Introduction

The KT133A chipset is still probably the most popular chipset for Socket A processors right now. It has now matured well and with its usage of normal SDRAM, it made upgrading of people from older SDRAM systems pretty easy. Those coming from a 440BX133 system can still make use of their old memory and other peripherals when they switched to the KT133A and AMD.

The Iwill KK266 is probably the most preferred KT133A motherboard primarily due to its overclockability. It is the only KT133A board that has consistently been able to achieve bus speeds of 160MHz and above with full stability. Other motherboards would already fail to post even at that bus speed but the KK266 is still able to run them without problems. Another selling point of the KK266 is the availability of the RAID version (KK266-R) which has an AMI ATA100/RAID controller that supports RAID 0/1/0+1. The other selling point of the KK266 is the usage of an onboard hardware sound solution. Instead of using VIA's AC97 codec, the KK266 uses a C-Media 4.1 channel onboard sound which overall provides better quality of sound compared to the usual AC97 onboard sound and this C-Media is a hardware sound solution so it won't slow your system down as much as the onboard sound of VIA.

The KK266 already seemed to have everything that one could ask for so what's the reason for making the KK266plus? Well, the KK266plus is a newer version of the KK266. The main difference of the two motherboards is the usage of a better onboard sound solution on the KK266plus. By default, the KK266plus now uses a C-media CMI8378 MX Sound Chip(with 6 channel and SPDIF). Onboard sound now has been better than ever for the KK266plus. It may not be an SB Live! but the mere fact that Iwill included such a good sound chip in the board says something about the makers themselves. For those who aren't too particular with sound cards, the C-Media sound chip will pretty much do the job without spending so much for a sound card. Quality is definitely good and a lot better than the usual onboard sound. What else is different? Not much anymore except for a very minor change in placement of the power connector of the motherboard and the color of the PCB. Some review sites have been sent review samples of the KK266plus still with the active cooler on the northbridge but the evaluation sample sent to me was already a retail model so it didn't have the active cooler on the northbridge anymore.

Just as the KK266 is a KT133A, the KK266plus is also a KT133A so it has the same features basically.
