|
|
|
|
* **CPU:** Up to 1963MHz (Mariko) / 1785MHz (Erista)
|
|
* **GPU:** Up to 1075MHz (Mariko) / 921MHz (Erista)
|
|
* **RAM:** Up to 1866/2133MHz (Mariko) / 1600MHz (Erista)
|
|
* Over/undervolting support
|
|
* Built-in configurator
|
|
* Compatible with most homebrew
|
|
|
|
> It is recommended to read the [guide](https://rentry.co/howtoget60fps) before proceeding, as this can help you get a *significant* performance boost over the default settings, often times with less power draw and heat output
