We’re overclocking the Ryzen 7 5800X3D CPU up to 4741 MHz in 5 minutes or less using the ASUS ROG Crosshair VIII 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, go to the Extreme Tweaker menu

Set Ai Overclock Tuner to D.O.C.P. Standard. That will make the memory run at our XMP-rated frequency of DDR4-4266 and timings.

Set BCLK Frequency to 104.20. That will increase our Precision Boost algorithm frequencies by about 4.2%. In our case, the maximum boost frequency ceiling goes up from 4550 MHz to 4741 MHz.

Set Memory Frequency to DDR-3681MHz. Because we increased the BCLK frequency by 4.2%, our XMP-rated frequency also increased 4.2% to DDR4-4445. Since this is too high, we set a lower memory frequency.

Set FCLK Frequency to 1840MHz. That ensures we run the memory, memory controller, and infinity fabric in synchronous mode.

Set Core Performance Boost to Enabled. That will ensure Precision Boost Overdrive is enabled while using a manual BCLK frequency

Enter the External Digi+ Power Control submenu

Set Core Voltage Suspension to Enabled. Voltage Suspension will force the CPU core voltage to stay within a specific range even when relying on the dynamic voltage of Precision Boost 2.

Set Co mitigator to 0.3. That helps mitigate system instability when using aggressive curve optimizer settings by continuously boosting the voltage under very light loads.

Set Voltage Floor Mode to Dynamic. Dynamic mode allows us to configure a custom voltage temperature curve. That will make the target voltage range change based on the operating temperature. The Voltage floor is the lower bound for the target voltage

Set Voltage Ceiling Mode to Dynamic. The voltage ceiling is the upper bound for the target voltage

Voltage suspension is effective up to 0.3V delta between requested and target voltage. If the CPU requests 1.4V, then the effective voltage will be 1.375V as the difference between both values is less than 0.3V.

Leave the External Digi+ Power Control submenu

Enter the Tweaker’s Paradise submenu

Set Force OC Mode Disable to Enabled. That will ensure manual OC Mode is disabled while using a manual BCLK frequency.

Leave the Tweaker’s Paradise submenu

• Set CPU Core Voltage to Offset mode
• Set offset Mode sign to +
• Set CPU Core Voltage Offset to 0.05

Go to the Advanced menu

Enter the AMD CBS submenu

Enter the CPU Common Options submenu

Set Global C-State Control to Enabled. That will ensure proper frequency scaling when the BCLK frequency is over 101 MHz.

Then save and exit the BIOS.

Ryzen 7 5800X3D 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 +13% in the AI Benchmark.

When running Prime 95 Small FFTs with AVX enabled, the average CPU effective clock is 4214 MHz with 1.176 volts. The average CPU temperature is 93.4 degrees Celsius. The ambient and water temperature is 24.4 and 32.2 degrees Celsius. The average CPU package power is 125.6 watts.

When running Prime 95 Small FFTs with AVX disabled, the average CPU effective clock is 4359 MHz with 1.208 volts. The average CPU temperature is 86.7 degrees Celsius. The ambient and water temperature is 24.4 and 31.6 degrees Celsius. The average CPU package power is 131.7 watts.

And that’s it, thanks for reading and ’till the next time!
