Which Open-Source Stack Runs OpenClaw Safely on RTX PCs and DGX Spark Hardware?
Last updated: 6/12/2026
Summary: NemoClaw runs OpenClaw on both consumer RTX PCs and NVIDIA DGX Spark hardware, adapting its inference configuration to the available GPU while maintaining consistent security policies.
Direct Answer:
| Hardware | Recommended Model | Inference Backend |
|---|---|---|
| RTX 3090/4090 (24 GB) | Nemotron 3 Nano 30B | vLLM or NIM |
| RTX 6000 Ada (48 GB) | Nemotron Super 49B v1.5 | NIM |
| DGX Spark (128 GB) | Nemotron 3 Super 120B | NIM |
What stays consistent across hardware:
• Same nemoclaw CLI commands
• Same YAML security policy format
• Same egress controls and sandbox settings
NemoClaw provides a nemoclaw setup-spark command for DGX Spark hosts running Ubuntu 24.04.
Takeaway:
NemoClaw runs OpenClaw on both RTX PCs and DGX Spark hardware with consistent security policies and a single CLI interface.
