How to Use More Clock Tool for AMD GPUs
⚙️ What is More Clock Tool 1?
- More Clock Tool 1 (MCT1) is a utility for fine-tuning AMD GPU clocks (core and memory) beyond what stock drivers allow.
- It helps increase performance, but overclocking carries risks like instability, crashes, or hardware stress.
- Always proceed gradually and monitor your GPU carefully.

🛠Preparations
Backup Settings
Record your current GPU clock, voltage, and fan settings. You’ll want to revert if something goes wrong.
Monitoring Tools
Use software like GPU-Z to track real-time clocks, voltages, and temperatures. Other hardware monitoring tools can help.
Stable Drivers
Ensure your AMD drivers are up to date and stable. Conflicting tools may interfere with tuning.
Small Steps
Make incremental changes to clocks or voltage, testing stability after each step.

🚀 How to Use More Clock Tool 1
Launch the Tool
Open MCT1. You’ll see fields for core clock, memory clock, and possibly voltage offsets.
Select GPU / Profile
If multiple GPUs are installed, choose the one you want to tune.
Enable Tuning / Advanced Mode
Most tools require enabling tuning or accepting a warning.
Adjust Core Clock
- Start with a small increase (e.g., +25 MHz).
- Apply the change and test for stability with a benchmark or game.
Adjust Memory Clock
- Increase memory clock gradually (e.g., +50 MHz).
- Watch for crashes or visual artifacts.
Voltage Offset (Optional)
- Increase or decrease slightly if your GPU supports it.
- Avoid large changes—too much voltage can damage hardware.
Test Stability
- Stress-test your GPU with tools like FurMark, 3DMark, or in-game sessions.
- If unstable, revert to previous stable settings.
Save Profile
- Lock the settings or save a profile in the tool if supported.
- Reboot and retest for persistence.
Iterate
- Increase clocks further only if previous changes were stable.

🧩 GPU Series-Specific Tips
AMD 5000 Series (RX 5000 / RDNA 1)
Smaller voltage and clock headroom — proceed gently.
Recommended starting steps:
- Core: +10–30 MHz
- Memory: +50–100 MHz

Recommended starting steps:
- Core: +10–30 MHz
- Memory: +50–100 MHz
AMD 6000 Series (RX 6600, 6700, 6800, 6900 / RDNA 2)
Often requires increasing power limit to maximize clocks.
Recommended starting steps:
- Core: +20–50 MHz
- Memory: +100–200 MHz
Consider raising the minimum clock floor to reduce fluctuations.
Watch for cold-boot instability or artifacts.

AMD 7000 Series (RX 7800, 7900 / RDNA 3)
Efficiency is high; small voltage increases often suffice.
Recommended starting steps:
- Core: +10–40 MHz
- Memory: +100–200 MHz
Use AMD driver tuning features alongside MCT1 for best results.
Always monitor temps and power, as headroom may be narrower.

⚠️ Tips & Warnings
- Each GPU is unique — results vary due to silicon lottery.
- Never exceed safe voltage or temperature limits.
- Keep a known-good default profile to revert to.
- If instability occurs, boot into safe mode or revert settings.
- Overclocking can void warranty — proceed at your own risk.
