Tuning
Use these settings to control CPU operation mode. Available modes are:
| Control Mode | Description |
|---|---|
| Default | Changes the values of the system to Stock values, User cannot change any values in this mode. |
| Eco Mode | You can perform all supported operations except changing CPU frequency, Peak Core(s) Voltage, PPT, TDC, EDC limits, and changing control mode. |
| AMD Spec | Enables you to adjust PBO parameters (PPT, TDC, EDC)
up to but not exceeding the AMD spec limits.
|
| PBO | The Precision Boost Overdrive mode allows the
processor to run beyond the default infrastructure limits up to the
limits of the board to potentially achieve higher sustained frequencies.
|
| PBO Advanced | Sets a maximum boost frequency higher than the stock
frequency.
|
| Manual | You can change these additional settings
|
Curve Optimizer
Enables you to shift the Voltage/Frequency curve to include lower voltages (negative values). The larger the offset the larger the magnitude of the voltage shift.
Curve Optimizer is not enabled when:
- Tuning mode is Manual
- Legacy Compatibility Mode is selected
- Cores are parked
You can either leave this mode in the OFF position (default) or select the Mode as All Cores, Per Die, or Per Core.
Select Method as Automatic or Manual. Select the Offset Value only if the Method you selected in Manual.
Click the Optimize button. A pop-up appears informing you that: Running the curve optimizer is a long and invasive process. You will not be able to use any other tuning features until the process is complete. Your system may restart during this process, so it is recommended that you save any work and close all applications before proceeding.
You can optimize the following values:
- Max Offset Values: Set the required values within the allowed limits.
- Stress Test Duration: Set the required duration within these limits: 10 to 600 in step sizes of 1.
Click Optimize to begin optimizing.
You can view the percentage completion in the progress bar on the top-right side of the application. The estimated time to complete is displayed against ETA.
You cannot close the Ryzen Master application when curve optimizing is in progress. The information displayed under Gauges, Tuning, Curve Optimizer, Cores, CPU Voltage (VDDCR), and Additional Controls is read-only.
To stop optimizing, you can click the Stop button and click Stop on the confirmation message.
If you click Optimize again, a message indicating that the previous curve optimization was ended prematurely and some values had already been optimized appears. You have options to:
- Continue with Current Max Offset Value: Click Continue to begin from where the previous optimization was terminated, or click Restart to begin optimizing all over again.
- Restart with New Max Offset Value: Provide new Max Offset Value and Stress Test Duration value. Click Restart to begin optimizing again with the new values all over again.
Cores
Enables you to overclock individual cores with the required speed, select the active number of CCDs, disable individual cores, or display core performance order in both OC and OS modes.
| Parameter | Description |
|---|---|
| Active CCD Mode | Select the number of active CCDs. The available options depend on the program (SHP or STP) and the number of cores supported. |
| Combination | If multiple CCDs are active, you can select a combination of CCDs. The available combinations vary based on the program and core configuration. |
| Core Sync | With this option turned OFF, you can configure sync
options to set the core speed of individual cores.
With this option turned ON, you can disable sync options at the individual core level. |
| Disable Core | With the Core Sync OFF, you can click the disable icon at the right of each core to disable that individual core. Click the icon again to enable the core. |
CPU Voltage (VDDCR)
Only in the Manual Control Mode, you can configure the amount of voltage supplied to the processor’s cores. On select CPUs you may observe 2 voltages. Configure the CPU Voltage (VDDCR) values based your requirement.
Curve Shaper
Use the Curve Shaper to reshape the underlying CPU voltage/frequency curve across specific temperature and frequency bands. Unlike Curve Optimizer, which applies a uniform curve shift, Curve Shaper allows selective voltage adjustments where the CPU is stable or marginal. This enables finer-grain tuning for improved performance, efficiency, and stability across different workloads and operating conditions.
| Parameter | Description |
|---|---|
| Mode |
Enables or disables Curve Shaper control. Available options are:
|
| Temperature Bands | Curve Shaper divides operation into predefined temperature regions (for example: low, medium, and high temperature ranges). Each band can be tuned independently to account for thermal behavior changes. |
| Frequency Bands | Each temperature band is further split into multiple frequency ranges. This allows voltage to be adjusted precisely at specific operating points. |
| Adjustment Steps | Voltage adjustments are applied in Curve Optimizer–style steps. Positive values add voltage; negative values reduce voltage for the selected band. |
| Per-Band Voltage Control | Allows selectively removing voltage from stable frequency/temperature bands or adding voltage where instability is observed. |
| Scope of Application | The reshaped voltage curve applies to all CPU cores of a given core-type (for example: Standard or Dense) uniformly. |
| Interaction with Curve Optimizer | Curve Shaper defines the base curve shape; Curve Optimizer can then be used to shift the entire reshaped curve globally, per CCD, or per core. |
- Curve Shaper feature may not be available for all CPUs.
- Curve Shaper is not enabled when Control Mode is Manual.
Integrated Graphics
Integrated Graphics offers tuning and monitoring controls for the integrated AMD Radeon graphics engine built into AMD APU processors. Adjust GPU frequency, voltage, and curve optimizer offsets to optimize graphics performance.
- Enables you to shift the GFX Voltage / Frequency curve to include higher voltages (positive values) or lower voltages (negative values).
- The larger the offset entered the larger the magnitude of the voltage shift.
| Parameter | Description |
|---|---|
| Mode | Specify the mode:
|
| Current Frequency | Specify the required Current Frequency. |
| Curve Optimizer | Enable/Disable Curve Optimizer. |
| Max Voltage | Specify the required Maximum Voltage. |
| Curve Offset | Specify the Curve Offset value. |
Additional Controls
You can turn on or turn off the following additional.
| Parameter | Description |
|---|---|
| Simultaneous Multithreading | Enable/disable Simultaneous Multithreading. You cannot enable this mode if you have enabled Legacy Compatibility Mode. |
| Legacy Compatibility Mode | This feature is useful for improving performance for some games. When switched Off, all cores of the system are enabled; when switched On, half of the total cores will be active. This mode disables Simultaneous Multithreading, if it has been switched on. A message appears informing you that SMT is not available with this mode and all changes will be discarded if you switch to this mode. You must confirm to switch on this mode. |
| Max Temperature | The maximum safe operating temperature for the CPU. |
| I/O Clock Max | I/O Clock. Only specfic frequencies are permitted. Processor firmware will automatically round up to the nearest permitted frequency. |
