Below are the most common reasons for a worker to enter an unsupported state:
Mismatched GPUs
All GPUs within a worker must be of the same base model. While it's acceptable to mix different manufacturers (e.g. ASUS, Gigabyte, MSI), the GPU model itself must be the same.
- Supported: 4x RTX 4080s
- Supported: 8x RTX 4090s
- Unsupported: 3x RTX 4080s + 1x RTX 4080 Super
- Unsupported: 2x RTX 3070s + 2x RTX 3090s
Hardware Changes
Any changes to the number of GPUs after a worker goes online will immediately flag the worker as Unsupported. Currently, we do not allow altering the number of GPUs once a worker is active.
Too Many GPUs
Each worker supports a maximum of 8 GPUs.
GPU Drivers
GPU detection failures in our backend are often caused by driver issues; to reduce the likelihood of these problems, we strongly recommend using the following GPU driver branches for all workers:
- Windows: NVIDIA Driver 552.44
- Ubuntu: NVIDIA Driver 550.xx
