I'm using an Adata XPG 3000Mhz ram and the clock speed shown in the BIOS was 2666Mhz and windows task manager is showing only 1333Mhz.
I tried CPUZ and it also showed the same speed from the task manager. I only a single stick of 8GB ram. Everything was perfect before when I assembled the PC. Recently I updated my Window and this happened.
Can anyone give a fix?

Update: I tried Linux and it showed the correct speed which was 2666Mhz. I then formatted my windows drive and reinstalled windows and now in task manager, there is no such thing as memory speed. WTF Microsoft!

Open CMD with administrator privileges and type the following command.

wmic MemoryChip get BankLabel, Capacity, MemoryType, TypeDetail, Speed

Now this will return the actual RAM clock speed
