Older versions of the MES firmware may cause abnormal GPU power consumption. When performing inference tasks on the GPU (e.g., with Ollama using ROCm), the GPU may show abnormal power consumption in idle state and incorrect GPU load information. This issue has been fixed in firmware version 0x8b and newer.
