This article from MiniTool partition editor site will tell you the basic knowledge about CPU socket LGA 2066 together with its compatible processors and motherboards. You can also learn more related info on this website.

CPU Socket LGA 2066

Intel LGA 2066 replaces Intel’s LGA 2011-3 (R3) socket in the desktop platforms, including high-end desktop (HEDT) and workstations, based on the X299 “Basin Falls” and C422 chipsets. While Intel LGA 3647 CPU socket replaces the LGA 2011-3 (R3) in the server platforms based on Skylake-SP (Xeon “Purley”).

Some Basic Information About LGA 2066 Socket

First of all, LGA 2066 is of LGA type of course. Then, its chip form factor is flip-chip land grid array (FCLGA). This socket has 2066 contact pins and adopts Intel QPI (QuickPath Interconnect) DMI (Direct Media Interface) 3.0 FBS protocol. Finally, its supported memory type is DDR4.

  • Flip-chip is a method for interconnecting semiconductor devices like an integrated circuit (IC) or monolithic IC chips and microelectromechanical systems (MEMS) to external circuitry with solder bumps that have been deposited on the chip pads. Flip-chip is also called a controlled collapse chip connection or its abbreviation, C4.
  • FSB, front-side bus, is a kind of computer communication interface (bus) that was often used in Intel-chip-based computers during the 1990s and 2000s.

LGA 2066 CPU List

All high-end desktop processors that are compatible with the socket LGA 2066 require Intel X299 chipset to work; while all workstation processors that are compatible with the socket LGA 2066 require Intel C422 chipset to work. Therefore, the X299 chipsets are strictly limited to only work with high-end CPUs; while the C422 chipsets are strictly limited to work with workstation CPUs only.
