GPU BIOS experts.... need your help!

[K404]

I have a(nother) problem with my 9800GX2. I flashed the BIOS and I thought everything was ok.

 

Now, when I boot, I get an error with PCB1. GPU-Z comes up as below:

 

 

 

 

Heres GPU-Z for the 2nd PCB.... no problems here

 

 

 

 

 

 

I have tried flashing the BIOS and in nVFlash, it sees the different BIOS revisions fine, so at *some* level, the data is going onto the BIOS chip.... AND.... when I install/reinstall drivers, it sees the BIOS revision on PCB1 before the restart..... it just falls apart when I restart.

 

 

 

 

Does anyone have any ideas whats going on? Voltages are being supplied to the card as expected.

 

 

Thanks!

Did you flash all three parts of the BIOS? updating GX2 BIOSes is more complicated than a single card.

[K404]

Yup.... well.... I'm *quite* sure

If you can confirm (or deny!) what i've done is right, that would be great If the BR-04 BIOS was wrong, I would expect the second card to suffer, not the first??

Anyone?

Revision of your first VGA is FF is correct that info ?

 

Could be that Bios version is incorrect ?

 

Flash with correct Bios for that VGA and I think that works well.

 

The same Bios for your two cards.

 

I think that you save second Bios and flash on to first card that works well.

I quote Andre Yang :

 

new NiBiT and nvflash worked perfect at 9800GX2.

 

This card is different from 3870X2 because there are 3 bios at this card. BR04 Bridge bios, Core 1 bios and Core 2 bios.

 

 

Save under DOS

 

Core1

nvflash -b -i1 xxx-1.rom

 

 

Core 2

nvflash -b -i2 xxx-2.rom

 

 

Next, using NiBiT 3.9 edit and flash under dos, too.

 

Flash bios under dos

 

Core1

nvflash -4 -5 -6 -i1 xxx-1.rom

 

Core2

nvflash -4 -5 -6 -i2 xxx-2.rom

It works, tried it already.

Card is dead, but not because of this

Hey bro! The revision shows up as "FF" because the card is not being identified properly. The BIOS I am using are ok

 

Gamer... that's the process i'm using, but i'll try in Windows.

 

 

I've started wondering if it's a hardware death and it's just happened at a time that makes me think it's BIOS. I've not even removed the stock cooler

Check if you have picture on both DVI outputs, if not, one is dead.

 

Time to bake

[K404]

I thought that for single monitor on 9800GX2, the second port (PCB2) HAD to be used? I can't remember ever getting a pic from the port on PCB1, on ANY of the cards i've owned over the years?

 

(*i'll try it though!)

[Gamer]

You should have picture on both DVI's, I'm sure of that.

[K404]

No picture on the DVI of PCB1

 

Deffo made progress though..... let card boot to Windows (modded 169.21) let the PCI-PCI bridge drivers install, but not update the driver..... GPU-Z started showing the right details for PCB1 for around a minute, then the screen started artifacting.

 

Card was hot when I powered off.

 

Have taken a heatgun to PCB1, lets see whats next

 

 

 

EDIT: Heatgun: 1, artifacts: 0

 

Next problem... same as before "device cannot start" ......
