The Intel D850EMV2 is a motherboard that supports the Pentium 4 processor using the 478 pin socket. The board can support both 400 and 533 megahertz frequencies on the system BUS, depending on the individual specifications of the processor. The requirements for RAM, power supply, jumpers, video cards, audio and various input and output devices allow for some variation but the base specifications must be complied with for completing a PC with the Intel D850EMV2 motherboard.
Memory
Four RAM slots are present on the motherboard to allow the RAM to operate in two individually configured channels. The minimum supported memory is 128 megabytes, while the maximum is set at 2 gigabytes. Both the PC600 and PC800 speeds of RAM are compatible.
Power
The motherboard requires a 20-pin ATX main connector with an additional four-pin auxiliary power connection. The two separate connections combine to allow additional 12-volt current to reach the board, and aids in monitoring the voltage regulator for the processor.
Video
An AGP graphics card can be used for video. It operates at 1.5 volts and must be 4x. The standards are specified in the 2.0 standards for AGP cards. It is a safety hazard to use cards that do not conform to the 2.0 standards because the physical construction differs and may not fit on the board correctly. Alternatively, a PCI card may be used for video if the BIOS settings are changed for the computer to recognize the location of the card.
Audio
The Intel D850EMV2 contains integrated audio that uses the controller hub on the board and supports various analog devices. The on-board audio can be disabled through the BIOS if a separate PCI card is used instead. The AC97 audio codec creates high-definition audio on the motherboard.
Inputs/Outputs
A notable addition to the D850EMV2 is the ability to recognize faster transfer speeds on ATA devices, up to 100MB per sec. The hard drives used will need to have additional requirements such as a faster speed. The board also has Intel Application Accelerator built in, which improves the performance of the system by speeding up the load time for the operating system, speeds up data caching and allows hard drives of 137GB and beyond.
