Refers to the Intel 430 family of Pentium chipsets. The first in family, the 430FX, is called the Triton; the enhanced 430 HX is called Triton 2. The Triton chipset supports the PCI bus and was the first x86 chip to use EDO DRAM. The Triton 2 is one of the fastest Pentium chipsets, with support for multiple CPUs, pipelined burst SRAM cache, memory error checking and correction (ECC), 512 MB of memory, and caching of RAM over 64 MB. The 430VX, a third member of the family, supports USB and uses SDRAM. The VX model is sometimes called Triton-2 or Triton-3.
