This setup is broadly balanced for this model.
Very little memory headroom
You can run the model, but there is not much room left for longer context, bigger batches, extra apps, or future model updates.
Buy headroom, not only minimum fit
A slightly larger memory tier gives you safer context growth and makes the recommendation more future-proof.

Yes, NVIDIA A40 48GB can run Command R+ 104B at Q2_K quantization (Runs with offload (needs ~1.4 GB host RAM)). The recommended Q4_K_M requires 72.6 GB which exceeds available memory, but at Q2_K it needs only 49.7 GB. Expected decode speed: 8.6 tok/s.
Command R+ 104B (104B parameters) requires approximately 72.6 GB at Q4_K_M quantization. On NVIDIA A40 48GB, it fits at Q2_K using 49.7 GB.
The recommended quantization is Q4_K_M, but on NVIDIA A40 48GB the best fitting quantization is Q2_K, which uses 49.7 GB.
On NVIDIA A40 48GB, Command R+ 104B achieves approximately 8.6 tokens per second decode speed with a time-to-first-token of 22429ms using Q2_K quantization.
For coding workloads, Command R+ 104B on NVIDIA A40 48GB receives a F grade with 2.9 tok/s and 4K context.
On NVIDIA A40 48GB, Command R+ 104B can safely use up to 8K tokens of context at Q2_K quantization. The model's official context limit is 131K, but available memory constrains the safe maximum.
