Hi Teacher,
When we ran the memory bandwidth stability test on Orin, the bandwidth kept jumping around a lot—like between 27.5GB/s and 33.5GB/s. Here are the test setup and commands we used. Could you mind taking a look at the config and see where we can tweak this test? Thanks!
The configuration is as follows：

  1. sudo nvpmodel -m 0 ; Max power
  2. jetson_clocks ；Frequence Max；
  3. Idle system；he system is running without any load；
    Test results:

Hi,
Please share which command you run to do the test. And do you use Jetpack 6.2?

Hi,
Please refer to the topic and run the mbw command. See if you get same result.
