Your RAM doesn't appear to be running at the correct speed. The RAM needs to be in the A2/B2 slots and DOCP needs to be enabled in the BIOS. Doing this should increase gaming/benchmark performance.
You don't have much space left on the SSD which could negatively impact performance.
As for the CPU & GPU monitor temps during the benchmark and report back the max they reach. If they are overheating they may thermal throttle to avoid damage. HWmonitor works well (disregard the clock speeds for the CPU as sometimes there off) or use HWmonitor for the GPU and AMD Ryzem Master for the CPU. https://www.cpuid.com/softwares/hwmonitor.html
