The P4VXAS is an Intel motherboard produced by Elitegroup Computer Systems. This motherboard, which was introduced in 2003, supports a variety of now-outdated computer hardware systems including AGP graphics, Intel socket 478 processors and single-channel SDRAM memory. This motherboard does provide a substantial number of expansion slots, however, as well as support for USB 1.1 and IEEE 1394a data connections.
Processors
The P4VXAS uses the LGA 478 processor socket to support three basic types of Intel processors. The board supports 12 Pentium 4 processor models with speeds ranging from 1.6 to 2.8 GHz. This board also supports five Celeron processor models with speeds between 1.7 and 2.53 GHz.
Features
This motherboard supports SD-RAM modules in single-channel mode. It provides a total of three 168-pin DIMM sockets designed for RAM modules operating at 3.3 volts. The P4VXAS supports a total of 3 GB of memory using registered memory, or 1.5 GB with unbuffered memory. The Socket 423 interface used on this board provides a Front Side Bus with a maximum operating speed of 400 MHz. The VIA Apollo P4X266 VT8233 chipset controls this board. The North Bridge chipset of this board uses the VIA VT8753 processor, and the South Bridge uses the VIA VT8233 chipset.
Multimedia
The multimedia capabilities of the P4VXAS includes support for discrete video cards using an 8x Accelerated Graphics Port. An integrated sound controller, using the AC 97 2.2 Audio Codec, supports audio applications. The on-board sound controller supports 18-bit analog-to-digital and digital-to-analog converters and 18-bit stereo output.
Expansion Slots
The P4VXAS provides a large number of expansion slots using outdated standards. These slots include five 32-bit PCI slots, an 8x AGP slot and a communications and networking riser. The CNR slot is an outdated slot used to connect modems and Network Interface Cards (NICs) to the motherboard. Although these slots are capable of accommodating most types of expansion cards, many modern video cards require a PCI Express x16 slot, which is not provided on this board.
Ports
The ports available on the P4VXAS includes a pair of PS/2 ports designed to accommodate a keyboard and mouse. This board also includes support for two serial ports, one parallel port, a combination MIDI and game port, four USB 1.1 ports and and three audio jacks for microphone, line-in and line-out. Although it supports a total of four USB ports, this board only provides two external USB ports on the rear panel. The other two USB ports feature built-in USB headers.
