671T-M (V1.0)
Socket LGA775 und FSB1066/DDR2 667 Motherboard
671T-M is one of the most advance and unique modules of ECS production. It can also support latest Intel® Core™2 Duo/ Celeron D processors, up to 1066MHz FSB,DDR2 667, two serial ATA and 8 USB 2.0 ports for features. With embedded Mirage3 Graphics, 256M share memory and one PCI ExpressX16 slot, all these advance supports, we believe your computer can run with best performance and bring you the great value and enjoyment.

Supports LGA775 Intel processors with HT Technology.
  FSB 1066
Supports the latest 1066MHz front side bus Intel processors
  DDR2 667
Expands memory bandwidth up to 10.7GB/s and supports up to 4GB of memory. Memory access time is dramatically shortened, which leads for extremely quick results.
  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.
SATA RAID allows you to join several hard drives and increase data transfer by separating data (RAID 0) or by keeping 100% secure data duplication (RAID 1). This fulfills a total performance and security purposes that you need for your data.
  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.
  6 Channel High Definition Audio
Integrated 6-channel HD Audio CODEC delivering advanced multi-channel audio and bringing you the experience of home theater-quality sound.

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.
(How to use flash utility).

* means validated by ECS at time of writing. Changes to component or CPU may produce a different outcome. The result shown is for reference only and is subject to change w/o notification.
