So, here's the deal. I recently bought a new XPS 8900. I have switched out the 1TB HDD for a 500GB SSD.
Now I want to increase the RAM. It came with 8gb (2 x 4gb sticks). To be absolutely sure I got compatible sticks-I bought 2 x 8gb sticks from Dell. My machine has 4 slots, so I can have 4 sticks...
My Question is: can I use all 4 sticks ( 2 x 4gb and 2 x 8 gb ), or will mixing sizes screw up something?
Thanks, for any advice!

Yes Make sure to keep the matching sticks paired in matching slots. or in other words, put the two 4GB sticks in the white slots and the two 8GB sticks in the black slots. ( or vice versa).
You might consider running the built-in memory diagnostics after installing the memory.
