(socket AM3)
• Supports HyperTransport
TM
(HT) 3.0 interface speeds
This motherboard uses a socket AM3 that carries the following features:
SB850 (SB)
AMD 890GX
(NB)
• One x4 A-Link Express III interface for connection to
an AMD Southbridge. The A-Link Express III is a propri-
etary interface developed by AMD basing on the PCI
Express technology, with additional Northbridge-
Southbridge messaging functionalities. It supports the
PCIe Gen 2 transfer rate of 5 GT/s, and is backward
compatible with the A-Link Express II interface.
• Supports two x16 PCI-Express Gen2 graphics link
• Fully supports ACPI states S1, S3, S4 and S5
• Supports ATI HyperMemory*.
Note: Includes dedicated and shared memory. The amount
of HyperMemory available is determined by various
factors. For details, please consult your AMD CSS
representative.
• Supports 16-bit up/down HyperTransport (HT) 3.0 in-
terface up to 4.8 GT/s.
The AMD 890GX Northbridge (NB) and SB850 Southbridge (SB) chipsets are
based on an innovative and scalable architecture with proven reliability and
performance.
