Asrock X570 Creator + NVIDIA Tesla A100 doesn't POST

I recently built a new workstation with an Asrock X570 creator motherboard + Ryzen 5950X CPU + Corsair AX1500I PSU, Titan V as primary GPU and a new Tesla A100 as secondary GPU. However the BIOS doesn’t POST with the A100 inserted; screen remains black and error code 07 appears. Does anyone have suggestions how to solve this problem or does anyone know a (better) x570 motherboard for an A100 GPU?


PS To be clear my setup works fine with only the Titan V.

Solved the issue. For anyone encountering this problem when installing Tesla GPUs as secondary GPUs in the future, make sure you set “Enable 4G decoding” to 1 in your bios!
