AMD® Socket AM2+/AM2 Phenom™ x4 / Phenom™ x3 / Athlon™ x2 / Athlon™ / Sempron™ CPU support This motherboard supports AMD® Socket AM2+ multi-core processors. It features dual-channel DDR2 1066 memory support and accelerates data transfer rate up to 5200MT/s via HyperTransport™ 3.0-based system bus. It also supports AMD® Cool 'n' Quiet Technology. AMD® 780G chipset The AMD 780G Northbridge is the latest AMD chipset designed for both HT1.0 and HT 3.0 interface speed. It features the future mainstream Hybrid CrossFire technology that significantly optimizes your 3D performance. HyperTransport™ 3.0 support 5200 MT/s HyperTransport™ 3.0 technology provides 2.6 times more bandwidth than HT1.0 that radically improves system efficiency for a smoother and faster computing environment. AMD Cool 'n' Quiet Technology This motherboard supports the AMD Cool 'n' Quiet technology which monitors system operation and automatically adjusts CPU voltage and frequency for a cool and quiet operating environment. DDR2 1200(O.C.) support To attain top performance, ASUS engineers have successfully unleashed DDR2 1200(O.C.) MHz to meet the higher bandwidth requirements of the latest operating system, 3D graphics, multimedia, and Internet applications. • Due to AM3/AM2+ CPU limitation, only one DDR2 1200/1066 DIMM is supported per channel. When four DDR2 1200/1066 DIMMs are installed, all DIMMs run at 800MHz frequency by default for system stability. • We recommend that you install the DDR2 1200 memory modules on the yellow slots for better performance. • Ensure that you download the latest BIOS version at www.asus.com and purchase the memory modules on the ASUS official Memory Qualified Vendors Lists (QVL). Hybrid CrossFireX™ support ATI Hybrid CrossFireX™ technology greatly boosts graphics performance with an onboard GPU and a discrete graphics card. • Hybrid CrossFireX is supported by Windows® Vista OS only. • Refer to www.amd.com for the discrete GPUs which support Hybrid CrossFireX™. 1-2 Chapter 1: Product introduction
