Motherboard Components

Socket G34

G34 socket pinout

G34 was launched on March 29, 2010. It supports 10h and 15h Opteron CPU's[1]. All G34 Opteron CPUs are dual node processors with two NUMA nodes.

AMD Opteron 6100 Series

Processors in the AMD Opteron 6100 Series were designed with the K10 microarchitecture and are compatible with the G34 socket.

Official Source Code and Documentation

AMD Opteron 6200 and 6300 Series

Processors in the AMD Opteron 6200 and 6300 Series were designed with the Bulldozer (6200 series) and Piledriver (6300 series) microarchitectures and are compatible with the G34 socket.

AMD SR5690

The AMD SR5690, also known as RD890S, was released in March 2010 as a powerful system logic for server and workstation platforms. It offers 46 PCI Express lanes, with 42 lanes dedicated to external PCIe devices and 4 for the A-Link Express II interface to AMD's Southbridges like the SP5100 (formerly SB700S). The chipset boasts the latest technologies, including HyperTransport™ 3 and PCIe Gen 2, and its highly integrated, thermally efficient design comes in a compact 29mm x 29mm package.[2]

Custom Parts

Northbridge Fan

This file is designed to work with a Noctua NF-A4x10 fan. If your motherboard is not in a high-airflow server case, the northbridge fan is highly recommended. The fan bracket mounts onto the northbridge heatsink by snapping onto the metal arms that secure the heatsink. The file may need to be edited to accommodate the exact placement of your 40mm fan cable (the provided design has a cable hole at the bottom right position).
