Can I run Command R 35B on Nvidia GeForce RTX 3060 (12GB)?

Compatibility verdict VRAM threshold engine
No, not enough memory would not load

No. Command R 35B needs ~22.3 GB even at Q4_K_M, but Nvidia GeForce RTX 3060 (12GB) only has ~11 GB usable.

Needs ~22.3 GB Device usable ~11 GB

Needs ~22.3 GB even at Q4_K_M, but only ~11 GB is usable.

That figure is at a 4k context and moves about ±15% as context length changes.

The gap is about 11.3 GB: Command R 35B needs roughly 22.3 GB at Q4_K_M and Nvidia GeForce RTX 3060 (12GB) leaves only about 11 GB usable for a model. The lightest tracked hardware that runs Command R 35B is the Nvidia GeForce RTX 4090 (24GB) at 24 GB. See Command R 35B on Nvidia GeForce RTX 4090 (24GB).

Too big for Nvidia GeForce RTX 3060 (12GB)'s VRAM, but you could offload some layers to system RAM and still run it at roughly ~3 tok/s, far slower than a model that fits. How this is estimated.

FAQ

Can Nvidia GeForce RTX 3060 (12GB) run Command R 35B?

No. Command R 35B needs ~22.3 GB even at Q4_K_M, but Nvidia GeForce RTX 3060 (12GB) only has ~11 GB usable.

How much memory does Command R 35B need?

Nvidia GeForce RTX 3060 (12GB) does not have enough memory. At Q4_K_M the weights are ~20.05 GB; with KV cache and runtime overhead, budget ~22.3 GB at a 4k context.

What is the best tool to run Command R 35B on Windows?

LM Studio for a simple setup; Ollama (CUDA) for the most speed. AMD GPUs run via Vulkan/ROCm at roughly half CUDA throughput. NVIDIA is the smooth path on Windows.

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.
