What's the better memory for my rig?

ASRock 990fx Extreme3 + AMD FX-6300
Thanks.

Any of these G.Skill series RAMs would do the job:

For that, get some DDR3-1866CL9 (or 8 if available).

You might be able to overclock it even faster, but typically 1866 is where most of the FX CPUs can operate 2x4GB or 2x8GB kit.

Will I have problems with Corsair Vengeance CML8GX3M2A1866C9B 8GB (2X4GB)? The cheapest option I have without ship taxes.

That's a good choice.

I'd look at the GSKill Snipers in 1600?9, can try the 1866 sticks, not all 6300s can carry 1866 so be prepared to drop to 1600 and tighten timings just in case (or doing a OC to the CPU which can help hitting 1866
