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).

Apparently you can only enable 120 Mhz for PSRAM when you also meet some other criteria for the FLASH memory. For my ESP32-S3-F4R2 (which has both of them in the package) those criteria are not met, so it won't work. Maybe it's different in your situation.
