<div>I ordered this laptop with 4gb ddr4 ram but I want to buy other 4gb. I chose Crucial but and I found 2 identical models, one shows "SR x8" and the other shows "SR x16", can you tell me the difference?</div><div>If you suggest other models, please write it :)

    Hi,
    I think it's the manufacturing process and not related to speed, for compatibility as I said before, after receiving the laptop check the specs of the RAM installed and get the matching module and install.

    Hi,
    You can install 2400MT/s module to match the original RAM but I guess both will run at 2133MT/s as the Motherboard supports the maximum speed of 2133MT/s.

    Your CPU's data sheet is here:
    (paste this after the .com/ part of Intel's website) content/www/us/en/products/processors/core/i5-processors/i5-7200u.html

    @brummyfan2 gave the best advice, which is to simply buy an exact duplicate of the RAM that is in your machine already. This will meet your goal very nicely.

    Your laptop will only take a total of two sticks. Just go for single rank memory and you'll be fine. Don't confuse it with single-channel, by the way. Channel and rank are two different things. Your CPU will support dual-channel memory, which is a huge improvement over single-channel, so you should pay attention to that. But rank--just get single rank.

    Alternatively, to look at your upgrade options now that your machine has presumably been delivered, you can turn on your machine and go to Crucial's website and run their system scanner. Whatever you do, matching is always the best practice because any mismatch of specs will cause problems, whether it's the clock speed, CAS latency (CL), or what have you. That's why they sell kits of matched sticks.

    Hi,
    Could you please provide the details of the memory module installed in your laptop, you can find the details on the module itself or use CPU-z to find out the details.

    I'd just need the difference between the SR x8 and SR x16... If it stands for something like memory's speed or compatibility with the ram's slot, maybe I could solve the issue by my self.

    True, it is about compatibility in some ways.
    SR = single rank (as opposed to dual rank or quad rank)
    For context, you could replace four 4GB single-rank modules with a single 16GB quad-rank module. The question then would be, how many memory ranks can your operating system address? This is really a question for servers, not your laptop.

    If you look at a memory module, you can see it has several chips on it. The x8 and x16 are classifiers for those chips.

    In short, SRx8 and SRx16 are references to the entire module's density of chips.

    What's your model number? (E5-575G-????)

    I checked the ram and it's SR x16, I'd want to buy this: https://www.amazon.it/gp/product/B01N79H5HV/ref=s9u_simh_gw_i1?ie=UTF8&pd_rd_i=B01N79H5HV&pd_rd_r=d6318721-c0ab-11e7-8c5a-83f4c7b61017&pd_rd_w=IrhO6&pd_rd_wg=zt5Sg&pf_rd_m=A11IL2PNWYJU7H&pf_rd_s=&pf_rd_r=BCCFP74G1F3B3ZEFDV1C&pf_rd_t=36701&pf_rd_p=36fa4a69-84d8-4fe0-81dd-b696574370ac&pf_rd_i=desktop&th=1
    Should I buy the 2400 MT/s or 2133 MT/s?
    These are my ram's specs (by cpu-z):https://imgur.com/a/rstJg
