When I try to attach a Radeon RX 7800 XT as an eGPU using the Razer Core X Chroma to a Lenovo ThinkPad Z16 with both an integrated AMD Radeon 680M graphics and a discrete AMD Radeon RX6500M graphics card, it results in a BSoD. The error stop code is SYSTEM_THREAD_EXEPTION_NOT_HANDLED.
So, I am trying to add a third AMD Radeon graphics card. If I boot the computer with the Radeon RX 7800 XT connected as the eGPU, the external display is the only active display and there is an error on the bulit-in AMD Radeon 680M graphics in the Windows Device Manager. So, I guess the eGPU setup is working fine, but there is an AMD Radeon graphics card driver issue.
To test further, I tried to install a nVidia GeForce graphics card in the eGPU enclosure, and this setup works perfectly, as I thought it would, with both the built-in AMD Radeon graphics cards running the built-in laptop display and the external display running on the nVidia GeForce as an eGPU.
Should I consider bying a nVidea GeForce graphics instead???
My computer setup: Lenovo ThinkPad Z16 Gen1 (BIOS version 1.63), AMD Ryzen 7 PRO 6850H, Radeon RX 6500M (bulit-in discrete), AMD Radeon RX 7800 XT, Razer Core X Chroma eGPU enclosure, Windows 11 Pro (23H2 Build: 22631.2715), AMD Software: Adrenalin Edition 23.11.1 and the AMD Chipset Software 4.06.10.651.
