- **Auto-Boost CPU for faster game loading**
 - **Fan Control Optimization** at high load
 - **Modded sys-clk and ReverseNX**(-Tools and -RT)

 #### Details

 - **Overclock**
+
  - **Official X1+ CPU/GPU OC clock: 1963.5/1267.2 MHz**.
-    - Anything above that are not in the table of official module and are all wild guess.
-    - Coefficients are not correctly calculated, so max clock(2397.0/1344.0 MHz) may not work on some devices. ([#4](https://github.com/KazushiMe/Switch-OC-Suite/issues/4))
-  - **Recommended RAM clock: 1862.4 MHz** @ 600mV, (**1795.2 MHz for Hynix** ones).
-    - **RAM clock is set permanently** via **ptm-patch**, rather than sys-clk.

+    - **RAM clock is set permanently** via patching ptm module, rather than sys-clk.
    - Use Hekate to check out the brand of your RAM chips.
    - EM shielding & thermal paste for RAM chips and testing with emuNAND before long-term usage.
+
+  - Mariko variants have much lower power consumption compared to Erista, therefore **GPU clock capping is lifted for Mariko**.
+
+  - For more info, see [README.md](https://github.com/KazushiMe/Switch-OC-Suite/tree/master/Source/sys-clk-OC) in sys-clk-OC.
+
+- **Overvolt and Extreme Overclock**
+
+  - CPU overvolting: 1220 mV, up from default 1120 mV. Frequencies ≥ 2193 MHz will enable overvolting.
+
+  - GPU overvolting: implemented but disabled, default 1050 mV. ([issue #4](https://github.com/KazushiMe/Switch-OC-Suite/issues/4))
+  > Although Tegra X1+ GPU has much more potential than X1, and overvolting is quite promising, its power draw is not tested at higher voltage and its performance is hinderded by low RAM bandwidth on most occasions.

  - RAM overvolting: precompiled hekate bootloader is provided

+    - Edit `oc.ini` to change Vddq voltage value:
      ```ini

      ```
-    - Overvolting beyond 650mV is not recommend and it might fry your DRAM.
-    - > Even though Tegra X1+ supports LPDDR4/LPDDR4X, LPDDR4X DRAM chips are not required to be backward-compatible with, or resistant to LPDDR4 1.1V Vddq voltage.

- **Auto-Boost CPU for faster game loading**
-    - When a game launches or is in loading screen, sys-clk will boost CPU to 1963.5 MHz for ~10 seconds or until the loading screen ends.
-    - Some games don't utilize `SetCpuBoostMode` at all, e.g. Overcooked 2, so Auto-Boost will be unavailable to these games.
-    - To **disable this feature**, simply remove `boost_start.flag` and `boost.flag` in `/config/sys-clk/ `.
+
 - **Fan Control Optimization** at high load
  - Higher tolerable temperature and smoother fan curve. Set `holdable_tskin` to 56˚C. Previously it's set to 48˚C, so by default the fan would go crazy (80~100%) easily with a slight degree of OC.
  - Replace crappy factory thermal paste is preferred.
  - Place a thermal pad onto Wi-Fi/BT module (shielded, adjacent to antennas) to lower tskin temperature.

 - Option to change the threshold for chargers providing enough power
    - Find the string `enough_power_threshold_mw` in `system_settings.ini`. The default value is `0x9858` (39,000 mW).
