MoBo, CPU, RAM suggestion | I'm terrible at guessing hardware | no gpu

This Reddit thread from r/ollama features a user seeking community recommendations for motherboard, CPU, and RAM components to build a system optimized for running Ollama locally without a dedicated GPU. The discussion likely centers on CPU-only inference considerations, where memory bandwidth is the most important factor, with more memory channels yielding better performance , and modern CPUs such as 11th-gen Intel or AMD Zen 4 are preferred for their AVX/AVX2/AVX512 support, which accelerates the matrix multiplication operations used by LLMs . Community members likely advise on RAM capacity, with 8GB as an absolute minimum for 3B models, 16GB for 7B models, and 32GB for 13B models , helping the user select hardware that balances cost and usable model size for a GPU-free setup.
