(Note 1) DDR II memory can be overclocked to 888MHz (must be used with an 1066MHz FSB processor) through overclocking in BIOS. Go to GIGABYTE's website for more information about the supported DDR II memory modules for this feature.

(Note 2) To use a DDR II 667 memory module on the motherboard, you must install an 800/1066MHz FSB processor.
