错误 1997531
- #define nvmlClocksEventReasonGpuIdle 0x0000000000000001LL
-
GPU 上没有任何程序运行，时钟降至空闲状态
注意此限制器可能会在以后的版本中移除
- #define nvmlClocksEventReasonNone 0x0000000000000000LL
-
位掩码，表示没有时钟节流
时钟尽可能高。

软件热降频
当前时钟已优化，以确保以下情况为真
-
当前 GPU 温度不超过 GPU 最大工作温度
-
当前显存温度不超过显存最大工作温度
-
- #define nvmlClocksEventReasonSyncBoost 0x0000000000000010LL
-
同步加速
为了最大限度地提高每瓦性能，此 GPU 已通过 nvidia-smi 或 DCGM 添加到同步加速组。同步加速组中的所有 GPU 将提升到整个组中可能的最低时钟频率。查看系统中其他 GPU 的节流原因，了解为什么这些 GPU 将此 GPU 保持在较低的时钟频率。

-
硬件降频（将核心时钟频率降低 2 倍或更多）已启用
这是以下情况的指示
-
温度过高
-
外部电源制动断言被触发（例如，由系统电源）
-
功耗过高，快速触发保护正在降低时钟频率
-
也可能在 PState 或时钟更改期间报告
-
此行为可能会在以后的版本中移除。
