I'm trying to install an NVIDIA Tesla V100 32GB PCIe card for use with Ollama, but the system never detects it in BIOS or Windows. The NVIDIA driver installer also stops with "no NVIDIA cards were found." I've reseated the card, checked its power connection, changed the relevant BIOS settings, and even tested a second V100 with the same result. My system has a Ryzen 7 5700G, a Gigabyte Eagle WiFi 6 motherboard, 96GB of DDR4 memory, Windows 11 Pro, and a 1000W power supply. What hardware or firmware compatibility issue could prevent the card from appearing at all?

Since the card isn’t visible in BIOS, this is probably not a Windows driver problem. Check PCIe compatibility first: update the motherboard BIOS, enable Above 4G Decoding and Resizable BAR, and try another full-length PCIe slot if available. Tesla cards are intended for workstation or server platforms, so consumer-board firmware compatibility can be hit or miss.
The power supply should be adequate at 1000W, but make sure the V100 has the correct auxiliary power connector and that the cable is connected directly from the PSU rather than through an unsuitable adapter. These cards can draw a large amount of power during startup. If two cards behave identically, the motherboard, power wiring, or firmware is more likely than both cards being faulty.
Be careful to distinguish a genuine PCIe V100 from an SXM2 or SXM3 module mounted on an adapter. SXM versions are not standard PCIe cards and require specialized server hardware. Even with a real PCIe model, Tesla cards may need a platform that supports their large BAR memory mapping; enable Above 4G Decoding and Resizable BAR, and confirm the exact card model and PCIe slot wiring.
This is the PCIe version rather than an SXM module, and the system is using a 1000W PSU. The card still isn’t detected before Windows loads.
I’ve already enabled the relevant BIOS options and tested more than one server motherboard, but the card still doesn’t appear.
