945GCT-M3 (V3.0)
Supports Intel® Core™ 2 Duo motherboard
The 945GCT-M3 motherboard supports the most powerful and energy efficient Intel® Core™2 Duo processors. It's a cool and stable platform that delivers extreme performance, minimum noise and maximum power saving!

  Core 2 Duo
The processor is manufactured on Intel's 65nm fab process, regardless of L2 cache size, resides in an LGA775-style socket and runs up to 1333MHz front-side bus. Its power consumption is really much lower than previous Intel desktop chips.
  FSB 1066
Supports the latest 1066MHz front side bus Intel processors
  FSB 800MHz
Supports the 800MHz front side bus Intel CPUs.
  64bit support
Allows platforms to access more memory and larger files. Large memory intensive applications can see dramatic performance increases .
  Dual Channel DDR2 533
Supports latest Dual-channel DDR2 533/400 DIMM and mainstream Dual-channel DDR400/333 DIMM. Users can use either DDR2 or DDR memory modules.
  PCI Express
PCI Express Lite is an ECS patent design. To make use of the PCI Express interface, it can not only upgrade the expansion of PCI-E x16 graphics card but also support the Quad-Display function.
  Serial-ATA II
Doubles the transfer speed of SATA, running at speed up to 3.0Gb/s, and fully compatible with the soon-to-be-released SATA HDD, CD-ROM and other cutting-edge devices.
  8-Channel Audio
Enable premium home theater experience through the PC,with support for all major audio formats.
  Giga LAN
Delivers transfer speed ten times faster than conventional 10 / 100 Ethernet connections, supporting a high transfer rate up to Gigabit/s. Gigabit LAN is the networking standards for the future and is ideal for handing large amount of data such as video, audio, and voice.
  Certified For Windows Vista
The latest generation Microsoft O.S., delivers better personal productivity and digital entertainment on your PC through its improved reliability, security, and performance.

Please read the notes carefully before updating BIOS.
1.Do not update the BIOS if the system is running fine. Unsuccessful BIOS flash may cause the system fails to boot up. The manufacturer is not responsible for any BIOS flash failure.
2.Make sure your M/B PCB version number first, and then read the updated description & special note carefully to check if the new BIOS version patch pertain to your current problem.
(How to recognize the M/B PCB version)
3.Please DO NOT reboot system,unplug power supply and remove battery during BIOS update process.
4.It is recommended to use the updated flash utility included in each BIOS download package.
