Question RAM reverted randomly to 1333 Mhz

[Levkir]

So today i was checking my task manager cuz after the new windows update a few stuff was strange. Nevertheless i've found that my RAM speed has drastically slowed down: from 2666 Mzh to 1333 Mhz, basically halfed itself. I will check the BIOS later, long story short my TV cant display BIOS correctly and i cant do jack---- unless my friend brings over his monitor, so atm i cant revert it back (anybody has a fix for it? 😀 ). My question is what may have caused my RAM to revert itself, and how?

Rig:
Ryzen 7 1800x
MSI x370 gaming pro
2x8 GB G.Skill Ripjaws 3000Mhz
RX 580 8GB

Are you sure that the RAM speed has dropped? as 1333 @ DDR is equivalent to 2666?

Yeah you're right, the thing which confused me that it used to say im at 2666 in task manager now it only displays 1333 but in cmd i can see it's in 2666 😁 it is confusing why they changed it tho :/
