Hi,
I'm trying to add to the memory, 2X4 GB of PC4-2133P (Samsung), that came with my XPS 8900. I purchased 1X8 GB of PC4-2133 Samsung memory. In installed it in slot 1 moving the 4 GB stick that was there to slot 3. When I reconnected the computer the Power On button was flashing grouping of blinks (I'm assuming some time of code) so I returned the computer to its original configuration. Must memory sticks be installed in pairs?
