Every build
| Build | Quantization | Download | RAM needed |
|---|---|---|---|

| 27b-it-q8_0 | q8_0 | 29 GB | 36 GB |
RAM figures are working-set recommendations: when GPU memory is short, the runtime spills to CPU and system memory instead of failing.
Install it
Pair a computer with idapt and install Gemma 3 27B from the model page: the local engine bootstraps itself, pulls the build you pick, and streams progress. Or pull it directly:
ollama pull gemma3:27b-it-q4_K_MFrequently asked
How much RAM do I need to run Gemma 3 27B locally?
The smallest Gemma 3 27B build runs with about 24 GB of system RAM; the largest needs 36 GB. RAM is the binding requirement: when GPU memory is short, the runtime spills to CPU and system memory instead of failing.
Which quantization of Gemma 3 27B should I pick?
Start with the default 27b-it-q4_K_M build: a 17 GB download that wants about 24 GB of RAM. Smaller quantizations shrink the download and memory needs at some cost in output quality; larger ones do the reverse.
Do I need a GPU to run Gemma 3 27B?
No. A GPU with enough VRAM makes generation faster, but Gemma 3 27B runs on CPU and system RAM alone. Whether a build fits is decided by RAM; the GPU only changes speed.
How big is the Gemma 3 27B download?
Between 17 GB and 29 GB, depending on the quantization you pick across 2 available builds.
Can idapt install Gemma 3 27B for me?
Yes. Pair a computer with idapt and install Gemma 3 27B from this page: the local engine bootstraps itself, pulls the build you pick (ollama pull gemma3), and streams download progress. Local runs are not billed.
