I've posted this a few times. I'm not trying to sound like some Crucial sales person. I just like to help fellow ATers get the best bang for the buck. You can buy the Crucial cas3 memory and run it at cas2 (2-2-2). I have in my CUSL2, (2) 128 meg cas3 sticks and (1) 256 meg cas3 stick. I'm running perfectly at 133 FSB with my settings @ 2-2-2. Yes, thats 512 meg of ram. Overkill, but buy it while it's cheap! Anyway, 128 meg cas3 goes for $60 and the 256 cas3 goes for $128.
