I did read the fine documentation, but I'm afraid I didn't fully understand the consequences of enabling the experimental 120MHz support for SPIRAM.
We're using ESP32-S3-WROOM-1-N16R8 modules from our chinese supplier. They come with chip revision 0.2. What are the odds that these chips support 120MHz PSRAM in a stable way? And... if I enable 120MHz and it works -- can I assume it works reliably or will it perhaps be unstable later on in the process (with regards to increasing temperature).
