Questions about this item

How do I verify the board posts and recognises memory after first power-on?

The board will beep once, then the BIOS splash appears showing total DDR4 capacity up to 64 GB at 2133, 2400 or 2666 MHz.

What cables and brackets come in the retail box versus what I must source myself?

The box includes the I/O shield, SATA cables and driver disc; CPU cooler, DDR4 modules, M.2 screws and case standoffs are not supplied.

Which memory speed should I select — 2133, 2400 or 2666 MHz — for a Core i5 build?

All three speeds are natively supported; 2666 MHz gives the highest default data rate without manual tuning.
