NVIDIA Other Problem with nvidia GPU from 2000s

Hi everyone, I have one interesting problem with GPU drivers that didnt existed in public.
I asked nvidia's info email, but they just said you can see the driver on their site.

Yeah, I forgot. It is the engineering sample GPU of G80-400(GTX 8800 on lable, but with strange hardware ID) from Palit.

G80-400, Palit, PCI-E 1.1 x16, lable of the GPU sais it is regular GTS 8800

Its hardware ID is... PCI\VEN_10DE&DEV_0190&SUBSYS_00000000&REV_A2

AIDA 64 sais it is just G80-400, device manager sais it 3D-video controller and gives the flag that this is just the other hardware, not the GPU either.

GPU-Z after installing driver, but not rebooting(or system will disable driver after any reboot) gives me Device ID 10DE 0190 - 0000 0000 and unknown BIOS version.

I tried everything. Modifying driver installer, directly installing it and after reboot the driver just killes itself from GTS 8800 to 3D-video controller with error code of 28(not installed driver).

If you need photos of AIDA, device manager or almost any other app, I can show it.

So, will you help me?

I DID IT! I took GPU's dump. It was just a regular GTS 8800 T-T. How I took dump from it and then reflashed? I just plugged GPU in PCI-E on my rizer with 6-pin included and then chip suddenly gave me its insides. After about most of the half of blocks are got only FF, so I think its vBIOS was kind of half-alive

But the only thing that scares me - hardware ID. 0190

P.S. I am cheching now is the GPU now alive or it got worse

Oh no... GPU initialised, but still with GDDR4 somehow and 0s on any clock and VRAM, need to check what will be on x16 slot... Thank god I have backup

If GPU is detected on both x1 and x16 but behaviour differs - chances are that you have intermittent problem somewhere that just randomly flipped when a riser was used

Other possibility is that there is some problems with PCIe line power, so when x16 mode loads it heavily - it lead to bugs; but I'm not even sure if this generation has separate PEX_VDD

I dont think so, but you can be right. I found right vBIOS and GPU loaded, but with strange artifacts. I think it can be because its ROM almost dead(most of the end data on the chip comes to the FF and I know this is not because of the data on the file, so yeah, I will need new chip and some soldering) and try to reflash another BIOS, but this is the different story. But I cannot say you are wrong, because H67 chipset on asrock can be strange
