Processor
HyperTransport
TM
Technology is a point-to-point link between two devices, it
enables integrated circuits to exchange information at much higher speeds than
currently available interconnect technologies.
• Accommodates AMD Phenom
TM
and later desktop processors (socket
AM3+)
• Supports HyperTransport
TM
(HT) 3.0 interface speeds
This motherboard uses a socket AM3+ that carries the following features:
SB950 (SB)
AMD 990FX
(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 three x16 PCI-Express Gen2 graphics link
• Fully supports ACPI states S1, S3, S4 and S5
• Complies with all relevant Windows Logo Program
(WLP) requirements from Microsoft
®
for WHQL certifi-
cation.
• Supports 16-bit up/down HyperTransport (HT) 3.0 in-
terface up to 5.2 GT/s.
The AMD 990FX Northbridge (NB) and SB950 Southbridge (SB) chipsets are
based on an innovative and scalable architecture with proven reliability and
performance.
