Review Should you get dual channel RAM for Ryzen APU gaming? (Ryzen 3500U) - AFG's Collab Review

Introduction:
We were curious to see how the artificial power limitations on Ryzen Mobile imposed by OEMs would affect performance of the Ryzen 5 3500U. Ryzen Controller, also known as RyzenAdj, developed by "Storm1er" allows the user to bypass some of these power and thermal limits set by OEMs. We tested our laptop's baseline fps, then used Ryzen Controller. We also tested the effect of upgrading from our baseline 8GB DDR4-2400 memory to 16GB DDR4-2400 memory (dual channel 2 x 8GB). Our final test combines the two modifications together for our highest result.

Methodology:
The laptop being tested is the Lenovo Thinkpad e495. Windows 10 Home 1903 64bit was used alongside the "high performance" power plan. The only game tested is Sleeping Dogs Definitive Edition, as it was the easiest "real world" game to benchmark in our Steam library. The game was tested on the medium pretest at 1080p resolution with VSync off.



Recommendations:
If you plan on gaming on the mobile Ryzen APU platform, we strongly suggest picking up a 8GB DDR4-2400 stick of SO-DIMM for your notebook. There is a massive uplift in fps without changing the power settings of the laptop. This is the safest and most notable improvement to fps. We estimate a negligible impact to power consumption (and thus battery life) and negligible increases to heat output. This cannot be said for Ryzen Controller, although we did not have the equipment to test the increases to heat/power draw.
