Socket G34 is a land grid array CPU socket designed by AMD to support AMD's multi-chip module Opteron 6000-series server processors.

G34 was launched on March 29, 2010, alongside the initial grouping of Opteron 6100 processors designed for it.

Socket G34 supports four DDR3 SDRAM channels, two for each die in the 1944 pin CPU package.

AMD declined to extend Socket G34 to eight-way operation citing shrinking demand of the >4-socket market.
