What quantization should I use for DeepSeek-R1 on a GMKtec EVO-X2 Ryzen AI Max+ 395 128GB?

Q4_K_M is the highest-quality quant that grades B or better on this hardware with llama.cpp at 8K context; the per-quant table on this page grades all 4 available quants.

Can a GMKtec EVO-X2 Ryzen AI Max+ 395 128GB run DeepSeek-R1?

No. DeepSeek-R1 needs 405.6GB at Q4_K_M with llama.cpp and 8K context; the GMKtec EVO-X2 Ryzen AI Max+ 395 128GB has 128GB of unified memory (~75% GPU-addressable) (95.5GB usable) — it does not fit, even with CPU offload.
