Overclocking Ryzen 3 3100/3300X on the X570/B450

OC of the Ryzen 3100 in watercooling on X570:

The test configuration:

• Motherboard: Asus Crosshair VIII Impact (bios 0050) (test)
• Processor: AMD Ryzen 3100
• Memory: 16 GB GALAX HOF OC LAB 4400 MHz C19 Water Cooling (test)
• Cooling: watercooling custom 360 mm EKWB
• Operating system: Windows 10 64 bits (version 1909)

First series of tests at stock frequencies:

The first step will be to test the performance of this Ryzen 3100 with default settings. In the bios, only the XMP profile of my memory kit has been activated with the FCLK frequency set to 1800 MHz.
At the operating system level, I have opted for the “AMD Ryzen Balanced” power profile as recommended by AMD.

For this first series of tests, I will use four benchmarks which are Cinebench R15, Cinebench R20, Geekbench 3 and Geekbench 5. In terms of software, you will need CPU-Z, Core Temp 1.15.1 and the overclocking software compatible with your motherboard. For our Asus Crosshair VIII Impact, this is TurboV Core.
Here are the results obtained with the processor temperature measured by Core Temp. The temperature of the liquid in my cooling loop was between 23 and 24 °C.

During the different benchmarks, I could observe that the frequency rises and reaches on the four cores a frequency of 3891 MHz. The Boost frequency announced by AMD is therefore well respected.

The overclocking of our Ryzen 3100:

As usual, I will start the tests by choosing, via the BIOS, a 4 GHz frequency applied on the 4 cores. The voltage to start my tests is set to 1.2 volt.
The idea is to test the stability on several runs under Cinebench R15. Then, I increase by steps of 100 MHz checking the stability. If it is not the case, I increase the voltage in 0.5 volt steps. I also changed the power profile in the OS to “High Performance”.

In order to modify the voltage and the multiplier coefficient on the fly, I use the Asus TurboV Core software. Depending on the brand of your motherboard, this software will be different.
Here are the results I obtained and the frequency needed to ensure stability on three consecutive runs.

This test method allows you to have “an idea” of the overclocking potential of your processor. For H24 overclocking, the maximum frequency should be lowered to ensure perfect stability. As I keep telling you, you don’t need Prime95 or OCCT for hours. The stability is specific to each user according to his use (games, benches, video software, …).

Cinebench R15 is the only benchmark I could run at 4600 MHz for a voltage of 1.35 volt. I had to lower the frequency to 4550 MHz for Cinebench R20 and Geekbench 3.4.2

My first impressions are rather good for this Ryzen 3100 which has a very excellent overclocking potential for a price displayed around a hundred euros. The continuation of the overclocking tests will be done with the 3300X.

The memory overclocking:

I wanted to make sure that I’ll be able to run my GALAX kit at 4800 MHz 14-13-13-28 with this Ryzen 3100. No problem to run the tests with this memory frequency. I just couldn’t switch the FCLK frequency to 1900 MHz like with my Ryzen 3600X. But this confirms all the good that I already think of this Ryzen 3 3100.
