Phenom™ X4 / Phenom™ X3 / Athlon™ X2 / Athlon™ /

Sempron™ processors (socket AM2+ / AM2)

The motherboard supports AMD

®

Socket AM2+ multi-core processors.

It features dual-channel DDR2 1200(O.C.)/1066 memory support, data

transfer rate up to 5200MT/s via HyperTransport™ 3.0 based system bus

and AMD

785G chipset

The AMD

®

785G Northbridge is the latest AMD chipset designed for both

HT1.0 and 5200MT/s HyperTransport™ 3.0 (HT 3.0) interface speed and

external graphics in PCI Express 2.0 standard. It features the integrated

ATI Radeon™ HD 4200 GPU and fully Directx 10.1 compliant.

Dual channel DDR2 1200(O.C.)/1066 support

This motherboard supports DDR2 1200(O.C.)/1066, which provides faster

data transfer rate and more bandwidth to increase memory data transfer

rate and computing efficiency. This enhances system performance in 3D

graphics and other memory demanding applications.

Due to AM3/AM2+ CPU limitation, only one DDR2 1200(O.C.)/1066 is supported per

channel. When four DDR2 1200(O.C.)/1066 DIMMs are installed, all DIMMs run at

800MHz frequency by default for system stability.
