8gb more suddenly = fun

I managed to have this 8GB RAM module for approximately 66th, the last coupon on amazon for this model now replaced by FURY currently sold 69/71, slightly more expensive. But still, 66th to 8GB of RAM I would dù take 2 or 3 at once: / The FURY appears to be at least as good, but I'm not sure, I read various articles that say it is a tad less but it will not feel that Kingston had made some compromises to keep taking down .. In short the cheapest FURY is that which is currently to 1866, the 1600 is more expensive on Amazon. If someone just confirm for me that I can ride in the middle of 1866 on my 1600 config '3570K + GA-Z77-D3H that suit me. The 1833 to 1600 should turn right?
