HyperTrasport™ 3.0

3,600 MT/s HyperTransport 3.0

HyperTransport 3.0 supports a variety of new features including AC coupling mode, hot plugging, un-ganging mode and dynamic power management for the support of extended signal transmission distance, typical of backplane and chassis-to-chassis implementations.

Integrated Memory Controller DDR2-1066(AM2/AM2+) Memory Bandwidth

The chip's Integrated Memory Controller can talk to Dual Channels of DDR2 memory at speeds up to 1066MHz. This memory controller has been improved in various ways, among them larger buffers and an improved mechanism for speculative data pre-fetch.
