You want the Samsung ram. ...Or elpida? (SP) is good too. to find out the type of ram that is with the cards there is a number you have to ask to tell you if it matches it. To get that number, you'll need to google how to find out which ram is in whatever card you're talking about, and chances are someones done a write up on it. it's how I planned on getting a slew of cards from China. I have been researching much about which card to get ; what I have not found is a good bulk gpu reseller, unfortunately. I need to find one, as I'm in the market for 50-100 video cards. (and, I still have money set aside for the 28-34 deal we discussed, this part of the message is directed to a pair of eyes that may or may not be reading this thread).
