No. Even at Q4_K_M, Gemma 3 27B needs about 21.4 GB, but the NVIDIA RTX 5070 has 12 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 gemma3:27bAt Q4_K_M it needs about 21.4 GB, so pick a GPU with at least 24 GB.
Run it in the cloud
Too big for the NVIDIA RTX 5070? Run Gemma 3 27B on a rented GPU instead.
Rent a cloud GPU by the hour. No upfront cost, stop any time.
