No. Even at Q4_K_M, Qwen3 30B-A3B needs about 19.9 GB, but the NVIDIA RTX 3080 10GB has 10 GB usable. You could offload some layers to system RAM, but it will be very slow.
Run it on a rented GPU
On a cloud GPU with enough memory, the same command you'd use locally works:
ollama run qwen3:30bAt Q4_K_M it needs about 19.9 GB, so pick a GPU with at least 24 GB.

Frequently asked questions
Can NVIDIA RTX 3080 10GB run Qwen3 30B-A3B?
No. Even at Q4_K_M, Qwen3 30B-A3B needs about 19.9 GB, but the NVIDIA RTX 3080 10GB has 10 GB usable. You could offload some layers to system RAM, but it will be very slow.
How much VRAM does Qwen3 30B-A3B need?
About 19.9 GB at Q4_K_M with 8,192 tokens of context, and about 62.4 GB at full FP16 precision.
How fast is Qwen3 30B-A3B on the NVIDIA RTX 3080 10GB?
It does not fit in the NVIDIA RTX 3080 10GB's memory, so most layers would run from system RAM and generation would be very slow.
