I m having issue with ram speed. I m using Corsair vengeance DDR4 3000mhz ram. Task manager and cpu-z shows the speed as 1500mhz but the bios is showing the speed as 3000mhz. I m using a MSI b450 Pro vdh plus motherboard. I don't know which one is right. This problem arose after updating to windows 10 version 1909 and before updating the speed was 3000mhz. Can someone help me to understand the problem?
