(Note 1) DDR II memory can be overclocked to 888MHz (must be used with a 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.
