CORSAIR Vengeance LPX 16GB (2 x 8GB) 3200 DDR4 3200 (PC4 25600) for $124.99
Cheapest i have seen this for without the need for a rebate. This is the Ram you want if you are building a new AMD RYZEN system. Seems to perform the best amongst the rest of the Corsair memory out there. Samsung memory modules and single sided.
