A simple DGX Spark setting to reduce overheating
DGX Spark can run too hot in summer conditions and freeze during work. Lowering the NVIDIA speed with can reduce heat. The example setting is `sudo -lgc 0,900`, which limits the clock to 900MHz.
After this change, the fell from 85C to 60C, and the overheat lockups stopped. Extra fans are another option, but reducing the heat made by the machine itself can also improve stability.
Key points
- DGX Spark can freeze when it gets too hot.
- `sudo -lgc 0,900` limits the clock.
- One setup dropped from 85C to 60C after the change.
- The setting stopped overheat lockups in that setup.
- This can help workloads run more reliably.
