5 Minute Overclock: AMD Ryzen 7 7700X to 5747 MHz

ryzen 7 7700x 5 minute overclock

We’re overclocking the Ryzen 7 7700X CPU up to 5747 MHz in 5 minutes or less using the ASUS ROG Crosshair X670E Extreme motherboard and EK-Quantum custom loop water cooling.

I’ll speed-run 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 article.

Alright, let’s do this.

5 Minute Speedrun

When you’ve entered the BIOS, switch to the Advanced Mode view.

Then enter the Extreme Tweaker menu.

Set Ai Overclock Tuner to EXPO II. That will make the memory run at our EXPO-rated frequency of DDR5-6400 and timings. EXPO I will load only the primary timings and have the motherboard tune the secondary timings. EXPO II will load the entire profile without motherboard adjustments.

Set Memory Frequency to DDR5-6000. While our memory kit is rated at DDR5-6400, unfortunately, our CPU isn’t able to run that frequency. By enabling EXPO, we still benefit from the improved memory timings.

Enter the DRAM Timing Control submenu

Set Memory Context Restore to Disabled. This forces the CPU to retrain the memory at every boot. The benefit is that it helps improve stability at higher memory frequencies; the downside is that the boot process will take longer to complete.

Leave the DRAM Timing Control 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 Enabled. 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:

Increasing the platform boost parameters typically have the most significant effect on multi-threaded processors. For Ryzen 7000, however, AMD’s default platform parameters are relatively unconstraining. With the 8-core 7800X, we don’t hit the platform limits at stock values. So, ultimately, we don’t expect much performance improvement.

Set CPU Boost Clock Override to Enabled (Positive).

Set Max CPU Boost Clock Override to 200. This increases the frequency ceiling by 200 MHz over the programmed max 1T limit. On this Ryzen 7 7700X, that’s 5550 MHz. Increasing this by 200 MHz results in a ceiling of 5750 MHz.

Enter the Curve Optimizer submenu and set Curve Optimizer to Per Core

Here’s where the real magic happens as curve optimizer allows us to adjust the V/f curve for each core by up to 30 steps in a positive direction and up to 300 steps in a negative direction. Each step represents around 5mV.

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 is the former that we need in our overclock.

  • For every core, set Curve Optimizer Sign to Negative
  • For Cores 0, set Curve Optimizer Magnitude to 20
  • For Core 1, set Curve Optimizer Magnitude to 18
  • For Cores 2, 3, 4, and 5, set Curve Optimizer Magnitude to 22
  • For Core 6, set Curve Optimizer Magnitude to 14
  • For Core 7, set Curve Optimizer Magnitude to 16

Then save and exit the BIOS.

Ryzen 7 7700X 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. Higher is better, and all are higher. We see a maximum performance increase of +8.02% in the AI Benchmark.
