We overclock the Ryzen 7 9700F up to 5750 MHz in 5 minutes or less using the ASUS ROG Crosshair X870E Hero motherboard and AIO cooling.

I’ll speedrun you through the BIOS settings and provide 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 I. That will make the memory run at our EXPO-rated frequency of DDR5-8000 and timings. EXPO I will load only the primary timings and have the motherboard tune the secondary timings.

Set Memory Frequency to DDR5-7800. I had to do this to stabilize the system since DDR5-8000 didn’t work. You might not have to do this depending on the quality of your Ryzen 7 9700F.

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 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 sixteen cores are active is 1.35V, up 15 mV from the default limit of 1.335V.

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 1 MHz, though BIOSes usually provide 25 MHz steps.

Set Max CPU Boost Clock Override(+) to 200. This increases the Fmax of the eight Zen 5 CPU cores of this 9700F 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 it 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 value for your CPU rather than copy mine. I always try in steps of 5 magnitude.

Set All Core Curve Optimizer Magnitude to 30

Leave the Curve Optimizer submenu.

Then save and exit the BIOS.

Ryzen 7 9700F Overclock Performance Improvement

We re-run our 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 Core Clock reported in the operating system is 5750 MHz.

When running the OCCT CPU SSE Stability Test, the average CPU effective clock is 5355 MHz with 1.193 volts. The average CPU temperature is 95.2 degrees Celsius. The average CPU package power is 174.3 watts.

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