Hi y'all. I would like to get the best ram for my Laptop. What's confusing me is that I'm not really sure what model my laptop is. According to the Dell website, the best fit for my model is the 15 5000, seeing as my laptop has an i5 7200U CPU, but according to the person I bought it of off and the Crucial system scanner its a 15 5567. Also on the I5 7200U specs, the fastest ram speed is 2133MHz, but the ram the laptop came with was 2400MHz. Also side question should I get a pair of 2133MHz instead of buying another 2400MHz one?

You proposed buying "another 2400Mhz"..... that would also be "mixing and matching".

Even if you bought the exact same module that you currently have installed, there's no guarantee that it would 'play nice' with your existing RAM.
In theory, there shouldn't be any issues at all. In practice, that's not always the case.

Like I said, I'd suggest finding either an identical module or the closest you can (match speed & timings) and see what happens. It won't damage anything if it doesn't work; it'll either work, or it won't.

Just make sure you understand the refund policy of wherever you buy from.

15 5000 is the "series", the 15 5567 is the specific model you have.

Run CPU-Z https://www.cpuid.com/softwares/cpu-z.html
And under the "SPD" tab, it'll tell you specifically what RAM you have - and how many slots are populated.

"Mixing & matching" RAM can be problematic (a little less so in laptops for whatever reason) but, if you only have one slot populated, I'd suggest adding to it.... provided you purchase from a store with a reasonable return policy (ie if it doesn't work for you, you can get your money back).

I've seen specs just for the 15 5000, so I thought it was a different model. I didn't know CPU-Z could tell you that. I just opened the laptop up and looked up the ram. I wouldn't never risk mixing and matching
