I know Dell doesn't want to hear this, but their price for memory is pretty steep.

On a new XPS 8960 desktop, Dell wants $450 for 64GB memory (vs 16GB). But I can buy compatible major-brand, high-quality memory (2 x 32 GB) elsewhere for $170.

Can I order the XPS from Dell with 16GB, discard the 16GB memory module and install my 3rd party 64 GB? Any issues other than insuring a compatible memory module?

BTW, the compatible memory is carefully speced to match Dell. Plus a reviewer at the memory vendor confirms that it works with the XPS 8960. My only concern is an unforseen issue with removing ALL the Dell memory from the get-go. Well, maybe I will boot up once with 16GB to confirm it's operational, and then replace the 16GB with my 2 x 32GB.
