}}The '''Intel 430HX''' (codenamed '''Triton II''') is a chipset from [[Intel]], supporting [[Socket 7]] processors, including the [[Pentium (original)|Pentium]] and Pentium MMX. It is also known as '''i430HX''' and it was released in February 1996. The official part number is 82430HX.

==Features==
The 430HX chipset had all the features of the '''430FX''' (Triton I) plus support for [[error correcting code|ECC]], parity [[Random Access Memory|RAM]], two-way [[Symmetric multiprocessing|SMP]], [[Universal Serial Bus|USB]], and then current [[PCI Local Bus|PCI]] to improve speed.

It consists of one 82439HX TXC, the [[northbridge (computing)|northbridge]] and one [[PCI IDE ISA Xcelerator|PIIX3]], the [[southbridge (computing)|southbridge]]. The 430HX chipset supported up to 512MB of RAM (64MB or 512MB cacheable depending on tag RAM size).

==Limitations==
Not all 430HX boards allowed for tag RAM expansion, only allowing 64MB cacheable; 430HX also did not support the then-new [[SDRAM]] memory technology. Dual-voltage support, for Pentium MMX or [[AMD K6]] CPUs, was also not mandatory on 430HX boards, requiring the use of an [[interposer]] to step down the voltage.
