Questions about this item

Should I pick the 64GB DDR4 version or a lower-capacity kit for this Z370 board?

The board supports up to 64GB across four DDR4 DIMM slots, so a 64GB kit fills every slot and gives the maximum the chipset allows.

What does the 1000 Mbit LAN figure mean once the board is in a working PC?

The Killer E2500 controller tops out at 1000 Mbit, so real-world throughput will not exceed a gigabit connection even if your router is faster.

How fast can the USB 3.1 Gen 2 Type-C port on the rear panel actually run?

The ASMedia controller drives that port at USB 3.1 Gen 2 speeds, so the practical ceiling is the Gen 2 10 Gbit/s signalling rate.
