Is it the CMSX32GX4M2A3200C22 by any chance? It's been tried over and over again, it doesn't work with the 9510. I'm afraid you'll have to return it and look for something else. Avoid anything compatible with XMP profiles technology. This kit proved to work well with your laptop model: Crucial CT32G4SFD832A
I bought today a  Corsair Vengeance kit 32GB (2x16GB) DDR4 3200MHz CL22, and it does not work on my Dell. After I installed the RAM and I torned on the computer, in the midle of the screen appears DELL and  4 orange lights blinking in the frontside, and the laptop does not boot.  What can I make to do this work or what advice can you give me. Thanks.
