Only after VIA made headlines after introducing their KT266A, they are back again in the lime light with the new KT333 chipset. After the unprecedented success of the KT266A chip, we can sure expect to see something even more with the new KT333 chip. This is the first VIA chipset to support DDR333 memory, which is said to give a performance boost of around 25% from DDR 266. The KT333 offers a number of other key features such as AGP4X, ATA-133, integrated six channel advanced audio, six USB ports, integrated 10/100Mbps Ethernet and a few more other cool stuff. SOYO didn't release their KT333 solution as soon as it was released by VIA. Instead they delayed their release until they were able to offer a board which had all the goodies the KT333 chipset could possibly offer. The SOYO dragon line series are turning to become one of the most sort after boards in the motherboard arena and today we bring to you their latest addition The KT333 Dragon Ultra.

Block Diagram of the KT333 Chipset


We did not come across any issues while installing the board at all. Following up on the tradition of the dragon series, SOYO has once more included a very detailed manual to sort things out if you're having trouble. Remember that this board comes with the "Fan Off Control" system as well, so make sure you attach your CPU cooling fan to the appropriate fan header. Other than that there were no issues at all, so I would assume none of you would have any problem either.
