Question New Ram with same speed as old Ram running at 2133 instead of 2666

So I used to have 2x4GB RAM sticks that I replaced with 2x8GB RAM that are both advertised to run at 2666 speed. The old sticks ran also advertised to run at 2666 and when doing some digging I found out that my computer indeed ran them at 2666 speed. So after replacing them with the new sticks, even though I am getting 16GB of ram, they are only running at 2133 speed. I searched online and a lot of people are saying to enable XMP or DOCP in the BIOS but I tried to do that and don't have the tab or accessibility for any such feature.
My specs are as follows:

System model: ROG Strix
BIOS mode: UEFI
CPU: INTEL i7-9700k
GPU: GTX 1660

Please let me know what I can do to ensure my ram is running at full speed. I know it is possible since my old RAM was able to do it.

The motherboard is ROG Strix GL10CS_GL10CS.
As in this?
ROG Strix GL10CS | Tower PCs | ASUS Global

Maybe the next will show what motherboard they exactly use,

download hwinfo,
install and open it=click run,
close the top window which is the system summary,
in the main window at the left top click "save report",
at the bottom of the next window check "Summary for Clipboard",
after that you'll see what's in the pc,
copy by clicking "copy to clipboard" and rightclick+paste in your next respons
Might be since OEM that they limit accessibility to change things in the bios/uefi.

B360 chipset doesn't support ram overclocking. 2666mhz is max possible on that board.

Can you show screenshots from CPU-Z - memory and spd sections?
(upload to imgur.com and post link)
Where would I go to find that? And I know, I don’t need more than 2666 just that speed is more than enough for me.

Can't really find much with just that somehow, you may seem to know more since updating the bios?

As said might be that Asus limited upgrade options by limiting ram in speed to make sure the possibility of incompatibility would be as slim as possible.

Maybe can make some photo's from the bios and post them here so i can see if the option is there although you seem capable enough of noticing that.

You can use Imgur to post a picture here,use the "img" link.
Click "new post" ->choose "upload images" -> "browse" ->choose the picture and click "open" ->put cursor on the picture that you uploaded->choose "share links" and copy the img link,paste it in your next post.
 
Ok. Your ram supports 2666mhz mode with XMP.
Without XMP it will run automatically at 2133mhz.

Either enable XMP or set ram parameters manually in BIOS. You can see required ram settings for 2666mhz mode in your CPU-Z screenshot (column XMP-2666).

I'm not sure BIOS of your board will provide you options to do this. Show screenshots from your BIOS. Try to find section for setting up ram parameters.

Here is my BIOS. I don't see any speed customization on my ram or anything close to a XMP or DOCP.

Your board has very limited BIOS.
You don't have options for setting up ram parameters manually nor enabling XMP.
Sorry.

Only way to run ram at 2666mhz on your board - if ram has 2666mhz option without use of XMP.

Like this module. See table entry with name JEDEC supporting 2666mhz mode (1333x2).

Is it possible that my version of the BIOS is old? I thought I updated it but maybe I didn't? Let me know. Thanks.
(My current version is GL10CS.311)
 
This is quite common issue with brand name prebuilt systems.
Configuration options get intentionally limited, so user has less chance of screwing things up.

You could change motherboard and install some retail model with full configuration options (also with enabled ram and cpu overclocking), if you wanted to.
