This article is part of the CPU socket series

Socket G34 is a 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 channels, two for each die in the 1974 pin CPU package. Socket G34 is available in up to four-socket arrangements, which is a change from the current Socket F CPUs supporting up to eight-socket arrangements. However, four Socket G34 CPUs have eight dies, which is identical to what eight Socket F CPUs have. AMD declined to extend Socket G34 to eight-way operation citing shrinking demand of the >4-socket market. AMD is targeting Socket G34 at the high-end two-socket market and the four-socket market. The lower-end two-socket market will be serviced by monolithic-die Socket C32 CPUs with half the core count as the equivalent Socket G34 CPUs.

Development

Socket G34 originally started out as Socket G3, which used the G3MX to expand memory capacity. Socket G3 and G3MX were canceled altogether, and replaced with Socket G34.

Supported CPUs

Socket G34 supports the K10-based 8- and 12-core "Magny-Cours" Opteron 6100 series CPUs. Socket G34 will also support the upcoming Bulldozer-based 8-core, 12-core and 16-core "Interlagos" CPUs, as well as currently-unnamed CPUs to be introduced in 2012 and 2013.
