Unsure of which RAM to get for my 2nd slot.

Hi all

I don't know if this sort of post strictly relates to this thread, but if not then please let me know and I'll delete it. Please also suggest where to re-post though

I have two RAM slots on my B350 motherboard, of which only one is currently being used by this RAM stick https://www.newegg.com/Product/Product.aspx?Item=N82E16820156109 . I overclocked it to 2933MHz and here is the dmidecode output.

I don't know much about RAM overclocking but stuff didn't blow up when I overclocked the RAM so I assume it's okay. If something seems off here and I made a mistake and should revert, please let me know.

Now the real question is, I'm thinking of buying as close to the same RAM stick as possible to avoid incompatibilities. So far I can find these two that come very close:

1. https://www.newegg.com/Product/Product.aspx?Item=N82E16820164016 This is the new 2666MHz PC4-21300 model of the RAM with latency 16-18-18. Please note that my RAM right now has latency 16-16-16. Please let me know if this will cause issues.

2. https://www.newegg.com/Product/Product.aspx?item=N82E16820164013 This is the same RAM as mine I think but with a different model number (BLS8G4D240FSEK). Please let me know if I missed something.

Which one should I buy?
