These are two G.Skill RipJaws 4 DDR4 RAM kits. Both of the kits are Quad Channel 16GB (4x4GB) at 2666Mhz XMP. Compatible with Intel and AMD HEDT platforms. They were used in my gaming PC together to make 32GB (8x4GB) of RAM in total. I upgraded my PC recently, so I'm selling these two kits together. The price is both of them, no individual sale.
