I remember reading somewhere, that many sticks of pc2700 sticks can't do that speed at cas 2. Add that to the fact that this is a brand that some have claimed to be less than stellar. I wouldn't sugggest thinking this will be your upgrade path to a 266 fsb system if you want to be running at cas 2. Then again, it may do it just fine. It's not guaranteed to be cas 2, so just don't expect that. Being pc3000, it should give you a little bit of headroom for O/C if you choose to, but I wouldn't bet too much on that either. I've read better things about kingmax.
PS, this isn't really a hot deal since no one can actually get in on it. Advice would be better from another forum.
