|
+To support GPUs older than Compute Capability 5.0, you will need to use an older version of
|
|
+the Driver from [Unix Driver Archive](https://www.nvidia.com/en-us/drivers/unix/) (tested with 470) and [CUDA Toolkit Archive](https://developer.nvidia.com/cuda-toolkit-archive) (tested with cuda V11). When you build Ollama, you will need to set two environment variable to adjust the minimum compute capability Ollama supports via `export GOFLAGS="'-ldflags=-w -s \"-X=github.com/ollama/ollama/gpu.CudaComputeMajorMin=3\" \"-X=github.com/ollama/ollama/gpu.CudaComputeMinorMin=5\"'"` and the `CMAKE_CUDA_ARCHITECTURES`. To find the Compute Capability of your older GPU, refer to [GPU Compute Capability](https://developer.nvidia.com/cuda-gpus).
