Hi all !!!. Im having a hard time getting a new pair of Gskill Ripjaws4 2400mhz 2x8gb so i can have 32gb in my PC of the same type..... It seems that all the vendors here are only offering the Ripjaws V, and i dont know if my PC will work with differents memories. My idea is to get the Ripjaws V with almost the same specs of the Ripjaws 4 that i already have. Sorry about my english and thanks all for reading me.
