I have the Asus version that has the gddr but also does have the full 16 pipelines. Maybe you can use a bios of that card for comparison or maybe even flash it. I think it is the v9999gt gamers edition. Don't know how many shaders but i believe it is a full fledged 6800gt but with 128mb gddr to make it cheaper.

It also is an agp card.

thanks, I'll look it up online and try to flash my card with that bios. If it bricks, I can always reflash with the original bios.

Good luck, let us know if it works.

It did not. The card is still being detected as a 6800 LE - the only difference is GPU-z now reports it as an ASUS card.

Maybe there are jumpers/resistors on the card to define the model.

Like how moving / removing some smd resistors on newer cards can turn the card from a geForce to a Quadro? It's possible, but I can't find anything about it online, and I'm not willing to experiment/

Can't you just apply settings at startup in Riva Tuner options? That's what I remember doing with my Leadtek 6800XT AGP.

I did, and it works well. All extra pipelines and shaders successfully unlocked, and there is no artefacting even with the core overclocked to 400mhz - but I'm looking for a permanent solution.

If flashing doesn't work, and you aren't willing to find out if there's a resistor mod that can change it, then I think you're out of luck. Changing the resistor to change the ID of the card would be the only way to make the change permanent because the resistor will override all other changes. That's why your flash isn't working, the resistor isn't allowing it. That's how they kept you from turning a cheap GeForce or Radeon into a more expensive model. Have you tried modded drivers? Omega drivers is a good place to look for drivers that will unlock pipes. It will be as close to permanent as you're going to get without hardware modding.

I didn't say I don't want to do a resistor mod - just that I can't find info on it, and randomly removing SMD resistors off the back of the board can't be a good idea. If I knew exactly what resistor I need to remove I'd do it.

All I can come across is stuff like this: http://www.neowin.net/forum/topic/224694-turn … -ultra-extreme/

He offers some instructions on what resistors to remove, but the pictures are long gone so the thread is actually no help at all other than confirming tha fact that you can hardware mod the cards.

On Radeon 9600 the resistors are located on the chip itself. 9600SE vs 9600. Notice the difference in the bottom right corner:

Since you have both cards, you could compare core chips and find the right combination.

unfortunately both chips have the same resistor configuration. They are identical. The PCBs are also identical, sans the color and the GDDR3 on the MSI 6800.... this sucks.

Unfortunately it is in dutch and it is too technical for me to translate and (most of all) explain it. But here is al the info you need to modify your bios. Try a good translater i guess 🤣

It is stated that it is NOT needed to remove resistors and doesn't involve any soldering. Just changing settings to ignoring hardware masks and then editing some numbers.

You can scroll down to ''De 6800LE Hard-mod''

So the cores have identical resistor layout. The red one is a MSI 6800 GT with the full 16/6 pipes unlocked. The green is the Leadtek I'm trying to unlock.

Do they have the same resistor values as well?

This thread might be of interest to you:

There are a few threads witch describe the 6800le / nu to 6800 ultra resistor mod - unfortunately the much needed pictures of the resistors one needs to bridge are gone. I could not find pictures in any of the topic-related threads 🙁 This should have been preserved in places like Vogons for future reference.

I'm not sure measuring EVERY resistor on the back of the boards is feasible...

here's some pictures

UPD: tried that on Leadtek A400 LE. Didn't work for me. RivaTuner still shows 8/4 PS/VS even after flashing non-LE bios. Though you can permanently unlock units by applying NV4xBIOSSwUnitsMaskEliminator script to video bios from RivaTuner. I was only able to reach 6800 non-LE formula (12/5), volt modding to 1.4v didn't help against artifacts.
