DRAM oc help :/ !!!

[Habby]

Hey guys!!! the title says it all, I have these G.skill ares advertise to run at 1600mhz cl7, when I used z-cpu to check the numbers something did not fit ( like cl and frecuency), so I though I shoud oc them so I could squeeze some better performance put of them. So I checked  the stickers in the DRAM sticks pointing they I could  run these timings 9-11-10-28 at 1.65 volts, then I went to the bios and changed the timings myself and also "boosted" the frecuency up to 2133mhz at the time I just thought..  why not? but then when I wanted to see the benchmarks, the bios menu says the DRAM speed is running at 1833mhz   and z-cpu displays something completely different (or so I think, I actually need some help to understand what all these timings do). So I was thinking, could you help me out figuring out the best oc setting to get the maximum performance I could possibly have out of my ram???. I am leaving  some images of what I explained earlier, btw I am really a newbie with all these overclocking stuff so please don't mock me <3 .
