Description:

AMD SR5650

The chipset, previously known as RD870S, is a powerful system logic designed for the server/workstation platform. The SR5650 boasts 26 PCI Express® (PCIe®) lanes, with 22 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 is also equipped with the latest HyperTransportTM 3 and PCIe Gen 2 technologies, delivering exceptional performance in a compact 29mm x 29mm package.

Key Features:

1. CPU Interface: Supports up to 5.2 GT/s HyperTransport 3.0 interface with various frequency options, compatible with AMD server/workstation and desktop processors through sockets F, AM3, G34, and C32. Additionally, it supports LDTSTOP interface and CPU throttling.
2. PCI Express® Interface: Fully compliant with PCIe Gen 2 (version 2.0), providing optimized peer-to-peer and general-purpose link performance. The chipset supports 22 PCIe Gen 2 lanes and a revision 1.26 compliant IOMMU implementation for address translation and protection services.
3. A-Link Express II Interface: Offers a proprietary x4 interface to connect with AMD Southbridges, featuring additional Northbridge-Southbridge messaging functionalities.
4. Multiple Processor Support: Accommodates multiple-socket configurations for up to 8 processors on the same system.
5. Power Management Features: Supports ACPI states S1, S3, S4, and S5, AMD PowerNow!TM technology, and dynamic lane reduction for PCIe interfaces, ensuring efficient power consumption.
6. PC Design Guide Compliance: Complies with all relevant Windows Logo Program (WLP) requirements from Microsoft for WHQL certification.
7. Comprehensive Testing Capability: The chipset boasts various test modes and capabilities, achieving a high fault coverage and low Defect Per Million (DPM) ratio.
8. Packaging: Single-chip solution in 65nm, 1.1V CMOS technology, with a flip-chip design in a 29mm x 29mm 692-FCBGA package.

The SR5650 chipset is supported by a range of operating systems, including Windows Server® 2003, Windows Server® 2008, Red Hat Enterprise Linux, SUSE Linux, and Solaris. It also offers ACPI support, full write combining support, and extensive power management features.
