Helo overclocking ddr3!!!!!

I have a M5A99FX PRO R2.0 with a amd FX 8350 @ 4.7 overclocked by the multiplier, 200 x 23.5. After a week of work, it is stable. I have a kingston ddr3 1600 and I want to overclock it to 1866, can I do that if I just select that setting from the ram frecuency or do I have to change another setting? Or is better to leave it a default speed? Thank you!!!

Post some info if you don't mind. Like the CPUz memory and SPD tabs. Not enough info on your particular ram.
