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 think this is the good bios.

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:
