Comparison of all available chipsets with DDR-SDRAM support for AMD Athlon/Duron. Although the VIA KT266 was announced months ago, it is only now that the boards are available in larger quantities.

Special Features Of The VIA KT266: 6-Speed USB

In addition to the combined SDRAM and DDR-SDRAM support, the VIA KT266 chipset offers the following important innovations: Three USB controllers have been integrated, thus allowing six devices (without USB hub) to be operated simultaneously. Two of these ports are located on the board itself, whereas the remaining four connected by cable. Generally speaking, most of the boards we tested have no additional cables for the fifth and sixth USB port. This can be remedied by a cable that is appropriatedly coded, which is available from electronics stores for around 8 dollars.

A View Of The Test Candidates

First, the good news: Although we tested all the boards with the maximum possible memory speed, with the exception of the Aopen AK77 Plus, we experienced none of those major system crashes which have been so typical of other tests.
