Safe is always good :up:
I think your results are where they are suppose to be, but Im pretty sure I can help you out a little to break the 12k barrier :up:
1) Download the lastest version from everest from
Here
2) tRC at 45, with such a nice pair, Im pretty sure you should be able to lower this and this will bring a huge improvement so try lowering this in small steps to test and see. (Mines is at 30, but I have 2Gbs and 1600Mhz, just a reference)
3) Read the Anandtech review (google "mucho bang mucho buck") and go to the Memory Timing section Part 2 (advanced timings). There are some that must be left at auto and some that must be changed.

I messed with my Advanced Timings and I didnt have to change voltages of anything so Im pretty sure that will make you brake the 12k barrier for sure :up:
Remember tRC is the most important one in the advanced settings.
Good Luck
