    Ryzen 5 2400g throttles to about 20% GPU / 80% CPU of max performance. Needs restart to be fixed.

      Hi,

       

      I have a problem with throttling of the APU. For the last 1-2 days, it started to throttle to 20% of the GPU and about 75% of the CPU max performance after a brief gaming or other heavy loads.

       

      The problem can be fixed by restarting the system, but it comes up after another brief gaming (5 min) or heavy load.

       

      I found a similar problem described in the following Tom's Hardware review - AMD Raven Ridge Thermal/Power Analysis: Ryzen CPUs With Vega

       

      Examples of the performance hit:

       

      1.World of Warships with High settings - normally 50-70 FPS, when bugged -> 10-15 FPS

      2. Heaven Benchmark Extreme - normally  10-15 FPS, when bugged -> 2-3 FPS

      3. GTA 5 with High settings - normally 40-50 FPS, when bugged -> 10 FPS

      4. Geekbench 4 CPU test: normally ~4250/12500 score, when bugged ~3000/10000

       

      My system is the following:

       

      CPU: Ryzen 5 2400g with the stock fan and no overclocking

      Motherboard: ASUS TUF B350M-Plus Gaming with latest 3805 BIOS

      RAM: 2x4GB Kingston Hyper 3000Mhz

      SSD: Crucial MX500 500GB

       

      P.S. - Previously, also had frame drops for 2-3 secs periodically. Now it just unplayable.

       

      SOLUTION: WINDOWS reinstall resolved the throttling.

       

      Occasional frame drops fixed by disabling CPU Turbo boost.
