System Stability!

[Argyris84]

Hello, i am new in the forum and i would like to ask if using my motherboards optimal performance it is ok.

I have Asus Sabertooth 990fx , the corsair Vengeance memory CMZ8GX3M2A1866C9B and Amd fx-8150.

I used bios optimal performance and the cpu go from 3,6Ghz to 3,9Ghz (with the stock cooler) and memory at 1439 Mhz from 1333Mhz (normal Performance).Is this ok?
Can i push the memory at 1600Mhz with the cpu at 3,9Ghz and how can i aggive 1866Mhz to the memory speed.Thanks

I am sorry I cant tell you how to over clock but what I can tell you is not to go over 2.0 Volts on the memory voltage. I would check some of the over clocking sites on how you over clock that MB and CPU.
