The VIA KT133 does not support ECC and can support only 3 DIMMs for 1.5 GB of memory. The KX133 did support ECC and up to 4 DIMMS for 2 GB of memory. At least VIA did not continue with the lack of ECC support. The KT266 will support it and up to 4 GB. Of course PC DDR200/266 SDRAM (aka PC1600/2100) is a bit pricy. However the chipset can use PC133 SDRAM. Dependent on the MB of course. As for ECC, using it (or not) doesn't "cause" problems. It can detect and correct them and is highly recommended for servers, especially when filling memory to capacity. The same for using registered memory, which is required with many chipsets/boards when using more than 2 DIMMs. The price difference is small for the peace of mind should there be a problem with the memory. Ask anyone that has had to track down a memory problem or wonder why they cannot add a 3rd or 4th module when they didn't use registered memory. Of course with an Athlon system using the KT133 chipset you would be best served by using high quality memory, such as Micron. More so since ECC is not an option.
