Macs and RAM

So my entry level 1080p (

) 2017 iMac has 2x4GB 2133Mhz modules. I've noticed that the other iMacs in the lineup have 2400Mhz RAM and that all the RAM I see being sold online for Macs seems to be 2400Mhz.

In "About this Mac" in MacOS under RAM it says that my machine "accepts 2 2133Mhz memory modules". While I'm sure that 2400Mhz modules will work, though perhaps at 2133Mhz only, I'm wondering what the deal is? How come my entry level Mac has slower RAM?
Can I use the 2400Mhz stuff? Will it run @ 2400?
Thanks!

I'm still doing it myself. I'm not paying somebody to do a 40 second job for me.

I'll just do it once the warranty runs out.

Can someone answer my question re: compatibility with 2400Mhz RAM and what not?

It's not a 40 sec job on that model. You have to remove the display panel. As for the 2400 it isn't listed anywhere on official apple sources that it is supported nah. As you already know you can go upto 16gb though

I just looked at the back of my iMac and I don't have the little RAM door thingy

I thought I had it. Super depressing.

Yer You need to remove the Display Panel and VHB (Very high bond) strips, then replace them. Not sure if they are readily available to non Apple places. Ifixit may have them.

EDIT: Just had a quick look and they do sell the strips, but I can only find them as part of a €300 kit

For those that get the South Park reference, all this information makes me a very sad panda. I guess this thing will forever have 8GB of slow DDR4...
