Adding extra RAM to Dell XPS 420 Tags: Memory Dell Studio Xps RAM Kingston Last response: December 1, 2012 8:16 AM in Memory Share Makaz November 30, 2012 5:54:28 PM So I recently went from win 7 home premium 32bit to 64bit as I upgraded my RAM from 3 to 6GB. I have now a total of 4x 2GB Kingston DDR2 667Mhz PC2-5300 240-pin DIMM which I am trying to use in order to reach the [8GB maximum] ram my motherboard [Dell 0TP406] supports. However when I swap out the 2x 1GB DDR2 667Mhz PC2-5300 240-pin DIMM that are in there at the moment, for another 2 Kingston sticks, the PC won't boot (not even load BIOS). I have swapped combinations of the Kingston sticks between themselves, so there is no hardware fault with motherboard or RAM sticks. I also tried 3x 2GB and 1x 1GB sticks, BIOS loaded then Blue Screen Of Death appeared as Windows began to boot. ANY help would be amazing!
