fx 8320 3 ram sticks 1866

[Executor77]

Is there any risk of oc 1600 1.5v ram to 1866 1.65 when using 2 x 2 gb + 4 gb ram sticks running fx 8320 @ 4.5?
Heard fx is limited to 1600 with such amount of sticks. What does it mean?

Actually FX supports up to 1866 MHz (officially) and some AM3+ boards support up to 2133 MHz of overclocked memory. What I know is that you can't over clock with an odd number of memory modules, you should have a matching pair of every memory module operating in dual channel mode to be able to over clock. Also I read somewhere that AMD platforms gain better memory performance from tight timing than from higher frequency clock.

i have managed to set 1866 10-11-11-36 but read if ram speed isn't rated it could damage MIC or cpu. Everything worked and had better results in aida64 but after reading about it i set it back to 1600

The FX-8320 officially supports 1866 MHz RAM so I doubt that it would be damaged. You can try to lower the latency at 1600 MHz and see if it improves your performance. I know that sounds like kind of a waste, but if you can get a matching stick of 4 GB ram, remove the 2x2GB ram modules and operate 2x4 GB RAM sticks instead, I think you would be able to get better overclocks. The reason why I said take the 2x2 RAM sticks out is because systems which have all memory slots occupied usually don't overclock well.

yea i think i will look for another 1600 4gb stick and sell 2x2. Thx for answer.
