Came from 32GB DDR4-2400. I realize I could have gotten a 2x16GB kit of 2400MHz ram for around the same price, but I don't need 32GB and I was curious if I'd see any difference. Truth is, I don't. Still fast as hell though, and LEDS :)
Good sturdy Ram stick. I have not really tested much of the performance yet but the quality is much better than any other stick I have used. I feel like I could drop these out of a 3rd story window and they would still work. Corsair also offers tons of customization on these: LED fan cooling unit, LED conversion kit.
Corsair Dominator 3200mhz - 16gb
Just got this on sale for cheaper than what I bought the 2666mhz RGB Vengeance for. The silver on the Dominator memory goes perfectly with this build, so RGB isn't an issue. Just installed last night. Runs right. These things are HEFTY.
