Can I run Nemotron 3.5 Bolt E4B on Nvidia DGX Spark (128GB)?

Compatibility verdict VRAM threshold engine
Yes, it runs GPU accelerated ~24 tok/s est.

Yes. Nemotron 3.5 Bolt E4B runs on Nvidia DGX Spark (128GB) at Q4_K_M (~8.9 GB of ~112 GB usable).

Needs ~8.9 GB Device usable ~112 GB

Runs at Q4_K_M using ~8.9 GB of ~112 GB usable. You have room for FP16 for higher quality.

That figure is at a 4k context and moves about ±15% as context length changes. Nvidia DGX Spark (128GB) leaves ~103.1 GB of headroom, room to step up to FP16 for higher quality.

Running cost · estimate

Power & economics est.
Power draw

Electricity / 1M tokens

Pays for itself after
~15,381M tok

At ~$0.15/kWh and the estimated ~24 tok/s, a million generated tokens costs about $0.24 in electricity. Versus a hosted API at ~$0.5 per million tokens, the ~$3,999 Nvidia DGX Spark (128GB) pays for itself after roughly 15,381 million tokens, so local hardware is mostly a fixed cost, not a per-token one. TDP is the peak draw, so this is an upper bound. Assumptions.

FAQ

Can Nvidia DGX Spark (128GB) run Nemotron 3.5 Bolt E4B?

Yes. Nemotron 3.5 Bolt E4B runs on Nvidia DGX Spark (128GB) at Q4_K_M (~8.9 GB of ~112 GB usable).

How much memory does Nemotron 3.5 Bolt E4B need?

Nvidia DGX Spark (128GB) has room to spare. At Q4_K_M the weights are ~7.37 GB; with KV cache and runtime overhead, budget ~8.9 GB at a 4k context.

What is the best tool to run Nemotron 3.5 Bolt E4B on Linux?

Ollama for a simple setup; vLLM for the most speed. vLLM shines for multi-user serving/throughput. For a single local chat, Ollama or llama.cpp is simpler and lighter.

Weights are measured from GGUF files; KV cache and overhead are computed, so totals can vary ~15% with context and runtime. Any tok/s is a bandwidth estimate. See methodology.
