LGA 1851 (codename Socket V1) is a land grid array CPU socket designed by Intel for Meteor Lake-PS, Arrow Lake-S and Arrow Lake-S Refresh desktop processors, estimated to be released in 2024.[1]
The number of contacts has increased, from 1700 (for LGA 1700) to 1851.[2] It uses the same dimensions and cooler mounting hole spacing as LGA 1700, ensuring continued CPU cooler compatibility.
It offers 20 PCIe 5.0 lanes (x16 for the expansion cards and x4 for storage) and an additional 4 PCIe 4.0 lanes for storage. The available PCIe lanes for the expansion cards can now be bifurcated to three devices (x8, x4, x4) instead of two, in case of LGA 1700. Similar to AMD's AM5 socket, it is exclusively on DDR5 SDRAM, dropping support for DDR4 unlike its predecessor (LGA 1700), marking the end of mainstream DDR4 after 10 years.[3][4][5][6]
