I would like to buy this RAM for my notebook (need 32gb, DDR4 Sodimm 2666MHz), but I have two variants to choose from on Amazon, which appear the same at first glance, but one is "Kit with 2.8gbit" the other "kit with 2, 16gbit".
What do you want to do with the pc anyway? Because 32GB is seldom worth it, 16GB is enough for gaming
The latencies are different. One CL15 and one CL16. CL15 is better.
