@Vanadiel​ on the back of the desktop it says <Removed your private data. That private Service Tag shows an Aurora R6 that shipped on July 12, 2017. DELL-Admin>

@Matio farahmandi​ If you look at the Aurora R6 technical specifications, you will see 2400 Mhz is maximum supported speed.

That being said, these systems are OEM and very picky on what memory they accept, so I would highly recommend sticking to the OEM memory list posted above.

If you ordered "a stick" it will likely not work, or cause issues. There's also a limit to memory sizes and a limit to mixing memory modules from different size or vendors.

@Vanadiel​ oh i see, Well I’ve already ordered the memory stick and it’s gonna get here today. The one I got is “TEAMGROUP T-Force Vulcan Z DDR4 32GB Kit (2x16GB) 3200MHz.  “ now I know I can’t use it to its full power but do you think it will still be usable just to give me that extra 16 memory? Or do you think the computer just won’t accept it at all? 

ps thank you so much for the quick response and help I’ve never had this quality of support with anyone else.

@Vanadiel​ ok, that’s very disappointing. I’m still gonna give it a try just in case there is a chance it works. But if it doesn’t I’ll just get one of those recommended above, also which one of those would you say would be the best one? I’m just looking to play heavily modded last generation games.

@Matio farahmandi​ You will not really see a lot of difference between those, but if you are planning on expanding what you currently have, make sure it's the same part# as you want to avoid mixing different modules.

@Vanadiel​  hey there, I just got the ram sticks I ordered online, and they work perfectly. Obviously it’s not running at 3200 but it is capped at the 2400. Now I have 2 sticks of 8gb Kingston memory that I don’t know what to do with. Can I add them on top of the new ram sticks and get an extra 16 gb or will that give me problems?

@Matio farahmandi​ I am amazed it worked to be honest. At this point you might as well add the old sticks to the system, worst case scenario it will not work.

@Matio farahmandi​ yes just put them in. Extra 16GB!
