Anyone who knows a bit about overclocking will know that a triple channel kit is harder to push than a dual channel one, while a high-density kit ups the ante even more. So it was to be expected that the Corsair Vengeance triple-channel kit does not overclock to extremes at normal latency. While this can be excused, a somewhat bigger downside may the fact, that the kit did not manage to boot at 1333 MHz CL6. This may be a dealbreaker for some who do not want to overclock their system but aim for the lowest latency possible.

On the other hand, the Corsair Vengeance did manage to overclock well over 10% using the intended settings, which does translate into better overall performance of the system and you can choose to run the three modules at CL8 instead of 9 without having to sacrifice any overall speed.
Users who mostly play it safe, but still want some performance boost out of the system will get a feeling of having invested the money wisely. That said, if you want to push the system as far as it can go, you may want to consider a lower capacity kit from Corsair - but all of those wanting loads and loads of memory along with a healthy dose of overclockability, without having to push the voltage past JEDEC standards, the Corsair Vengeance may just be a great choice.
