I’m experimenting with Qwen3.8-27B using and I’m trying to figure out what the optimal configuration is for my hardware. I’ve tested two setups so far: Setup 1 — UD-IQ4_XS --override-tensor "blk.64..*=CPU" .\llama-server.exe ` -m "Qwen3.8-27B-UD-IQ4_XS.gguf" ` --ctx-size 131072 ` --parallel 1 ` --f…
