AMD Ryzen 3 2200G review - Overclocking The Ryzen 3 2200G processor

Overclocking

Overclocking and tweaking then. Always invest in good hardware by the way (MOBO/PSU/Memory/Cooling), the cheaper motherboards often are not well tuned for enthusiast overclocking. Also get yourself a good power supply and proper processor cooling. Overclocking with a more core processor (it doesn't matter if that is Intel or AMD) is far more difficult than you expect it to be.
  

For the Ryzen 3 2200G reference review we'll use nothing more than a stock cooler.

Overclocking multi-core on a high clock frequency is a relatively okay to do job, and can be best managed from the BIOS. You can also use AMD's software tool of course.

Our maximum was 3900 MHz on all four cores.

The Raven Ridge 4-core parts with one CCX are not the best overclockers (at least not our samples). During our measurements, by trial and error we found that at 1.40~1.45 Volts you will end up at roughly 3.9~4.0 GHz. You could apply a fixed voltage, but we do recommend a voltage offset (start with +200Mv) or, even better, leave voltage at auto and find your maximum multiplier.

BIOS Overclocking

The Guru3D reader-base overclocks mostly from the BIOS to try and find the maximum stable limit. The generic overclock procedure for multiplier based overclocking is as follows:

• Leave base clock (bus) for what it is right now (100 MHz)
• Set the per core multiplier at a maximum of your liking:
• Example 1: 100MHz x 39 = 3900 MHz
• Example 2: 125MHz x 31 = 3875 MHz
• Increase CPU voltage; though AUTO works fine on many motherboards you can do it manually as well. Start at 1.40 volts (or voltage offset (start with +200Mv)) and work your way upwards into a state of equilibrium in perf and cooling temps.
• Make sure your processor is properly cooled as adding voltage = more heat
• Save and Exit BIOS / uEFI
   

Here is an example of the Ryzen 3 2200G at 3900 MHz @ all cores. Here the stock cooler seems to run fine in the ~72 Degrees C range overclocked.

We have been able to sustain 3.9 GHz on all cores. Memory wise we had 3200 MHz CL14 stable (XMP enabled).

Results

Our default score was 340 seconds, the tweak now shaves off roughly 18 seconds of wPrime on a 1024M run. 

For CB15, tweaked we reach 596CB.

For Time Spy we are at 6199 at default, tweaked we reach 6267 points (obviously with a dedicated graphics card). The default CPU score was 3469, which tweaked is 3644. The lack of SMT hurts this score as well as the previous CB run.

Power Consumption

Adding extra voltage to the CPU for the OC also has an adverse effect on the overall energy consumption. Below, the power consumption for the whole PC measured at the wall socket side. Dark black is overclocked, the values are near similar for both the 2200G and 2400G once tweaked.
