Alienware Aurora r3 memory problem

[JonTheJew]

I bought an Alienware Aurora r3 with the the i7 2600 and 8GB of ddr3 1333mhz and I put the 4 ram sticks into my old computer and sold it and put my 3 sticks of 4gb 1600mhz into the Alienware and now once I boot it up it shows a black screen but everything seems to be working. I think I know the issue but I'm not sure. If anyone could help me out that would be great! Thanks

Install one RAM and boot. Check with one single RAM for all the three separately, maybe one of the RAM is bad.
