Intel 450NX

The Intel 450NX is targeted at server and workstation applications and allows for Quad Xeon processor combinations in 4-way SHV (Standard High Volume) server combinations. Unlike the two component 440GX and 440BX solutions, the 450NX consists of four components: 82451NX Memory and I/O Bridge Controller, 82454NX PCI Expander Bridge, 82452NX RAS/CAS Generator and the 82453NX Data Path Multiplexor. Since deployment of this chipset is in mission critical server and workstation applications, so as to ensure reliability, the 450NX performs data checking at 3 main junctures of data transfer. This chipset however, is not very suitable for graphics intensive applications due to the lack of AGP support.


The Key Features:

  • 100MHz CPU/memory bus
  • 66/75/83/95/100MHz FSB capabilities
  • Up to 8GB main memory supported
  • Quad processors supported (SMP)
  • UDMA/33 protocol supported



    Types Of Memory Supported:

  • PC100 SDRAM
  • Extended Data Output (EDO)
  • Fast Page (FP)

    Note: Although the 440LX does not officially support the 83MHz FSB frequency, most motherboard manufacturers have successfully released boards that are able to run at this speed (overclocked).
