True, but faster ram = bigger bandwith. FX and APU likes bandwith, which means faster speed.

Faster Ram= bigger bandwith
Lower Ram Timing = faster speeds within the bandwith

So am I okay for the time being with 4GB of 1866mhz? Later on in a couple of months I will buy more.

I would never go back to a 4GB rig... even my 3 year laptop came with 6GB of ram, and its a mid range dual core machine. I Watch ram ussage on my keyboards screen (g15) and i see even on my laptop i use almost the full 6GB all the time running games, or many tabs of crhome.

My desktop has 16Gb, and ive seen it go up to 12 GB doing normal stuff. Ive noticed the more ram you use, the more your applications will use. The applications on my laptop that use 2gb, now use 4-6 on my desktop.

Something to keep in mind....The GPU of the APU uses system ram. So the more ram you got the better. And yes ALL AMD chips prefer a tad faster ram, from what I've read most report 1866 to be the sweet spot.

1866 is the sweet spot for FX chip not APUs. 2133+ will be better overall.

I just made a FX 8350 build a few weeks ago, would I notice a definite increase in performance going from 1600 ram to 1866?
