Running my Ryzen 5 1600 beyond its default performance causes issues with memory speed.
I’m noticing an unusual issue with my CPU overclock. When I go above the stock speed of my Ryzen 5 1600, my memory performance drops significantly. CPU-Z shows the RAM running at 3200 MHz, but SiSoftware Sandra reports a much lower frequency—about 2.69 MHz when the CPU is at 3.8GHz. Even pushing the CPU to 3.9GHz widens the discrepancy between the two tools. This inconsistency affects overall system performance. I’ve also verified RAM speed using AIDA64’s benchmarks; it shows the best bandwidth with the stock configuration, which aligns with the lower frequency reported by SiSoftware Sandra when overclocked. Could there be something I’m overlooking?
I configured all my settings in the BIOS. The 3.8GHz overclock was done by increasing the CPU multiplier to 38 and the CPU voltage to 1.25V. My memory frequency is also set to 3200MHz, with nothing left on Auto.
The VDDCR Soc voltage wasn't the issue; I tried different voltages from 1V to 1.2V and also raised the CPU voltage to 1.3V. It appears I'm encountering a 2666MHz memory bandwidth limit that only appears when exceeding the CPU frequency specifications.
Amd said that the maximum ddr4 for ryzen 5 1600 is 2400 and no guarantee that higher speed will work so I think u should try to overclock u ram at 2400 and check u performance I got an ryzen 1600 with 16 GB ddr4 at 2400 an the performance are great hope this helps peace.
