Questions about this item

Should I choose the combo with the Ryzen 7 9700X or buy the Crosshair X870E Glacial board alone?

The listing is a fixed bundle containing both the ROG Crosshair X870E Glacial motherboard and the Ryzen 7 9700X processor. No separate board-only option is offered in this SKU.

What does the 8600 MT/s memory figure mean when I install the included Ryzen 7 9700X?

With a Ryzen 9000 series CPU such as the 9700X the board supports DDR5 up to 8600 MT/s when overclocked, or 8200 MT/s at its standard overclocked profile.

What does the USB4 40 Gbps interface cap in real use?

The two rear USB4 Type-C ports run at 40 Gbps and carry DisplayPort video, PCIe data and USB 3 traffic simultaneously, so a single fast SSD or dock can saturate the link.
