Hi, I'm buying a Alienware Aurora R10 with 16GB Dual Channel HyperX™ FURY DDR4 XMP at 3200MHz; I'd like to do one of the following: 1) buy an additional 16GB from other brand (DDR4 and 3200MHz). Would there be any compatibility problem? Do the two 16gb memories need to be the exactly the same or as long it's DDR4 and 3200mhz any other memory will do? 2) Replace it with G.Skill Trident Z Neo 32GB DDR4-3600MHz. Would there be any issue in using this with the R10 since it's 3600MHz? Dell only sells RAM up to 3400mhz. Thank you for your help
