GIGABYTE leading technology-Easy Energy Saver 

Featuring an advanced proprietary software design, GIGABYTE Easy Energy Saver is able to 

dynamically adjust CPU power depending on workload, delivering just the right amount of power 

needed for the task. Coupled with Intel’s highly efficient 45nm CPU’s, Easy Energy Saver is able to 

provide exceptional levels of power savings and enhanced power efficiency without sacrificing 

computing performance. 

Intel ® Core 2 multi-core and upcoming 45nm processors 

GA-G31M-ES2L supports Intel latest high performance CPU delivers the most energy-efficient 

performance available today. Based on Intel's Micro Architecture, the Intel multi-core processors with 

4 cores and two shared L2 caches provide the best capability-per-watt solutions and are an ideal 

choice for multi-media enthusiasts and intensive multi-tasking environments. This cutting-edge 

processor offers significant performance boosts and provides an overall more energy efficient 

platform 

Solid Capacitor and Ferrite Core Choke for CPU VRM 

Stable system operation depends upon the quality of CPU VRM (voltage regulator module). 

GIGABYTE adopts Conductive Polymer Aluminum Solid Capacitors and Ferrite Core Choke for CPU 

VRM featuring better electronic conductivity, excellent heat resistance, and ensures a longer lifespan 

for systems in daily operation and boost system stability under extreme conditions. 

DualBIOS - Patented Dual Hardware BIOS Protection 

DualBIOS is a GIGABYTE patented technology that automatically recovers BIOS data when main 

BIOS has crashed or failed. Featuring 2 physical BIOS ROMs integrated onboard, GIGABYTE 

DualBIOS allows quick and seamless recovery from BIOS damage or failure due to viruses or 

improper BIOS updating. 

PCI Express Interface 

Revolutionary PCI Express interface provides scalable bandwidth for multi-purpose usage. PCI-E x16 

interface delivers the utmost graphics experience; PCI-E x1interface delivers twice the bandwidth of 

PCI interface up to 250MB/s for new generation I/O peripheral devices. 

Dual Channel DDR2 1066 by O.C 

Get a jump in memory performance with the advanced technology of DDR2 1066 memory 

architecture by overclocking, which delivers superior performance for the most demanding 

applications.

Specifications 

Intel GMA 3100 

Intel Graphics Media Accelerator 3100 support Microsoft DirectX 9.0 and Windows Vista Aero 

experience. The 3D enhancement of GMA 3100 highly improves the realism and graphics 

performance.. 

SATA 3Gb/s storage interface 

The SATA specification doubles bus bandwidth from 1.5Gb/s to 3Gb/s. Native Command Queuing is 

a new specification that enables out-of-order execution of commands for efficient retrieval of data. Hot 

Plug support allows users to insert and remove hard disk drives without shutting off power to the 

system. 

Gigabit LAN connectivity 

The Gigabit network interface delivers a high speed LAN connection with data transfer rate up to 

1000Mb/s, providing new generation connectivity for the broadband era. Gigabit LAN is ideally for 

seamless internet connection such as streaming audio and video contents

software such as Download Center, @BIOS, Q-Flash, Xpress Install, Boot menu, and Smart Fan. 

BIOS and driver management now becomes much easier and user friendly through GIGABYTE 

Smart features!...more 

Safe 

Safe is the key feature of GIGABYTE S-series motherboards with the following elements: Excellent 

hardware design reinforced BIOS protection through GIGABYTE Virtual Dual BIOS Technology and 

GIGABYTE BIOS Setting Recovery Technology. Unique system software such as Xpress Recovery 

2, PC Health Monitor, HDD S.M.A.R.T., and C.O.M. further strengthen the stability and reliability of 

your PC!...more 

RoHS compliant 

As a member of the global community to look after the environment, Gigabyte complies with the 

European Union's Restriction of use of certain Hazardous Substances (RoHS) directive which limits 

the use of lead, mercury, cadmium and other hazardous substances in electronic products.. From 

components and material selection to production processes, make up of accessories, packaging/color 

boxes etc; GIGABYTE has carefully examined and designed this product to be 100% RoHS 

compliant. GIGABYTE will continue to develop RoHS compliant PC components and commit valuable 

resources to promoting and advancing RoHS directive goals and objectives.
