[SOLVED] Help needed to identify the correct bios to reflash fake gpu ?

[pacheko666]

Hello everyone!!! I recently picked this fake GT730 4GB DDR5 on a flea market for $1. I told myself this could be a nice chance to test my RPi spi flasher. I though I'll be able to find more info on the board, chip etc. to help me identify the real model of this card but I'm kind of stuck. If anybody can recognize it it will be awesome. My best bet so far following this guide https://www.techpowerup.com/forums/threads/fake-gpus-help-guide-please-stop-buying-them.284415/ is I'm looking at a GTS 450 1024MB DDR5 but I'm not definitely sure.
Thank you all in advance;
PIC0
PIC1
PIC2
PIC3
PIC4

this is GTS 450 revision 2 (GF116-200-KA-A1 ) but with 4GB ram hmm im afraid no normal bios would work as they have 1GB ram mapped

Hey @kerberos_20 thanks for responding. I run a couple gpu memory load test and it crashes always after using the first GB, so I assume its a 1GB. Ill go ahead and try install a GTS 450 rev.2 and will share the results

sure, if ram is faked then no problem with using 1GB ram bios

btw do you really need spi flasher? nvidia has flasing tools with which u can crossflash anything

Well not really, but on the past I found myself struggling with Nvflash and these fake cards. I definitely will try these nvidia tools first before going into surgery tho thanks

NVIDIA NVFlash with Board Id Mismatch Disabled v5.590.0 Download

This is a patched version of NVIDIA's NVFlash. On Turing cards, NVFlash no longer allows overriding of the "board ID mismatch" message through comm

Yes but no luck I already downloaded that version and won’t let me flash persistent GPU mismatch error. Please note how the device id it's all zeroes
GPU Mismatch error

Going into SPI flash I managed to read the content of the Pm25lq020b flash chip which is a 256K Bin file(EEPROM size), do we have any way to convert the 60K ROM file into the 256K BIN file needed to flash?

After days of frustration using Rpi and flashrom I decided to go with a different programmer: CH341A. Tested about 15 different bios for the GTS 450 1024 MB GDDR5 without any luck, some will show the classic artifacts on the screen, others won’t even allow to post. Earlier today I flashed this bios EVGA GTS 450 1024 MB BIOS aiming for a higher bios version and Voila!!! everything working perfectly with the card now. Drivers installed without any issues, stress tested with Furmark and other benchmarks and no crashes., temperatures a little over the hot side due to the stupidly cheap and clunky heatsink design the scammers are choosing.

congrats on reviving the gpu.

a gts 450 is similar in strength to a gt 730. Should still be useful for some very light gaming.
