Memory not as fast as advertised?

This is most likely a stupid question, but I was talking to a friend about upgrading his PC and at some point RAM came up. I couldn't remember what speed I had so I looked up how to do find it and found out I can look at it more easily through the command "wmic memorychip get speed" which displayed two lines of "2666". That to me seems like I have two sticks of 2700 Mhz but I looked at the online receipt I got a while back and it clearly says "CORSAIR 16GB 2X8 D4 3600 C16 VLPX". Is this normal and I'm just being stupid/need to mess around in the BIOS or did I get scammed? Sorry if I respond late and thank you in advance if I personally forget to do so!

Have you turned on XMP/AXMP/DOCP in your motherboard's BIOS?

I have a 3900x and I've been told it can handle the higher speeds since it's relatively new. Maybe I just gotta putts around in the BIOS with xpm. Thanks for the information!

I completely forgot that was a setting in the BIOS. I'll give it a look some time soon. Thanks for help!

if it's not turned on (which it is not by default), the RAM will go to its highest default speed, which is often 2133/2400/2666Mhz, as opposed to the XMP speed it can reach.

You have to look for the technology I mentioned before in your motherboard.

In my experience most brands call it XMP/XAMP/A-XMP, ASUS calls it DOCP (on AMD boards)
