Hello, I have bought an empty case and assembled parts of Clevo P775DM1. Basically the laptop had no display or MXM Gpu or CPU. For test case I had a CPU lying around G3900 and put it in. I also have mxm gtx 965m Clevo card. I also have installed screen from alienware laptop 2k resolution 120hz. Now the problem. I have 2x8GB rams 2133. single channel works without a problem, but when I try to use both of them the laptop does not boot at all. Won't start fans just blue led keyboard lights up. in single channel both rams work with no problem. And I've tried both slots, since the laptop has 4 slots. Still not working. If you can help with any of the problems, it will be much appreciated.
