Installation steps (what did you do to get it all going?)
1) Followed guide on https://egpu.io/forums/deals/worldwide-aliexpress-us70-razer-core-x-chroma-mainboard-add-atx-psu-tb3-cable-for-lowest-cost-100w-pd-tb3-egpu/ to use a Razer Core v2 board from AliExpress with an old PSU and GPU.
Benchmarks (Include a CUDA-Z or AIDA64 bandwidth pic. Optional: Valley, 3dmark, noting if it’s on internal/external LCD )
TODO.
Comments (eg: how has the eGPU improved your workflow or gaming)
Still seems a bit flaky at the moment. The kernel occasionally has issues adding the PCIe device on attach (dmesg --follow is very helpful), and hot unplugging has crashed the kernel at least once, meaning I tend to plug the board in before booting. Will update as I do more testing.
