Memory upgrade E7390

Question

I bought a used Latitude E7390. It has an 8 GB stick of DDR4-2400 /PC4-19200 RAM. I wanted to increase the amount of RAM to 16 GB and bought an additional stick of the 8 GB RAM DDR4-2400. When the additional stick arrived, I opened up the back of the machine and was shocked to learn it only has a socket for 1 stick of RAM, not two like most laptops have. Fortunately, I had another computer that could benefit by the stick I had purchased for the E7390, and I placed it there.  So I checked online for a 16 GB stick and noticed the prices were a bit high for me at this time, but I also remembered that I have a Shuttle DH110SE with two sticks of 16 GB laptop DDR. I know that 32 GB is a lot more than I need in that machine and wondered if I could pull one of those 16 GB sticks out of the Shuttle and place it in the E7390. I checked, and the 16 GB sticks are DDR4-2133 /PC4-17000 RAM.   So, before I open up each machine and move RAM around, I want to know if the DDR4-2133 /PC4-17000 RAM will work in my Dell Latitude E7390? I know it is a little bit slower RAM, but it's increased amount should make up the difference, particularly while multitasking.

The answer likely depends mostly on the CPU you have, since it controls the memory speed.  There's no harm in trying -- it may work particularly with an i3 CPU but may not with an i7.

It has an i7-8650U. In a couple of days, I will try and see if it works. I've got several other jobs going right now including an attempt to speed up a 9 year old extremely sluggish computer with a very slow AMD CPU. I've got it running quite a bit faster by simply cleaning the register, removing temporary files, and uninstalling old software no longer needed. Right now I'm updating it's software and the last thing I intend to do is run tweaking.com's Windows Repair on it. Might not do it any good, but should not harm it.

I'm sorry ... somehow, when I go to private messages and try to see what that message says, the 'Reply Box' sits right on top of the private message and I cannot see and read it. Any suggestions on how I can actually read 'Private Messages'?

It could be due to an error on the page. Is it working fine now? Would you be able to share an image of that?

I've tried Edge, Brave, and Google and all place the reply box on top of the message.
