Can someone figure out what GPU is this?

[Raffa]

Hi, so I bought a FAKE graphics card 2 months ago, I was wondering, if I can flash a correct BIOS on it, I can still use the GPU without artifacts on my screen if the video memory exceeds 965 MB
So I opened TechPowerUp GPU-Z the other day, and I found out that the graphics card I bought was "FAKE". It says its GPU is G92 and the revision is A2... Alright, now I thought I knew the right BIOS to flash... Tried to flash a 9800 GT BIOS, didn't work. Tried 8800 GT and GTS, also didn't work. Tried a GTX 260M BIOS, STILL didn't work. At least I backed up the BIOS before flashing... Tried a GTS 250 BIOS... STILL DIDN'T WORK.
So I opened the heatsink and there's no "G92-xxx-A1" on it. There's the serial numbers and the NVIDIA logo but that's all. All I wanna know is what GPU is this... and once I found the correct BIOS I will try to flash it on my graphics card... Also, when I flashed any of the BIOS I tried, it doesn't show anything on the screen.

Wouldn't surprise me if it was a GTS 450. Those things are a plague

Wait... Is there a G92 version of a GTS 450? Because I tried to flash a GTS 450 BIOS on it, but it's still giving me black screen after hitting the power button :/

So what card did you think you bought? Could you also upload a GPU-Z screenshot with the Bios that came with the card.

 

[Caring1]

Hynix datasheet confirms it has 1GB of DDR3 Vram.
Awaiting GPU-z screenshot.

Looks like a G92B die, which is a die-shrink of G92.

Need a GPU-Z screenshot to get the info we need.

It could be a GTS 250 (maybe a different variant than the one you tried to flash) or a GTS 240.

Alright, here it is and the "G92.zip" is the BIOS that came with the card

Can you measure the die area in mm?

This will help to confirm what silicon it is. IMO the power delivery and PCB aren't sufficient for a G92 of any description, that looks like the kind of hardware that could support a G94 though....

Those are 1Gbit (128MB) 1400MHz GDDR3 chips so there's 1GB of VRAM on the board.

I know that older Fermi and Kepler GPUs have small SMD resistors on the board that tell the computer what the PCIe Device-ID is, could it be that they have modded the PCB in order to show the wrong one? I don't know if Telsa used this method, but if it did that could explain why it isn't accepting the VBios. Just a thought...

...I don't know if Telsa used this method...

Some quick research shows that this does not appear to be the case...

Alright, so I measured the GPU die using a ruler and here's the results:
24 mm diagonally
17 mm vertically & horizontally
I also posted a picture of the measurements:

 

[Supercrit]

I don't think any official bios will work on this, it has 9600GSO's core count, 128bit instead of 256 or 192, 2GB of ram which probably not any official G92 cards had (probably fake because artifact before 1GB), this could even be a mobile GPU soldered on it, truly Frankenstein monster.

I seen to recall 128-bit 9600GSO's existing. I remember because at the time, they were too be avoided in favor of the 192 bit version, which also had more shader units or something.

Assuming that it is 1GB GDDR3, that it's G92, and has no PCIe Power connector (as images indicate) it could be a GeForce GT 330 OEM

The die is clearly a G92B judging from the placement of the SMD components. That narrows it down. It's G92B, with 1GB GDDR3....

Update: No SLI Bridge on PCB indicates OEM model or very low end, it also looks like it has HDMI which was not very common on AIB partner G92B models.... I'm stuck I have no idea

 

[adnpst]

My best guess is that it's a 1GB variant of this GeForce GT 330 OEM, I/O matches, bus-width matches, die matches, power rating matches, but I can't find any 1GB examples of a GT 330 with a G92B die so maybe not. Good luck trying to find a VBios of this model to try

Alright, so I measured the GPU die using a ruler and here's the results:
240 mm diagonally
170 mm vertically & horizontally
I also posted a picture of the measurements:

That's impossible, 24cm and 17cm.

