GeeCoolThe 10980XE only works on X299 boards: LGA2066 socket, quad-channel DDR4 up to 2933MHz. New X299 boards are discontinued, so you're shopping used at still-inflated prices. When picking one, focus on VRM quality (this CPU draws 165W under load; avoid entry-level) and whether the BIOS has been updated for this CPU — many used boards need a flash before they'll POST.
Populate all four memory channels or follow the board's manual; running two sticks cuts bandwidth noticeably.
