. Is this good or what ?! :D |
Hey i have the A350 Leadtek 5900 Ultra TDH MyVivo card. I tryed to flash the BIOS but was getting a wierd error so i just updated the BIOS. Its picked up the card as a A380 now but i was wondering if having not flashed the BIOS would change anything? I see no changes in performance atm. Looking up the Geforce tab under display properties the BIOS date isn't the same as the A380's version. My version: 4.35.20.32 The version we downloaded: 4.35.30.32 Does this mean i haven't installed it right? |
What about the Albatron GeForce FX 5900EPV? What about the Albatron GeForce FX 5900EPV? What about this card? is there any chance? |
yes Oracle you didn't install it... Flash it with the link I provided... |
The fact is that all those cards are based on NVIDIA reference design - so I think all of them will work... Try it, but I would test the card if it overclocks to 475/930 MHz - because if it doesn't then i wouldn't flash it... BUT - my Gigabyte 5900XT would overclock max -> 450/840 and with the 5950U bios it works stable at 475/950. |
urosv: I downloaded the zip that you link to and flashed my BIOS with that. I then used the file 5950E400.ROM to update my BIOS with WFFLASH.EXE. My PC know thinks i've got a Geforce 5950 and its reading the BIOS version as: 4.35.20.35.08 Thats with NVidia's 53.03 Drivers installed instead of Leadtek's ones. My question is, have i done it right this time? And if so shouldn't i configure the card to the A380 Ultra? Wouldn't that work better with the card? I see no performance boost at all. Any help appreciated. |
