This article is part of the CPU socket series

LGA 2066, also called Socket R4, is a CPU socket by Intel that debuted with Skylake-X and Kaby Lake-X processors in June 2017.[1] It replaces Intel's LGA 2011-3 (R3) in the performance, high-end desktop and Workstation platforms (based on the X299 "Basin Falls" and C422 chipsets), while LGA 3647 (Socket P) replaces LGA 2011-3 (R3) in the server platforms based on Skylake-SP (Xeon "Purley").

Compatible processors[edit]

High-End Desktop (HEDT)[edit]

All of these CPUs require Intel X299 chipset to work. So, C422 chipset are strictly limited to work with workstation processors only.

Kaby Lake-X[edit]

Kaby Lake-X processors were discontinued in May 2018. Starting October 2019, BIOS updates for most of the X299-based motherboards removed support for Kaby Lake-X processors.[2]

Workstation[edit]

All of these CPUs require Intel C422 chipset to work. So, X299 chipset are strictly limited to work with desktop processors only . Take note that that certain types of Xeon processors will not work on this socket . Skylake-P will not work.
