The Intel® X48 Express Chipset is the latest chipset designed to support the next generation 45nm CPU in high-end desktop and workstation platform; and up to 8GB of dual-channel DDR3 1066/800 MHz or DDR2 800/667 MHz memory architecture. It also supports 1600/1333/1066/800 FSB (Front Side Bus), fully dual PCI Express x16 graphics and multi-core CPUs.

Pin-Fin Thermal Module - New Generation Heat-disspating Design - Compare with traditional stacked-fin heatpipe solution, the new generation pin-fin thermal design result in better thermal performance, which enlarges the “heat-exchange” surface area surface and breaks the "Boundary-layer" phenomenon for effective airflow. The Pin-Fin Thermal Module is the most efficient thermal system there is on the motherboard.
