We overclock the Intel Graphics for Arrow Lake up to 3100 MHz in 5 minutes or less using the ASUS ROG Maximus Z890 Apex motherboard and custom loop water cooling.

I’ll speedrun you through the BIOS settings and provide some notes and tips along the way. Please note that this is for entertainment purposes only and not the whole picture. Please don’t copy these settings and apply them to your system. If you want to learn how to overclock this system, please check out the longer SkatterBencher guide.

All right, let’s do this.

5 Minute Speedrun

When you’ve entered the BIOS, go to the Extreme Tweaker menu.

Set Performance Preferences to ASUS Advanced OC Profile. This sets a number of BIOS options that help with overclocking, including some that override Intel’s default parameters.

Set Ai Overclock Tuner to XMP I. This lets us rely on the Intel Extreme Memory Profile 3.0 technology and will make our memory run at its rated speed of DDR5-8000. Selecting “XMP I” means the motherboard will load the XMP profile’s primary timings, frequency, and voltage. However, we let the motherboard tune the secondary timings.

Set ASUS MultiCore Enhancement to Enabled – Remove All Limits. This unleashes the Turbo Boost 2.0 power limits and lets the CPU run at unlimited power indefinitely.

Set Max. CPU Graphics Ratio to 62. That increases the GPU frequency to 3100 MHz because the 100 MHz reference clock is first divided by 2, then multiplied by the Graphics Ratio.

Set NGU Ratio to 34. That increases the NGU frequency by 800 MHz from the default 2.6 GHz.

Set CPU Graphics Voltage to Manual Mode. That switches the VccGT voltage rail configuration mode from the standard dynamic SVID to static PMBus, which helps us avoid some of the performance throttling problems SVID mode introduces.

Set CPU Graphics Voltage Override to 1.300.

Set CPU System Agent Voltage to Manual Mode. This dynamic voltage rail powers several parts of the SOC dielet, including the NGU, IMC, and NPU. By setting it to manual mode, we can set a static output voltage from the voltage regulator.

Set CPU System Agent Voltage Override to 1.300.

Then save and exit the BIOS.

Intel Graphics (Arrow Lake) Overclock Performance Improvement

We re-run some benchmarks to ensure everything works as intended and check the performance increase compared to the default settings. Higher is better, and all are higher.

The highest Graphics Clock reported in the operating system is 3100 MHz.

When running the 3DMark Speedway Stability Test, the average GPU clock is 3100 MHz with 1.249 volts. The GPU memory clock is 4000 MHz. The average GPU Temperature is 39 degrees Celsius, and the average GPU Cores Power is 18.8 watts.

And that’s it. Thank you for watching and the patrons for their support, and see you next time!
