This motherboard is bundled with a dual core processor selected for FSB1333/2.66 GHz processor, ASRock, please do not remove the stickers on both sides of the CPU socket on the motherboard. If the stickers are damaged or removed, or bear the word "VOID", ASRock is not responsible for the after service of this processor. Installing the memory modules (DIMM) 2Core1333DVI-2.66 G motherboard provides four 240-pin DDRII (double data rate II) DIMM slots and supports dual channel memory technology. Dual-channel configuration, you must install identical (same brand, speed, size and type of chip) DDRII DIMM pair in the slots of the same color. In other words, you must install identical DDRII DIMM pair in dual channel a (DDRII_1 and DDRII_3; Yellow slots, See p. 10 No. 7) or identical DDRII DIMM pair in dual channel b (DDRII_2 and DDRII_4, Orange slots, See p. 10 of Danube) so that it can be activated double technology memory channel.

2Core1333-2.66G motherboard provides two 240-pin DDRII (Double Data Rate) DIMM slots, and supports Dual Channel Memory Technology. For dual channel configuration, you always need to install two identical (the same brand, speed, size and chip-type) memory modules in the DDRII DIMM slots to activate Dual Channel Memory Technology. Otherwise, it will operate at single channel mode.Jumpers Setup: The illustration shows how jumpers are setup. When the jumper cap is placed on pins, the jumper is “Short”. If no jumper cap is placed on pins, the jumper is “Open”. The illustration shows a 3-pin jumper whose pin1 and pin2 are “Short” when jumper cap is placed on these 2 pins

This motherboard supports Untied Overclocking Technology, which means during overclocking, FSB enjoys better margin due to fixed PCI / PCIE buses. Before you enable Untied Overclocking function, please enter “Overclock Mode” option of BIOS setup to set the selection from [Auto] to [CPU, PCIE, Async.]. Therefore, CPU FSB is untied during overclocking, but PCI / PCIE buses are in the fixed mode so that FSB can operate under a more stable overclocking environment.

To prevent electrical shock hazard, disconnect the power cable from the electrical outlet before relocating the system.When adding or removing devices to or from the system, ensure that the power cables for the devices are unplugged before the signal cables are connected. if possible, disconnect all power cables from the existing system before you add a device.Before connecting or removing signal cables from the motherboard, ensure that all power cables are unplugged.Seek professional assistance before using an adapter or extension cord. These devices could interrupt the grounding circuit.Make sure that your power supply is set to the correct voltage in your area. If you are not sure about the voltage of the electrical outlet you are using, contact your local power company.If the power supply is broken, do not try to fix it by yourself. Contact a qualified service technician or your retailer.

The integrated dual Gigabit LAN design allows a PC to server as a network gateway for managing traffic between two separate networks. This capability ensures repaid transfer of data from WAN to LAN without any added arbitration or latency.High Definition Audio Enjoy high-end sound quality on your PC! The onboard 8-channel HD audio (High Definition Audio, previously codenamed Azalia) CODEC enables high-quality 192KHz/24-bit audio output, jack-sensing feature, retasking functions, and multi-streaming technology that simultaneously sends different audio streams to different destinations. You can now talk to your partners on the headphones while playing multi-channel network games.Green ASUS

Make sure that the motherboard supports the CPU. (Go to GIGABYTE’s website for the latest CPU support list.)Always turn off the computer and unplug the power cord from the power outlet before installing the CPU to prevent hardware damage.Locate the pin one of the CPU. The CPU cannot be inserted if oriented incorrectly. (Or you may locate the notches on both sides of the CPU and alignment keys on the CPU socket.)Apply an even and thin layer of thermal grease on the surface of the CPU.Do not turn on the computer if the CPU cooler is not installed, otherwise overheating and damage of the CPU may occur.Set the CPU host frequency in accordance with the CPU specifications. It is not recommended that the system bus frequency be set beyond hardware specifications since it does not meet the standard requirements for the peripherals. If you wish to set the frequency beyond the standard specifications, please do so according to your hardware specifications including the CPU, graphics card, memory, hard drive, etc.

The TPS is intended to provide detailed, technical information about the board and its components to the vendors, system integrators, and other engineers and technicians who need this level of information. It is specifically not intended for general audiences. The D810E2CA3 board supports either an Intel Pentium III processor (FC-PGA package), or an Intel Celeron processor (PGA package). The system bus speed is automatically selected. The board supports the processors listed in Table 4.

USB Support The desktop board has two back panels USB ports. You can connect two USB peripheral devices directly to the computer without an external hub. To attach more than two devices, connect an external hub to either of the built-in ports. The desktop board supports the Universal Host Controller Interface (UHCI) and takes advantage of standard software drivers written to be compatible with UHCI. PCI Enhanced IDE Interface
