  • Introduction


    Based on the new Intel P43 chipset, GA-EP43-DS3R delivers a record setting 1600MHz Front Side Bus by overclocking for the latest Intel® Core™ 2 multi-core processors, including 45nm CPUs. With supporting dual channel DDR2 up to 1200MHz by overclocking, GA-EP43-DS3R motherboard provides the highest levels of performance and maximum overclocking potential. GA-EP43-DS3R delivers several advanced GIGABYTE innovations including the DES Advanced, Ultra Durable 2, Ultra TPM design which provide optimized power savings, ultra cooling and ultra secure data protection.
  • Qualified for Windows® 7
    The motherboard qualified for WHQL (Windows Hardware Quality Labs) certification of Windows 7 from Microsoft®, setting the standard for future Windows 7 certified motherboards...more
  • Smaller, Faster and More Efficient
    Carte mère pouvant être associée à un processeur Intel 45nm CPUs pour offrir des performances optimales et ce, au travers d'une gestion d'énergié contrôlée et optimisée.
  • Supports Dual Channel DDR2 1200+
    Experience the advanced technology of DDR2 1200+ memory, featuring faster speeds and higher data bandwidth, which delivers superior performance for the most demanding applications.
    * DDR2 1200+ is supported with combination of AM3 processors and qualified memory modules, please refer "Memory Support List" for detail memory support information.
  • Interface graphique PCI-E 2.0
    L'interface PCI-E 2.0 double la bande passante de la norme PCI-Express standard, en passant de 2.5 Gbit/s à 5 Gbit/s, un connecteur x32 pouvant transférer jusqu'à 16 GB/s de données.


  • Dynamic Energy Saver Advanced
    GIGABYTE Dynamic Energy Saver Advanced provides better energy saving capabilities and enhanced system performance. GIGABYTE Dynamic Energy Saver Advanced is the world’s only motherboard energy saving technology with hardware-based Dynamic 4-Gear* Switching. With support for VRD 11.1, GIGABYTE's DES Advanced allows the motherboard to switch to 1 Gear phase switching during idle, allowing for a dramatic increase in power savings.

    GIGABYTE has also retooled Dynamic Energy Saver to allow overclockers to experience the benefits of multi-gear power phase switching while overclocking, providing ultra stable, ultra smooth overclocking performance.
    * The 4-Gear feature may vary by model. Gear 1 phase switching requires 45nm processors with PSI signal enabled.


  • Ultra TPM - Le plus haut niveau de protection des données
    TPM function is optional due to different regional policy
    • Maximum level of data protection with 2048 bit encryption
    • Security, manageability and flexibility that surpasses software-based encryption
    • Portable User Key to protect data when away from your system
    • Additional backup of user key in BIOS in case of misplaced key
    • After creating the password(s) and key(s) associated the TPM, be sure to store them in a secure location and back them up. Loss of the password(s) or the key(s) will render the files encrypted via the TPM unable to be cracked or read.
    • Though the TPM delivers the latest data security technology, it does not guarantee data integrity or give hardware protection. GIGABYTE is not liable for loss of encrypted data as a result of hardware damage.
    (Note)If you want to uninstall the Ultra TPM utility, be sure to insert the USB flash drive containing the TPM key into your computer before the uninstallation.

  • Adjusts power consumption automatically according to your LAN cable lengths, up to 10% power savings.
  • Gestionnaire de control Overvoltage (IC)
    Hardware Overvoltage Control ICs which provide more voltage control options than before for the CPU North Bridge and memory. The overvoltage controllers also provide hardware linear real-time voltage control. In addition, Hardware Overvoltage Controller ICs also allow for much finer voltage control, allowing power users to adjust voltage in as little increments as 20mV for better overclocking performance.
