Sorry its probably been posted loads but I cant find the exact question. Ive been offered 4gb-2x2 of crucial ram for £30, its 2008 spec 800mhz. I just wondered would it work ok in my first generation MP?, and if so would it be ok mixed with the original 667mhz ram? Ive read conflicting views where some say its compatible but will only run at 667 which is fine but then ive also read that it has to be 100% correct. Thanks.
