Could you build this?
No Enabling a 32 GiB Resizable BAR on modded RTX 3080 cards involves GPU firmware, VBIOS and PCIe-level behavior, and hardware-specific validation. This is low-level systems work that vibe coding can't substitute for.
What it would actually take: A real version needs a deep understanding of the GPU's VBIOS, PCIe BAR configuration, and the driver's resizable BAR handling, probably through UEFI/option-ROM patching or a driver-level change. It requires low-level firmware and driver expertise plus physical test cards with memory mods, and failure modes can brick hardware.
