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
