C15 vs. C16

[JCNiest5]

Would naked eyes notice the different of performance between a CAS 15 vs. CAS 16? I mean, other than using benchmark software to actually gives us the number, would one really notice the performance between the two CAS classes?

Trying to decide between these two:

CAS 16:

CAS 15:

And also, whether speed of 2400 vs. 2666 makes any difference.

Thanks for your inputs!

You're talking a less than 5% difference between CL15 2666 and CL16 2400 in raw benches. Even less for real-world application.

See http://www.anandtech.com/show/8959/...-3200-with-gskill-corsair-adata-and-crucial/4

A bigger difference would come in if you planned to overclock, and for that I recommend looking for kits with Hynix chips.
You can get 3000mhz @ CL13 on many of these at a reasonable daily voltage, and on some Micron-based sticks.

What kits have the Hynix or Micron chips?

With most brands it's a toss-up, and you'll have to bin them based on the serial number. G-skill serials have 3400 for Hynix, 3500 for Samsung and 3300 for Micron IIRC.

To guarantee Hynix you'd have to get something like the Corsair Dominator Platinum, though I have these sticks and they do contain Hynix chips.

2666 @ 1.3v
