Hey guys, just recently bought this computer and slapped a GTX 580 and new power supply into it, but want to add some more RAM. Stock, it has only 8GB for the Sandy Bridge i7 2600. I want to get 16GB in there (4x4GB). Was wondering if anyone who knows could tell me what type of RAM it has (240 pin, 184 pin, etc.) it would be a huge help! Thanks Fellas! And ladies!
