Current Situation:
- Card works, but suspected non‑original VBIOS.
- Memory initialization and bus width not correct with tested BIOS files.
- Already tested 3 different VBIOS versions from TechPowerUp → same result.
- Avoiding repeated flashing to prevent hardware stress.
Actions Taken:
- Checked PCIe voltages and signals PEX_RESET#, CLKREQ#, REFCLK → all OK.
- Flashed VBIOS with partially compatible versions → card detected in Windows, driver installed, but VRAM reported incorrectly.
- Physical inspection of PCB and VRAM → all chips present, no visible modifications.
