I have HP proliant ml350 g6 (E5620@2.4ghZ) I only have 4 gb of ram. I am thinking to add more ram but the price from hp is too expensive. I am wondering if I can get it from other source. The ram currently installed is HP branded but it was actually made by samsung, so I am kind of sure this can be done, but not sure where I can get the alternative ones and what spec it requires. Please advice.
