Ok, from the specs in the link you gave on the RAM it says:
Corsair makes overclocking easy. Its Dominator series Triple Channel kits set the standard for enthusiast-oriented memory modules developed for the up-to-the-minute Intel Core i7 processor / Intel X58 Express Chipset. This triple channel 6GB kit is rated to run at 1600MHz and has CL 8-8-8-24 timings for speedy performance. Each kit is 100% hand tested for performance and compatibility.
Now, judging from the screenshot, (the top one), it seems you're already running at the suggested rated speed/settings as stated on top where it says it's running @ 8-8-8-20... Actually, it's running a little tighter (which is good) as opposed to the advertized 8-8-8-24...
There is nothing you need to worry about
I was wondering about that. Thank you for your reply. Selected as best answer.
