AMD MultiGPU (not crossfire)

[u/ReasonableTaste5805]

Hello, I have a desktop PC equipped with an RX 9060 XT, an RX 7600, an MSI B550 GAMING PLUS motherboard, a Ryzen 7 5700 X3D, 32GB (4x8GB) of 3200MT/s RAM, and a 1TB NVMe drive; I also have an 850W 80+ Gold power supply and am running Windows. My current problem is that I cannot use the RX 9060 XT and the RX 7600 at the same time; when both are enabled via Device Manager, the system crashes after a while. I have no issues when using just one graphics card—whether it's the RX 7600 or the RX 9060 XT—but as soon as I enable both simultaneously, I eventually experience a driver crash. What can I do to keep both GPUs enabled at the same time without encountering driver issues, given that they work fine individually? Yes I asked to GPT but I think real personnes is alway's better.
