LV-674 User’s Manual Introduction
Chapter1 <Introduction>
1.1 <Product Overview>
LV-674 is the motherboard with last Intel desktop technology with Mini-ITX form factor.
Based on Intel® 945G and ICH7R, the board integrates a new Pentium 4 processor 775-pin
socket, DDR2 memory socket, Intel® Graphic Media Accelerator 950 technology, PCI
express interface and Serial ATA II with RAID function for a powerful desktop system.
Intel® LGA775 processor
The Intel® Pentium 4 processor now comes with a new form factor with 775-pin PLGA
package, for 533/800/1066MHz front-side-bus, 1MB L2 cache, and for 90nm manufacturing
technology, the PLGA processor without pin header on solder side can make user installing
the processor on the socket easier.
Intel® 945G and ICH7R chipset
The Intel 945G integrates DDR2 400/533/667MHz for memory, and Graphic Media
Accelerator (GMA) 950 technology for new graphic engine. It can provide up to 224MB of
frame buffer when you install over 256MB of system memory. The ICH7R integrates with up
to 4 USB2.0 interfaces (4 ports for LV-674), and serial ATA II interface with RAID function.
Four Marvell E8053
Four Gigabit LAN with Marvell E8053, LV-674 comes with a powerful network function for
the system that requires large transfer data of NAS system or Server platform.
PCI-Express interface
LV-674 integrates a x16 PCI-Express interface, it can provide up to 8GB/s of ban dwidth,
which AGP 8x can only provide up to 2GB/s.
Multimedia interfaces
LV-674 also integrates 7.1 channel AC97 audio, mini-PCI interface and IEEE1394 port, for
these flexible function, system integrator can built more powerful systems for many
applications.
