User details RTX 3090 Ti upgrade for local LLM inference

By PulseAugur Editorial · [1 sources] ·

A user details the process of upgrading a Dell Precision T5820 workstation with an RTX 3090 Ti to serve as a local LLM inference node. The guide covers specific BIOS settings, power supply configurations, and a seven-power-cycle boot sequence required for the PCIe link to train. It also provides instructions for compiling the llama.cpp software from source to optimize performance for the GPU, enabling it to run the Qwen3.6-27B model with a 262K token context window at approximately 42 tokens per second.

    Building llama.cpp from source on a Dell Precision T5820 with an RTX 3090 Ti (after seven power cycles)

    <p>I pulled a Quadro M4000 out of a used Dell Precision T5820, dropped in an RTX 3090 Ti, and turned the box into a homelab inference node running Qwen3.6-27B at 42 tok/s. Getting there took seven BIOS power cycles before the PCIe link would train. The Dell forum threads and the …
