Hello,
I recently purchased an eGPU dock for my SER8 8845hs. According to my BIOS, 4G and Rebar are turned on, but for some reason, my graphics card (B580) cannot detect the Rebar. According to GPU-Z, my CSM is disabled, so everything should be working properly. I don’t understand what else I could be doing here. Is there a fix for this? Here are the GPU-Z screenshots. As you can see, Rebar is not enabled.
