We’re overclocking the Ryzen 7 9700X up to 5750 MHz in 5 minutes or less using the ASUS ROG Crosshair X670E Hero motherboard and AIO 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 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 guide.

All right, let’s do this.

5 Minute Speedrun

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

Set Ai Overclock Tuner to EXPO II. That makes the memory run at our EXPO-rated frequency of DDR5-6400 and associated primary memory timings and voltage.

Switch to the Advanced menu.

Enter the AMD Overclocking submenu. This will provide us with all the advanced AMD CPU overclocking tools.

Click Accept

Enter the Precision Boost Overdrive submenu. Here, we can use the AMD Precision Boost Overdrive 2 toolkit 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:

Set Precision Boost Overdrive Scalar Ctrl to Manual. That enables us to increase the override the warranted silicon stress level, or FIT, which is one of the Precision Boost limiters governing the maximum allowed operating voltage.

Set Precision Boost Overdrive Scalar to 10X. This increases the FIT to ten times the factory-fused value. Now, the maximum voltage when all eight cores are active is 1.375V, up 25 mV from the default limit of 1.35V.

Set CPU Boost Clock Override to Enabled (Positive). That unlocks the ability to increase the CPU’s programmed Fmax, or maximum frequency, up to 200 MHz in steps of 25 MHz.

Set Max CPU Boost Clock Override(+) to 200. This increases the Fmax of the eight Ryzen 7 9700X Zen 5 CPU cores from 5550 MHz to 5750 MHz.

Enter the Curve Optimizer submenu. Here’s where the real magic happens as curve optimizer allows us to finetune the V/f curve for each core in a positive or negative direction. Each step represents around 5mV. On Ryzen 9000 processors we can set the Curve Optimizer for all cores, per CCD, or per core.

Set Curve Optimizer to All Cores.

Set All Core Curve Optimizer Sign to Negative. Setting a negative offset means the CPU will use less voltage for a given frequency and boost to a higher frequency at a specific voltage. Setting a positive offset means the CPU will use more voltage for a given frequency and boost to a lower frequency at a particular voltage. It’s the former we need in our overclock. Note that the Curve Optimizer settings are highly CPU-specific, so you should find the best values for your CPU rather than copy those of my Ryzen 7 9700X.

Set All Core Curve Optimizer Magnitude to 35.

Leave the Curve Optimizer submenu.

Leave the Precision Boost Overdrive submenu

Then save and exit the BIOS.

Ryzen 7 9700X 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 Geomean performance improvement is +7.91%, and we get a maximum improvement of +21.77% in AI Benchmark.

The highest Core Clock reported in the operating system is 5750 MHz.

When running the OCCT CPU SSE Stability Test, the average CPU core effective clock is 5508 MHz with 1.229 volts. The average CPU temperature is 95.1 degrees Celsius. The average CPU package power is 164.0 watts.

And that’s it. I thank you for watching and the Patreons for the support. See you next time!
