I have an Aurora R12 and was wanting to remove the two 4GB 2Rx8 PC3 RAM sticks from my old Alienware X51 R2 and put them in my Aurora. First, are these RAM sticks compatible with my Aurora. Second, do you know of any videos that can simplify the process for me? I had done it once before to my Aurora years ago, added more RAM with no issue but don't remember the entire process. 

My PC specs: 
Processor 11th Gen Intel(R) Core(TM) i7-11700F @ 2.50GHz (2.50 GHz)
Installed RAM 16.0 GB (15.7 GB usable) -16GB, 2x8GB, DDR4, 3200MHz, XMP

1TB 7200RPM SATA 6Gb/s
System type 64-bit operating system, x64-based processor

Thanks!!!
