Hi I have a doubt. I have 2 different DDR chips from Micron Technology, both are 4GB capacity with dual channel. But each of them have different die configurations. One has 2 die and the other one has 4 die. Which one should I select? What is the role of the die here?

He guys, Can someone please clarify the following for me: 1. From my basic understanding, laptop motherboards do not use PCIe connectors, so the entire discussion about PCIe 4.0 & 5.0 is irrelevant for laptops. Is this correct? What confused me is what when I look at the tech specs of M.2 NVMe...
