5 Minute Overclock: AMD Ryzen 5 7600X to 5544 MHz
We’re overclocking the Ryzen 5 7600X CPU up to 5544 MHz in 5 minutes or less using the ASUS ROG Strix X670E-F Gaming Wifi 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 Ai 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 eCLK Mode to Asynchronous Mode. This enables an external clock generator to drive the CPU frequency. Ryzen 7000 has three clock generator modes: internal, external synchronous, and external asynchronous. In External Asynchronous mode, there are two external 100 MHz clock generators. One is used exclusively for the CPU core frequency and the other for the other parts inside the CPU.
BCLK2 Frequency to 109.25 MHz. That will increase our Precision Boost algorithm frequencies by 9.25%. In our case, the maximum boost frequency ceiling increases from 5450 MHz to 5954 MHz.
Set Memory Frequency to DDR5-5600. 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 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 is most impactful with multi-threaded processors. With the 6-core 7600X, we don’t even hit the platform limits at stock values. Ultimately, we don’t expect much performance improvement.
Set CPU Boost Clock Override to Enabled (Negative).
Set Max CPU Boost Clock Override to 375. This decreases the frequency ceiling by 375 MHz over the programmed max 1T limit. On this Ryzen 5 7600X, that’s 5450 MHz. Reducing this by 375 MHz results in a ceiling of 5075 MHz, but adjusted by our ECLK of 109.25 MHz, that becomes 5544 MHz.
Enter the Curve Optimizer submenu and set Curve Optimizer to All Cores
Here’s where the real magic happens as curve optimizer allows us to adjust the VFT 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. That is what we need in our overclock.
The Precision Boost algorithm is ECLK-unaware, meaning if Precision Boost boosts to 5000 MHz at 1.1V, with a 109.25MHz ECLK, it boosts to 5463 MHz at 1.1V. That won’t be stable. With a positive curve optimizer, we can increase the voltage at a given frequency, thus ensuring stability when using reference clock overclocking.
- Set All Core Curve Optimizer Sign to +
- Set All Core Curve Optimizer Magnitude to 30. This will give us the maximum additional voltage using Curve Optimizer.
- Leave the Curve Optimizer submenu
- Leave the Precision Boost Overdrive submenu
- Set CPU Core Voltage to Offset mode.
- Set offset Mode sign to +
Set CPU Core Voltage Offset to 0.05. This will add an additional 50mV on top of the voltage requested by the Precision Boost algorithm.
Then save and exit the BIOS.
Ryzen 5 7600X 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 +8.80% in the AI Benchmark.
The highest Core Clock reported in the operating system is 5544 MHz for every CPU core.
When running Prime 95 Small FFTs with AVX disabled, the average CPU effective clock is 5119 MHz with 1.387 volts. The average CPU temperature is 94.9 degrees Celsius. The ambient and water temperature is 26.9 and 34.1 degrees Celsius. The average CPU package power is 130.4 watts.
And that’s it, thanks for watching and see you next time!
