i dunno i agree with bryanl, defective doesnt mean doesnt work flat out just means it doesnt work as it was designed. i have no idea what the ram was designed for but i do know that patriot isnt the best brand =P me personally i would buy ram that is 5% faster for a few bux more sure 5% isnt much but come on now you goign to upgrade other parts anyway not like you are on a 5$ budget and a computer nut.
de·fec·tive/diˈfektiv/Adjective
1. Imperfect or faulty.
imperfect not that it doesnt flat out work.. not trying to argue we all have diff opinions right? or is only one persons opinion right?
