Task Manager in Windows 10 displays wrong memory speed...

Hello! I have a Lenovo Y700 gaming laptop with 8GB of DDR3 RAM. (AMD-FX Edition). I had to create a new user account due to issues I had with my other one. Everything was okay until I looked at Task Manager and realized it displays my memory speed as 800 MHz instead of its actual speed of 1600 MHz! This started to occur ONLY when I made the new account! I was wondering if this is a bug in Windows 10, or if something managed to happen with my memory when I made the new account for whatever...
