RAM Frequency Issues

This is normal. DDR4 has a double data rate, so DDR4-3000 runs at 1500MHz = 3000 MT/s.

I was in task manager trying to get some performance charts when running a program and noticed my RAM's frequency was only 1500MHz. I went into bios and it's set to 3000MHz. I thought Task Manager was just reporting the wrong info but even CPU-Z has the same frequency showing. 

 

CPU: Ryzen 3 2200g (Non-OC) (GPU part manually disabled in BIOS)

RAM: Corsair Vengeance 16gb 2x8gb (stock 3000MHz)

M/B : Asus Prime B450-PLUS

So if I were to OC the RAM speed to 3200MHz then Windows would report 1600MHz which would be 3200MT/s

Windows is weird I have had some builds report the effective speed 3000Mhz and some builds give the clock rate 1500Mhz.
