Asus M4A78-EM/1394 - Manual (Page 14)

AMD ® Phenom™ x4 / Phenom™ x3 / Athlon™ x2 / Athlon™ /
Sempron™ processors (socket AM2+/AM2)
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 an 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
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.
Dual channel 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™.
