Command R 35B needs ~27.1 GB VRAM. Tesla P40 24GB has 24.0 GB. With Q4_K_M quantization, expect ~6 tok/s.
Operating mode
Interactive favors responsiveness, while light API and scale-out lean harder on serving readiness. The fit stays the same, but the recommendation lens changes.
Current mode
Balanced
Balanced for general local use. Keeps the ranking neutral across personal and serving workflows.

Offload
10%
It fits through host-memory offload, and offload is the main reason performance drops.
CPU or host-memory offload is active
About 10% of the working set spills out of accelerator memory, which usually hurts latency and sustained decode throughput.
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.
Older PCIe generation
PCIe 3.0 is workable, but it compounds the penalty when you offload heavily or try to scale across multiple cards.
Remove offload with more accelerator memory
Prioritize a GPU or unified-memory tier that fits the whole model natively. Removing offload usually helps more than small compute gains.
Buy headroom, not only minimum fit
A slightly larger memory tier gives you safer context growth and makes the recommendation more future-proof.
Increase host RAM if you keep offloading
This setup may need roughly 2.4 GB of extra host RAM just for the offloaded portion, before OS and other tools.

Yes, Tesla P40 24GB can run Command R 35B with a B grade (Very compromised (needs ~2.4 GB host RAM)). Expected decode speed: 5.8 tok/s.
Command R 35B (35B parameters) requires approximately 27.1 GB of memory with Q4_K_M quantization.
The recommended quantization for Command R 35B is Q4_K_M, which balances quality and memory efficiency.
On Tesla P40 24GB, Command R 35B achieves approximately 5.8 tokens per second decode speed with a time-to-first-token of 33306ms using Q4_K_M quantization.
For coding workloads, Command R 35B on Tesla P40 24GB receives a B grade with 5.8 tok/s and 4K context.
On Tesla P40 24GB, Command R 35B can safely use up to 4K tokens of context. The model's official context limit is 131K, but available memory constrains the safe maximum.
Remove offload with more accelerator memory. Prioritize a GPU or unified-memory tier that fits the whole model natively. Removing offload usually helps more than small compute gains.
