There may be VIA compatability issues as noted on several "tech sites", however, I would have to agree with KDOG that I am on a KT133A mobo with a SB Live! and have also never experienced any issues. It's been incredibly stable. I think if we all drove Ford vehicles we'd have a lot of people having trouble with Ford if you know what I mean. We all (or most) use VIA chipsets, therefore, if we experience problems with anything, we can blame it for all of them. Being in computers for as long as I have, I've learned there are a lot of variables and configurations that can cause problems, regardless of what chipset you use. Don't tell me that SIS is total perfection, cause I've seen a lot of threads starting like this "Trouble with ECS K7S5A..." or something to that effect. You know another thing we almost all have is Windows...hmmm.
