The AMD 800 chipset series is a set of chipsets developed by AMD, released in 2009. The chipset series was revealed in its presentation slides during the AMD Financial Analyst Day 2007 held on December 13, 2007. This chipset series also marks the return of AMD to the workstation/server market after the completion of the ATI acquisition in October 2006 with the first server chipsets.

Lineup

Server

The chipset series is targeted in three markets: the workstation/server market, the desktop market and the notebook market. Current information about the chipset series is very scarce, while the officially published information about the series is the server chipsets with two variants available, the AMD 890S chipset and the AMD 870S chipset, all of them paired with the SB700S series southbridge.^[1] The chipsets were supposed to support the codenamed "Montreal" processor made on 45 nm process, in Socket G3 package, supporting both unbuffered or buffered DDR3 (with Socket G3MX), HyperTransport 3.0 and IOMMU, all of them forming the codenamed "Piranha" server platform. However as a result of shifted strategy, AMD abandoned plans for Socket G3 and G3MX completely and focused to deliver new server platforms. Also for uni-processor server platform, the combination of SR5580 (Originally codenamed "RS780") and SP5100 formed the codenamed "Catalunya" platform.

The codenamed "Fiorano" platform consists of codenamed "Istanbul" six-core processors, while "Istanbul" processors still feature Socket F+ and support dual-channel registered DDR2 memory, the platform supports HyperTransport 3.0 and IOMMU.^[2]

The codenamed "Maranello" platform consists of six-core "Sao Paolo" or twelve-core "Magny-Cours" processors. These two processors support a new socket called Socket G34 with four-channel DDR3 support, with other platform features such as HyperTransport 3.0 and IOMMU support.^[2]

The codenamed "Catalunya" platform consists of codenamed "Suzuka" quad-core processors, featuring Socket AM3 and support dual-channel registered DDR3 memory, the platform supports HyperTransport 3.0.^[2]

The codenames of the chipsets "RD890S", "RD870S" and "SB700S" has also changed to "SR5690", "SR5670" and "SP5100".^[3]

Southbridges

While in the same internal event mentioned above, AMD gave a preview on the features of the SB8xx family of southbridges, as follows:^[4]

"A-Link Express 3.0" now uses four PCI Express 2.0 lanes, providing 2 GB/s bandwidth
Supports C6 power state, which is featured in Fusion processors
Incorporates a Gigabit Ethernet MAC
Supports an integrated clock generator as an optional feature
Support for AHCI 1.2 with SATA FIS–based switching support
Mandatory support for SATA 1.5 Gbit/s, 3.0 Gbit/s, and SATA 6.0 Gbit/s (no support for Sata 6.0 Gbit/s in SB810)
Two embedded 8051 controllers, and one dedicated for DASH compliance
Support for 14 USB 2.0 ports, 2 USB 1.1 ports, and 3 integrated EHCI controllers (no support for USB 3.0 in initial products)^[5]
Supports 5 fan controls, 8 V_in and 4 Temp_in for hardware monitoring

Southbridge issues (SB8x0)

AMD does not provide any SB8x0 errata publicly. Most OSes require patches in order to work reliably.

Windows platform:
- Microsoft KB982091
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
- SATA soft reset fails when PMP is enabled and attached devices will not be detected
