Dankclaw System Specs
Server Overview
Dankclaw is an AMD APU server for vLLM inference. The host runs Ubuntu 26.04 with an AMD Ryzen AI MAX+ 395 Strix Halo APU. The APU uses unified memory — CPU and GPU share the same physical RAM pool.

VLLM Relevance
- Unified memory eliminates separate VRAM limits. The GPU uses system RAM.
- ROCm reports 96 GiB GPU memory (overcommitted). Physical RAM is 30 GiB. vLLM sees 96 GiB and will try to use it. Set
--gpu-memory-utilization conservatively (0.80-0.85) to avoid OOM when the OS needs memory.
- Only 8 GiB swap. Set
--swap-space conservatively (4-8 GiB).
- ROCm 7.2.4 from AMD repos. vLLM ROCm support requires ROCm 6.3+.
- Python 3.14.4 is very new. vLLM ROCm wheels target Python 3.12. Use a Python 3.12 venv.
- Radeon 8060S falls under Ryzen AI MAX series (gfx1151). vLLM lists this as supported.
- 1.4 TB free disk space is ample for model storage.
libmpi_cxx.so.40 is missing from the system. Install openmpi-bin or provide a workaround for torch MPI dependency.
