5 Minute Overclock: AMD Radeon Graphics (Ryzen 7000) to 3100 MHz
We’re overclocking the AMD Radeon Graphics integrated in the Ryzen 7000 CPUs up to 3100 MHz in 5 minutes or less using the GIGABYTE B650E Aorus Tachyon motherboard.
I’ll speed run you through the OC 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 outright 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 article.
Alright, let’s do this.
5 Minute Speedrun
Click the XMP/EXPO Disabled button. That will make the memory run at our EXPO-rated frequency of DDR5-6400 and timings.
Switch to Advanced Mode
Set GFX Clock Frequency to 3100MHz. This will effectively overclock the integrated graphics to run at 3.1 GHz with the maximum default voltage of 1.25V. However, we can only run up to 2975 MHz stably at that voltage so we’ll increase the voltage with other settings.
Enter the Advanced CPU Settings submenu
Enter the Precision Boost Overdrive submenu. Here is where we will do most of the performance tuning as PBO provides us with tools to increase the power, current, and frequency headroom of the Precision Boost 2 boost algorithm.
Set Precision Boost Overdrive to Advanced
Set PBO Limits to Motherboard. This adjusts the PBO platform parameters PPT, TDC, and EDC according to the motherboard auto-rules. On this motherboard, we find that the following values have changed:
- PPT limit from 230W to 720W
- TDC limit from 160A to 480A
- EDC limit from 225A to 640A
Enter the GFX Curve Optimizer submenu
Set GFX Curve Optimizer to GFX Curve Optimizer. Here’s where the real magic happens as GFX Curve Optimizer allows us to adjust the V/f curve of the integrated graphics by up to 30 steps in a positive or negative direction direction. Each step represents around 5mV.
Setting a negative curve means the graphics will use less voltage for a given frequency. Setting a positive curve means the CPU will use more voltage for a given frequency. It’s the latter we need to further increase the graphics voltage from 1.25V to 1.40V.
Set GFX Curve Optimizer Sign to Positive
Set GFX Curve Optimizer Magnitude to 30. This increases the maximum voltage from the default 1.25V by 30 steps of 5mV to 1.40V.
Radeon Graphics (Ryzen 7000) Overclock Performance Improvement
To ensure everything is working as intended, we re-run some benchmarks and check the performance increase compared to the default settings. With a graphics frequency running now 40% higher than stock, we get a significant performance improvement in most benchmark applications. We see a maximum performance improvement of +41.67% in Tomb Raider.
When running Furmark GPU Stress Test, the average GPU effective clock is 3100 MHz with 1.395 volts, and the GPU Memory clock is 3200 MHz. The average GPU temperature is 52.8 degrees Celsius. The average GPU+SOC power is 60.689 watts.
And that’s it, thanks for reading and see you next time!