You mean 24mm diagonally and 17mm vertically/horizontal, seems stil too big IMO...

Oh yeah, it is 24mm and 17mm... My mistake...

Ok, so I tried to look at my GPU die and different G92 die on the internet, what I found is very interesting... Yes, it seems like its a G92B because there is a "B1" in the GPU die itself. So maybe it is a G92-xxx-B1 with 1 GB GDDR3 VRAM and 128 bit bus width... Also, I googled "1019B1 GPU" and went into the "Images" section and immediately got a "G92-751-B1" GPU die... This might be incorrect because some websites don't have 1019B1 on them.

I'd say try the BIOS for the 1GB GTS 240 OEM. The bus width doesn't match, but since GPU-Z is misreporting the GPU die and the memory amount, maybe it's misreporting the memory bus width too.

But hold your horses everyone. I wouldn't put a 256-bit card's vbios on that, as it has 4 chips per side, so it's truly a 128-bit card physically. A 256-bit one would probably have all chips as a "strip" like 5900/6800/7800/8800(G92) etc has.

I can't find any G92B cards with 1GB of GDDR3 and a 128-bit bus.

I'm thinking it could maybe be a 512MB card that just happens to have an extra 512MB on the PCB.

The memory modules are 1Gb GDDR3 ones from Hynix, and there are eight of them, each with 32 banks of 32Mb.

I don't exactly know how bus width works, but I do know that having eight chips, each one with 32 banks, totals 256 banks. Please correct me if I'm completely wrong about a correlation between the number of memory banks and bus width.

My wild guess is that it's some weird Chinese-only card which has been flash with a fake bios with that weird configuration.

I'm also not expert at bus widths, actually now that I think about it, I'm not sure anymore is it 128-bit or 256-bit..

I mean a 256-bit card could have its chips on both sides. Like good ol' Radeon 9700 Pro for example.

Based on the 17x17mm die size it probably is actually a G92 / G92a on 65mm. Actual exact sizes of G92 are 17.7mm x 18.3mm, so it's probably an 8800GT/9800GT (the exact same card with different names).
It also looks exactly like a G92, right down to the layout of the SMTs between the die and the edge shim.

• It's a close match for the die size which we know because you measured it.
• It's a close match to the 600MHz clock and GPU-Z measures that rather than reading the BIOS for it.
• Your card has 8 DDR3 chips (4 front, 4 back) and each chip has a 32 bit interface so it's almost certainly a 256-bit bus, making it a match for G92.
• The shader clock (measured at 1375MHz) is actually a match for the 9800GT Green Edition
• The memory clock of 650Mhz is within the 500-900MHz range that was used for the Green Editions.

Also, just because it has 1GB of DDR3 fitted doesn't mean it's going to work with 1GB. There was a 9600 GSO 512, for example, which was harvested from G94 chips with defective memory controller. All of the DDR3 was populated because the defective controller varied in location between dies and it was easier/cheaper/faster to do that and disable half the DDR3 in software than it was to make multiple permutations of the PCB with only half the RAM installed in various different ways.

I'd try some 1024MB 9800GT Green Edition BIOSes first - the ones with 550/1375 clocks and 700MHz memory. If none of those work try the 512MB variants.

 

[Caring1]

Is there a board number screen printed on the PCB somewhere?
Any markings under the crappy Q code sticker?

Forget the G92 or G92B, that Die size is too big for what you have.
Closest I could find is the GT 340 OEM with a 144mm2 Die size which also came with 1GB of DDR3 128Bit.

Judging from the way people are struggling to ID the card as it appears to have conflicting details, the whole card could be some kind of frankenstein monster that doesn't officially exist anywhere, especially if that's a mobile GPU on there. If this is true, then editing that dodgy BIOS will be the only fix. Expert knowledge would be required for that and not the kind of information you could find on a forum.

This card is a real PITA for sure. Scammers really know how to screw over their customers victims.
