Fake nvidia card maybe

[sisosaadi]

Hi
so i recently bought 2 Macy (a vendor i never heard of) GT 730 2gb for my two low end PCs one core 2 duo and a quad core the cards seems to perform well but crashes whenever i play a heavy game these games runs well with 60 fps average but one thing is after i play for 10 minutes sometimes near 15 minutes the games crash so i began looking for the issue and it appears that if i use more than 1GB of vram the games instantly crash and when i looked online i found that my cards might be fake and with no way to limit the vram unless i can find a way to edit the vbios so the cards report only 1gb of vram

so can anyone help me edit the bios rom files (i attached the file)

sorry for my english

Can you take a pic of the gpu itself? Include all the back stickers and get a decent shot or 2 of the heatsink. Those numbers in gpu z look legit. A heat issue may be causing the shutdown, when I had a fake gpu I bought from china the heatsink itself would detach from the gpu die because the springs holding it were too weak. After replacing them it worked fine but was definitely a fake card, the hdmi port didn't even work.

There's a bios expert here that can probably help you in finding one, he'll need the pics I asked for.

ok will do tomorrow its 3 am + i dont think its a heat issue cuz i monitored the gpu temps it never reached more than 58c i even underclocked it to the lowest possible

anyone ?

Since the cards are doubtful, you need to remove the heatsink and get a picture of the gpu die, clean and board shot front and back and a close up of a ram chip.

anyone ?

ok so here's some news i was able to flash another 730 vbios one that have 1024mb vram the card no longer crash BUT driver is acting up it says that i have two monitor attached but i only have one 1080p in the VGA port btw here's the vbios file i flashed https://www.techpowerup.com/vgabios/188541/188541 it has a higher clock but worked when i underclocked the gpu a little to 750
btw why my memory changed from samsung to Hynix ?

Hello, I have exactly the same card, I have never used anything that had to use so much ram, mine reaches 970 mb and crash.
From what I was looking at it may not even be the chip that shows gpu-z.
Today take the opportunity to clean it and renew the thermal paste.
The chips are samsung x8 K4B1G1646E - HCH9
according to the datasheet it is ddr3.
Take the opportunity to take a photo of the GPU, but it is partially erased, exactly where the model should be written ... LOL.
And I couldn't find information about the other chip data

I wanted to comment that I use the same bios of the user "sisosaadi" and it worked very well, without any problem, now there is no crash when loading twinmotion. The peak of ram rises to the top, and continues to function.
But, I also started to investigate, and I think the gpu is GF108 but it is a 1024mb GT430. Don't use that flash because you didn't want to search for the Nvidia drivers again.
But these are the graphics that I found.
And for similarities according to GPU-Z ... the GT430 has 8 matches

I collaborate with this information only so that if someone else happens the same, perhaps with this I can flash their graphics card without problems. Or at least closer to the reality of it

so , the problem is memory
( sorry but i gave mine away i have a GTX 650 for now ), the issue is that in my country the market is filled by these same gt 730 fake cards and the real issue is that they are not the same GPU chips
i fixed 3 by flashing bios to them but for each one i had to get a différent bios, mine was an Nvidia Quadro NVS 5400 a server gpu i think and i didnt find a bios for that card so what i had to do is to search for a fake bios for the same card but with only 1gb vram which luckly i found in the unverified section of the bios database of techpowerup so what i want to do now is to how i can modify a bios to report only the real amount of memory found in the card.

I used the bios that you have posted in the link, and it really worked very well, it is very stable, at least for the graphics card that I have. It is definitely the memory, mine has samsung chips, but installs the "hynix". the crash occurs when loading the ram. Verify it with GPU-Z reaches 970 mb and dies. They lie the ram memory to earn a little more money, and change the bios to install the "correct" drivers.

I had problems, could not open twinmotion, and that software in theory runs without a dedicated graphics card! But now that it has 1gb it is stable, although the temperature rises to about 68 °C .

Thank you very much for your post, it helped me a lot, and I hope it helps many people who have the same problem with these cheap "fake" graphics

I get a kick out of all these fakes cards based on fermi. The thermal nuclear reactor of gpus! I ran 2 gtx 480s, and had to use a 750w + a 800w psu to run them. One died, I still have
one that runs. One of the most inefficient archs made, and it still just keeps showing up.....

This is GTS 450 (GF106-250-KA-A1) with 1GB Samsung GDDR3.

@sisosaadi please submit a validation using gpuz: go to the validation tab and click submit, no need to enter anything. get me the validation id

edit: nevermind, i found a validation using your same card. it really seems to be the gf108 gpu, which has been used on a ton of cards: https://www.techpowerup.com/gpu-specs/nvidia-gf108.g82

This is GTS 450 (GF106-250-KA-A1)

GF106 looks completely different: https://www.techpowerup.com/gpu-specs/nvidia-gf106.g83

i opened the card before i gave it away i looked into the gpu name writen in the gpu die and when i looked in the gpu database it appeared to be a quadro NVS 5400

Finally I flashed the graphics card, with the GeForce GT 430, and it is much more stable, the temperature does not exceed 52 °C.
So I am practically convinced that my board had a GF108 GPU.
I had to re-install the drivers, but I'm happy the graphics run much better.

I used this bios https://www.techpowerup.com/vgabios/99389/nvidia-gt430-1024-100929

Thank you all for your opinions and comments.
