Chipset Guide

With Intel's newly found place in the chipset industry they decided to improve on their already outstanding design by creating the long awaited successor to the 430FX chipset. This time around, Intel focused their attention more on high end speed and power rather than simply "getting the job done". It is this attitude that gave the 430HX chipset the leading edge over the rest of the market for quite some time, however motherboard manufacturers were reluctant to charge the outstanding cost of the HX chipset. Some manufacturers decided to cut corners by including a degraded Tag RAM chip which only enables the first 64MB of RAM to be cached instead of the Maximum 512MB.

The Performance of the Triton II is still quite competitive today with most higher end processors and configurations. Unlike the original triton, this successor has the ability to support dual CPUs as well as ECC DRAM and USB. The EDO timings on the HX Chipset are considerably faster than those on the FX chipset which means you can expect a greater overall memory performance with the HX Chipset, especially if using over 64MB of RAM, the cacheable limit of the FX. The HX Chipset also extends CPU compatibility to IBM/Cyrix as well as AMD and Intel which makes it a better competitor even today. Its PIIX3 BMIDE Controller is considerably faster than the PIIX controller found in the FX chipset, however it still doesn't support the UltraDMA specification. The Triton II was also the first chipset to even unofficially support the 83.3MHz bus frequency now very common in most decent motherboards today.

    The good ole' days when you could put multiple vendor CPUs into the same motherboard. So simple...

    This motherboard was on my 1st PC. I was very disappointed when faced with the problem that DIMM and SIMM memory can't work in the same time. I used Pentium 100Mhz CPU on this motherboard :)

    Got an ASUS P2L97 board yesterday and I'm reading through this while DoomII is benchmarking. Good times.
