Hey Svet, I'm interested in your tool, but I have a very specific use for it I'd like to see if it can do.
I bought a fake GPU on eBay by mistake, and was promptly refunded after launching a dispute, but I'd also like the card to work as it's a shame to see it rot. The card is marked as a "GT 730", but definitely isn't.
Card looks like a Geforce GT 610 PCI in stats. The VRAM was spoofed to report 2GB, but physically only has 512MB, so it obviously quickly starts corrupting video data as it goes over its VRAM limit.
The device IDs and data have been modded to look like a GT 730 as well, though GPU-Z sees it properly. Additionally, the original clone modder messed up and made the card report a GF116 chipset, when it physically has a GF119-200-A1 chip on board, like the Geforce 605. The PCI and hardware IDs would need to be fixed for whatever this poor frankenstein card really is as well. I intend to make the fixed VBIOS public to help other victims of this scam as well and maybe prevent more e-waste.
I'll attach the VBIOS and pictures for review if you think it can be fixed to report correctly both its VRAM and actual GPU version, and how much you'd want to do it, assuming it's outside the scope of the utility you're offering.
I've included the GeForce 605 VBIOS I found that appears to be the only other reported card to use the GF119-200-A1 GPU revision. Note that the VRAM chips are designed to only run at a maximum clock speed of 800MHz, so it couldn't be used directly. Note that the card does actually have a 1Mb (128KB) SPI Flash chip, a Winbond 25X10CLNIG for reference, so it can handle the larger VBIOS in terms of memory size.
Thanks for taking a look, and have a great one!
