- There is **no dynamic frequency scaling** in HOS, which makes _overclocking acts differently than PC_ or other mobile devices. The console will be _sticking to what frequency you've set in the long term_, until you close the game or put it into sleep.

- **ONLY ramp up RAM clock** beyond HOS maximum to 1862 / 1996 MHz if you want to _stay safe_. Higher RAM clock could be UNSTABLE and cause graphical glitches / instabilities / filesystem corruption.

## Why no CPU/GPU OC for Erista?
|
||||
|
||||
- Tegra X1 on Erista is on TSMC 20nm HPM node, consumes much more power (~2x) and generates much more heat, compared to Tegra X1+ on Mariko (TSMC 16nm FinFET).
|
||||
- Erista Switch uses lower speedo (=== lower quality === higher voltage required) SoC from NVIDIA. You will NOT get comparable performance to NVIDIA Shield TV no matter what.
|
||||
- Snapdragon 810 (4 x A57 @ 2.0GHz + 4 x A53) also uses 20nm HPM, see how it plagued Android phones in 2014.
|
||||
|
||||
- The board power supply is quite limited, even if you've done cooling mod.
|
||||
- You could spot battery draining at higher clocks under stress test, even with official 39W PD charger.
|
||||
- CPU / GPU performance at max clocks will be worse if power supply is not enough.
|
||||
- Higher RAM clocks (> 1996.8 MHz) could be UNSTABLE and cause graphical glitches / instabilities / filesystem corruption. **Always make backup before usage.**

- Erista: Minerva module conflicts with HOS DRAM training. Recompile with frequency changed is recommeded, although you could simply remove `bootloader/sys/libsys_minerva.bso`.
