A friend is buying a new Alienware system and will be sending me their Aurora R6. It currently has 16GB of memory in it and I want to upgrade to 64GB and wondering if I can use this:

CORSAIR 32GB (2 x 16GB) Dominator Platinum DDR4 PC4-21300 2666MHz Desktop Memory Model CMD32GX4M2A2666C15

Any help would be greatly appreciated.
