Ok, i bought 256mb pc133 of micron memory around april of 99. Im not sure at all what CAS rating it is. I want to upgrade (cause nows the time) with another stick of 256mb pc133 crucial CAS 2. I want to know if my micron ram can run at CAS 2 so my latency will keep down. Also could someone help me with the bios settings to implement this on a ASUS K7V??
