So I've been wondering, I have two(2) ripjaws gaming 4gb sticks on my pc running at dual channel. So I have 2 free slots available and they're also dual channel so will it be ok if I put there two(2) kingston hyperx beast 4gb sticks in there? so I would have 2x4gb ripjaws gaming and 2x4gb kingston hyperx beast. will it work or will there be a problem? thanks in advance guys!
