OC Switchcraft EOS 1.7.1

• Requires Atmosphere 1.10.1

• Improved the CPU "Auto" algorithm and slightly adjusted CPU tables

• Added the open-source Helios CPU table

• Extended „High Freq Vmin“ range

• 2703 MHz "Max CPU Frequency" and "Boost Clock" added to the Toolkit
  (not recommended)

• Minor UI bug fixes

• sys-clk-eos 1.3.0

- Implemented GPU load driver for accurate GPU utilization 
- Overlay now shows CPU/GPU/RAM load 

Notice:
Use it only with a NAND backup.
Unstable settings can lead to NAND corruption.

Update:

• GPU Scheduling fix
• Low Freq Vmin fix

Update 2:

• Loader: added accurate ‘valid-nso-set’ checks

OC Switchcraft EOS 1.6.9

• Requires Atmosphere 1.9.5

• Ultrahand 2.1.3

• CPU undervolting bug fixes

• Renamed “DVFS” to “Auto Vmin”

• sys-clk-eos 1.2.7

- Mitigated issue where GPU is stuck at 76 MHz on game crash or homebrew exit
- Boost mode override has been renamed for less ambiguity
- More reliable boost clock detection 
- Reworked Auto CPU boost 
- Auto GPU Vmin fix
- Reworked handheld capping
- Renamed config commands

Notice:
Use it only with a NAND backup.
Unstable settings can lead to NAND corruption.

OC Switchcraft EOS 1.6.8

• Atmosphere 1.9.4 required
• Compatibility update

Notice:
Use it only with a NAND backup.
Unstable settings can lead to NAND corruption.

OC Switchcraft EOS 1.6.7

• Atmosphere 1.9.3 required
• Ultrahand 2.0.1

sys-clk-eos 1.2.4:
- Reworked clock cappings
- Handheld capping lower bound is set to 460
- Minor fix for reversenx sync

loader & Toolkit:
- Improved CPU UV table shift fix
  Allows a lower „High Freq Vmin“ on some switches 
- GPU UV3 removed
- The Custom Table can now be applied to all UV tables
  Allows fine-tuning of UV tables or replacing all voltages, similar to UV3

Attention:
If you used GPU UV1 or UV2, restoring the “Default Table” in “Custom Table” is required.
No changes are needed if you were using GPU UV3.

Notice:
Use it only with a NAND backup.
Unstable settings can lead to NAND corruption.

Update 1.6.7:

• CPU UV bugfixes
• Minor UI improvements and bug fixes in the Toolkit

OC Switchcraft EOS 1.6.5.1

• Atmosphere 1.9.3 required

• Ultrahand 2.0.0

• nx-ovlloader+ v1.1.1

• sys-clk-eos 1.2.2:

• GPU DVFS voltages for high speedo bracket is fixed, fine tuned for other speedos

• Offset value is used instead of override for multiple ram frequencies / multiple boot entries support

• Auto CPU boost threshold increased from 90% to 95%.
  This feature is not intended as a governor but rather pseudo boost mode, hence it was raised.
  (At 90% it will make clock fluctuate for some games or hbmenu)

• Minor bug fixes

DVFS Methods
Using the official service method is recommended, as hijacking the official sysmodule can lead to instability.
If another process accesses the sysmodule while it is being hijacked, it may result in system crashes or hangs.

However, if you require a voltage offset for fine-tuning, the hijack method can be used to set precise voltages.
Use this method with caution.

Update 1.6.5.1:

• Increased offset voltage range.

Notice:
Use it only with a NAND backup.
Unstable settings can lead to NAND corruption.

OC Switchcraft EOS 1.6.4

• Atmosphere 1.9.2 required
• Added support for HOS 20.2.0
• Toolkit UI improvements
• sys-clk-eos 1.2.0 + 2.0.1+r9
• Ultrahand 1.10.0

Notice:
Use it only with a NAND backup.
Unstable settings can lead to NAND corruption.

OC Switchcraft EOS 1.6.3.1

• Atmosphere 1.9.1 required
• UI tweaks and minor visual fixes
• sys-clk-eos 1.2.0 + 2.0.1+r7
• Ultrahand 1.9.6

Notice:
Use it only with a NAND backup.
Unstable settings can lead to NAND corruption.

OC Switchcraft EOS 1.6.3

• Atmosphere 1.9.1 required

• Added USB 3.0 enable patches

• Fixed bugs related to GPU DVFS Vmin and backup system

• GPU DVFS mode selection is now available in the Toolkit.
  (Setting a manual “Vmin RAM OC” value or applying a voltage offset enables the hijack method)

• default GPU vmin changed to 550 mV

• Ultrahand 1.9.5

Notice:
Use it only with a NAND backup.
Unstable settings can lead to NAND corruption.
