Questions about this item

Will the bundled Intel Core Ultra 5 245K processor fit this motherboard without any extra parts?

Yes. The board uses an LGA 1851 socket and the CPU is a Core Ultra Series 2 chip, so they match directly. No separate bracket or adapter is required.

What DDR5 memory speeds can I run on the two DIMM slots and what is the maximum capacity?

The board supports dual-channel DDR5 up to 128 GB. JEDEC speeds from 4400 to 9200 MT/s are listed, and XMP profiles above that are supported when overclocking.

Which M.2 drive lengths will physically fit the two onboard slots?

Both M.2_1 and M.2_2 accept Key M modules in 2230, 2242, 2260 and 2280 lengths. Each slot runs at PCIe 5.0 x4, though M.2_2 shares bandwidth with other controllers.
