MX-7794 User’sManual Introduction

Product Overview7

Chapter1 <Introduction>

1.1 <Product Overview>

MX-7794 is the motherboard withlast Intel desktop technologywith Mini-ITXform factor.

Based on Intel®945G and ICH7R, the board integrates a newPentium 4processor 775-pin

socket, DDR2 memorysocket, Intel®Graphic Media Accelerator 950 technology, PCI

express interface and SerialATAII with RAID function for a powerful desktop system.

Intel®LGA775 processor

The Intel®Pentium 4 processor nowcomeswith 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 processorwithout pin header on solder side can makeuser 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 technologyfor newgraphic engine. It can provideup 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 MX-7794), and serial ATAII interface with RAID function.

Four Marvell E8053

Four Gigabit LAN with Marvell E8053, MX-7794 comeswitha powerful network function for

the system that requires large transfer data of NAS system or Server platform.

PCI-Express interface

MX-7794 integrates a x16 PCI-Express interface, it can provide up to 8GB/s of bandwidth,

which AGP 8xcan onlyprovide up to 2GB/s.

Multimedia interfaces

MX-7794 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.
