HyperTransport™ 3.0 support 




HyperTransport 3.0 technology provides 2.6 times more bandwidth than HT1.0 that 

radically improves system efficiency for a smoother, faster computing environment.

Native DDR2 1066 support 

This motherboard supports native DDR2 1066. It provides faster data transfer rate 

and more bandwidth to increase memory computing efficiency, enhancing system 

performance in 3D graphics and other memory demanding applications. See page 

1-15 for details.

AMD Socket AM2 Athlon™ / Sempron™ 




CPU support

This motherboard supports AMD Socket AM2 Athlon / Sempron processors. It 

features 2000/1600MT/s HyperTransport-based system bus, dual-channel 

un-buffered DDR2 800 memory support, and AMD Cool ‘n’ Quiet™Technology. 

See page 1-10 for details.

64-bit CPU support 

64-bit computing, the next generation technology to replace the current 32-bit 

architecture, delivers advanced system performance, faster memory access, and 

increased productivity. This motherboard provides excellent compatibility and 

flexibility by supporting either 64-bit or 32-bit architecture.

Due to AM2+ CPU limitation, only one DDR2 1066 DIMM is supported per 

channel. When four DDR2 1066 DIMMs are installed, all DIMMs run at 800MHz 

frequency by default for system stability.
