Proper RAM for NUC8i5BEK

I want to install 16GB of RAM and want to make sure to buy the proper model. I see the compatible memory list has this model:

G.Skill F4-2400C16D-16GRS

This is the 2x8GB listed on Newegg for $120:

https://www.newegg.com/Product/Product.aspx?Item=N82E16820232154 G.SKILL Ripjaws Series 16GB (2 x 8G) 260-Pin DDR4 SO-DIMM DDR4 2400 (PC4 19200) Laptop Memory Model F4-2400C16D-16GRS - …

However, they have the 1x8GB for $52

https://www.newegg.com/Product/Product.aspx?item=N82E16820232153 G.SKILL Ripjaws Series 8GB 260-Pin DDR4 SO-DIMM DDR4 2400 (PC4 19200) Laptop Memory Model F4-2400C16S-8GRS - Newegg.com

and the 1x16GB for $100

https://www.newegg.com/Product/Product.aspx?item=N82E16820232155 G.SKILL Ripjaws Series 16GB 260-Pin DDR4 SO-DIMM DDR4 2400 (PC4 19200) Laptop Memory Model F4-2400C16S-16GRS - Newegg.co

Is there any benefit from buying the 2x8GB pack or can I get the cheaper 2 1x8 or 1x16?

If you install only a single SODIMM, you are utilizing half of the processor's capability (i.e. only one of its two controllers) for reading/writing memory. While the processor's caches will make up for this to a certain extent, you are still taking a performance hit going this route. The only time that I would do this is if I plan in the not-too-distant future to add another of these SODIMMs (i.e. going with a single 16GB SODIMM now with plans to expand to two SODIMMs and 32GB at a later date).

When you purchase a packaged pair of SODIMMs, the vendor has validated these SODIMMs and is certifying that they are very well matched to each other. When you simply purchase two SODIMMs with the same part numbers, they may not be as well matched (and indeed may not be as well validated; such is the industry these days). Since we are, in this case, talking about SODIMMs that will go into two separate memory channels, however, this isn't as big a deal as it would be if we were talking about two SODIMMs that are being used on the same memory channel (which is not even possible in the NUC design). Bottom line, you can save the $20 in this case and should not suffer any performance degradation as a result. If you think about it, you would have been paying them $20 to ensure that the two SODIMMs are well matched (and perhaps better validated).

Hope this helps,
