CPU

• Supports Socket 775 for Intel® P4 5XX, 6XX, P4EE, Pentium D 8XX and Celeron D processors. PCB 2.2 adds 9XX, Core 2 Duo support.
• Supports FSB 800/533MHz.
• Supports EIST technology.
• Supports Intel® Hyper-Threading technology.
• Supports Intel® Dual Core Technology to 800MHz and up.

MSI Reminds You... • According to the Intel North Bridge 945PL chipset spec, this board supports CPU of FSB 800MHz at maximum by default . However, you may let your board running at FSB 1066MHz (Core 2 Duo CPUs) by overclocking and adjusting the CPU FSB frequency in the BIOS: Enter BIOS setup menu and go to [Cell_Menu] --> [Adjust CPU FSB Frequency]. There you can adjust the value to [266] for the Core 2 Duo E6300/E6400/E6600/E6700 CPUs. Please be noted that this is over-spec, and this overclocking behavior is not recommended and guaranteed. *This is for PCB 2.2 only.
