LV-672 User’s Manual Introduction
Chapter1 <Introduction>
1.1 <Product Overview>
LV-672 is the motherboard with last Intel desktop technology with Mini-ITX form factor.
Based on Intel® 915G and ICH6R, the board integrates a new Pentium 4 processor 775-pin
socket, DDR2 memory socket, Intel® Graphic Media Accelerator 900 technology, PCI
express interface and Serial ATA 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 800MHz 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® 915G and ICH6R chipset
The Intel 915G integrates DDR2 400/533MHz for memory, and Graphic Media Accelerator
(GMA) 900 technology for new graphic engine. It can provide up to 224MB of frame buffer
when you install over 256MB of system memory. The ICH6R integrates with up to 8 USB2.0
interfaces (6 ports for LV-672), and serial ATA interface with RAID function.
Dual Intel® 82541GI Gigabit LAN
With dual Gigabit LAN with Intel® 82541GI, LV-672 comes with a powerful network function
for the system that requires large transfer data of NAS system or Server platform.
PCI-Express interface
LV-672 integrates a 16x PCI-Express interface, it can provide up to 8GB/ s of bandwidth,
which AGP 8x can only provide up to 2GB/s.
Multimedia interfaces
LV-672 also integrates 5.1channel AC97 audio, mini-PCI interface a nd IEEE1394 port, for
these flexible function, system integrator can built more powerful systems for many
applications.
