Will the ASRock B650M-HDV/M.2 boot out of the box with an Intel Core i9-14900K?

Yes. The ASRock B650M-HDV/M.2 natively supports the Intel Core i9-14900K out of the box with factory firmware.

Can the VRM on ASRock B650M-HDV/M.2 handle Intel Core i9-14900K's peak power draw?

Under sustained multi-core heavy load (such as Blender, Cinebench, or unconstrained video rendering), the Intel Core i9-14900K draws up to 253W. The ASRock B650M-HDV/M.2's VRM is rated for only 160W, which will cause MOSFET temperatures to exceed 105°C and induce thermal clock throttling of 25% to 40%.

What RAM memory type is required for Intel Core i9-14900K and ASRock B650M-HDV/M.2?

The ASRock B650M-HDV/M.2 is built exclusively with DDR5 memory slots supporting up to 96GB. You must purchase a DDR5 RAM kit.
