The M4A78-E Computer Motherboard from ASUS is a computer motherboard that supports AMD AM3 CPUs and up to 16GB of DDR2 memory, up to 1300MHz in speed. The motherboard boasts PCI Express 2.0 slots, a Gigabit LAN port, integrated audio, FireWire and USB peripheral ports, and an eSATA port. Integrated drive controllers support up to 2 internal PATA and 5 internal SATA drives.
Supports AMD Socket AM3 multi-core processors, including Phenom II, Athlon II, and Sempron 100 processors, which feature L3 cache for superior overclocking capabilities, advanced 45nm manufacturing, and reduced power consumption
Also supports older AMD Phenom X4, Phenom X3, Athlon X2, Athlon, and Sempron processors that use the Socket AM2+ and AM2
The AMD 790GX/SB750 chipset, which is optimized for multi-core CPUs, supports 5200MT/s HyperTransport 3.0 interface speed and PCI Express 2.0 x16 graphics cards
Native support for overclocked DDR2 1300MHz memory, which supports a faster data transfer rate and increased bandwidth when compared to slower memory. The motherboard also supports 1200MHz (O.C.), 1066MHz, 800MHz, and 667MHz memory
Supports PCI Express 2.0 devices, which deliver double the speed and bandwidth when compared to standard PCI Express devices
SidePort Memory, an individual onboard DDR3 memory serving as a memory buffer for integrated graphics, is supported by this motherboard. SidePort Memory does not tax the CPU, allowing you to get better performance from integrated graphics
Supports ATI Hybrid CrossFireX, which allows you to use the motherboard's integrated graphics alongside a dedicated graphics card to increase frame rates and enhance graphics
ATI CrossFireX technology boosts image quality and rendering speed, and supports anti-aliasing, anisotropic filter, shading, and textures. You'll be able to adjust display configurations, tweak 3D settings, and check effects from the ATI Catalyst Control Center
8+1 Phase Power design unleashes the AM3 CPU's potential, delivering high power efficiency for overclocking. High-quality power components work to lower system temperature, resulting in a longer lifespan for components. The motherboard even boasts an extra phase power dedicated to the integrated memory/HT controller
ASUS Anti-Surge protection protects the motherboard and connected devices from damage caused by power surges
ASUS TurboV allows you to overclock your system without exiting or rebooting your operating system, all from a user-friendly interface. It suggests the best overclocking settings for different scenarios
