Fake GTX 560 3GB DDR3?

[Marlon5775]

Hello everyone,

I found this GPU in an old PC and wanted to see if it works. The GPU seems to be functioning, but GPU-Z and HWiNFO both indicate that it might be fake. After doing some research, I found that there is no GTX 560 with 3GB of DDR3. So I'm wondering what this card really is. I also did an Memory Test the results are below.

I took some pictures of the die and the memory chip. Under load, the memory chips were as hot as 95°C/203°F.

I hope someone can help me identify this card.

Thanks in advance!

GF116 is Fermi which are GTX 400/500 or GTS 400/ 500 or GT 400/500 series parts, definitely a deep fake

It is for sure a 3GB card due to the 2Gb chips used. 2Gb= 0.250GB * 12 = 3072MB

I used Micron's FBGA decoder to find the full part number below.

Thats a refubrished GTX550Ti 3GB, with specs identical to the card reported here in 2011

It is refubrished from the chip produced in 2012.09 (maybe the laptop/quadro) with newer 2019-produced micron memory.

Besides the questionable stability/longetivity - it should work identically to that 550Ti.

The faking is identification, that was faked from 550Ti into 560. Can be just ignored. Since it works -I don't recommend trying to tinker with VBIOS - maybe it has some timings special for this micron memory and would not work with any other VBIOSes, maybe even useful to upload it with GPU-z button mentioning in the comments that its for GF116 chips with 12 ICs of Micron Z9MHN memory

The plot thickens.

The bios version above states for a gf104 pcb

NVIDIA GTX 560 VBIOS

3 GB DDR3, 900 MHz GPU, 533 MHz Memory

Anyways from what I see it should be a GF116 on a GF106PCB from bios files i looked up.

What manufacture should I choose? And as model name just GTX 560 3GB?

 

[StViolenceDay]

While submitting VBIOSes from GPUs without easily recognized model - enter the values present on various stickers/gpu board - this may be useful for others searching for VBIOS based on their labels

So, I'd suggest:

• manufacturer: "NVIDIA"
• model name: "V560N-3072"
• and chip labels in additional comments "GF116-like N13-750-A1, Micron Z9MHN"

It says that it was already uploaded by someone

So, its https://www.techpowerup.com/vgabios/159529/159529

Quite unexpected that refubrish produced with 2019-year memory would work with 2014-uploaded VBIOS, but it's the fact! Seems that VBIOSes are very interchangeable between GF104/GF116.
