Socket G34

G34 socket pinout

G34 was launched on March 29, 2010. It supports 10h and 15h Opteron CPU's. All G34 Opteron CPUs are dual node processors with two NUMA nodes.

K10 Processors

K10 Opteron (Magny-Cours) processors are compatible with the G34 socket. TDP ratings for these processors range between 85 W and 140 W. These processors are not yet supported by coreboot-15h.
