Corsair 16GB DDR4 Red Vengeance LPX 2666MHz vs LPX 3000MHz

Hello,

So I've decided on buying one of the following two RAM kits:

https://www.scan.co.uk/products/16gb-(2x8gb)-corsair-ddr4-vengeance-lpx-red-pc4-21300-(2666)-non-ecc-unbuffered-cas-16-18-18-35-xmp-

https://www.scan.co.uk/products/16gb-(2x8gb)-corsair-ddr4-vengeance-lpx-black-pc4-24000-(3000)-non-ecc-unbuffered-cas-15-17-17-35-xm

However I'm terribly confused. The latter one has a higher frequency (3000MHz) compared to the former (2666MHz), yet also has lower CAS latency (15-17-17-35 vs 16-18-18-35).

What's more odd is the latter is about 50p cheaper! So what am I missing here? Granted the latter takes more voltage, but I'm making a new build with an Asus Maixmus VIII Hero and an i7 6700K, so I wouldn't think that would cause more of an issue.

With all this info surely one would be silly to get the former one over the latter, no?

Thanks in advance.

Jamie

  1. Best answer
    the upper was the first DDR4 stick Corsair released hence the bad latency
    go with the latter

  2. What CPU and mobo? The 3000 is the the better set by far. You'll prob want a K model CPU and it may require a bit of a CPU OC to run at full 3000

  3. Thanks for the replies.

    Intel i7 6700k and an Asus Maixmus VIII Hero. Think going to go with the 3000 one then :)
