AMD 790FX & SB600 Chipset
 Desktop PC platforms based on the Intel® X48
Express Chipset, combined with either the Intel® Core™2 Duo, Intel®
Core™2 Quad or Intel® Core™2 Extreme processors establish a new standard
for performance. Designed to push the limits, the Intel X48 Express
Chipset supports the new Intel® QX9770 Core™2 Extreme processor with
1600 FSB, dual-channel XMP 1600 MHz DDR3 memory, next generation dual
X16 PCI Express 2.0 and Intel® Extreme Tuning to extract the maximum
platform performance.
