The AMD 9-Series Chipset is a set of chipsets developed by AMD, released in 2011. The chipset series uses the same silicon as AMD's previous 8-Series chipset however it is targeted at the socket AM3+ platform, including the Bulldozer line, while the 800 series is targeted at the socket AM3 platform. This allows consumers to easily identify the platform through the chipset name. In support of AM3+ CPUs, AMD has validated the 9-Series chipset for use with HyperTransport 3.1 (up to 6.4GT/s). They also worked with NVIDIA to bring SLI support to this chipset series.[1] AMD OverDrive is supported for simplified overclocking.

Southbridge
The SB950 is the companion southbridge that provides I/O support. It provides the following additional capabilities:
- RAID 0, 1, 10, 5 support
Southbridge issues (SB9x0)
- Linux platform:
- HPET operation with MSI causes LPC DMA corruption on devices using LPC DMA (floppy, parallel port, serial port in FIR mode) because MSI requests are misinterpreted as DMA cycles by the broken LPC controller[3]
- Enabling multiple MSI vectors for the SATA controller when three or more SATA ports are used results in loss of interrupts and system hang.
