Chapter1 <Introduction>
1.1 <Product Overview>
2807680 is the motherboard with last Intel desktop technology with Mini-ITX form factor.
Based on Intel®Q965 and ICH8DO, the board integrates a new Core 2 Duo processor
775-pin socket, DDR2 memory socket, Intel®Graphic Media Accelerator 3000 technology,
Serial ATA II with RAID function for a powerful desktop system.
Intel®LGA775 processor
The Intel®Core 2 Duo processor now comes with a new form factor with 775-pin PLGA
package, for 533/800/1066MHz front-side-bus, 4MB L2 cache, and for 65nm manufacturing
technology, the PLGA processor without pin header on solder side can make user installing
the processor on the socket easier.
Intel®Q965 and ICH8DO chipset
The Intel Q965 integrates DDR2 533/800/1066MHz for memory, and Graphic Media
Accelerator (GMA) 3000 technology for new graphic engine. It can provide up to 384MB of
frame buffer when you install over 1GB of system memory. The ICH8DO integrates with up
to 6 USB2.0 interfaces , and serial ATA II interface with RAID function.
Flexible Extension Interface
The board provides one PCI-slot for graphics card, it also can support PCI-slot for LAN card
or other devices. The board also provides mini-PCI socket.
