So I ordered the new FX-8350 last week and I need to order a new motherboard. Looks Like I'm getting the Asrock 990fx extreme9. My question is what is the best memory i can get? Specs show 1600, some people say 1866 with an fx, and claims to OC to 2450mhz. I'm a little confused. :ouch: 

Here is some notes from the memory support list: http://www.asrock.com/mb/AMD/990FX%20Extreme9/?cat=Memo...

Note1: 4PCS= Dual channel, supports 4 modules.
Note2: 2PCS = Tested successfully with 2 modules.
Note3: The O.C. mode is not guaranteed. It depends on whole system configuration and other parameters.
Note4: For system stability, use more efficient memory cooling system to support a full memory load (4 DIMMs) when overclocking.
Note5: The mainboard supports DDR3-2000 MHz DIMMs only when you install a 6-core cpu to the mainboard.
Note6: DDR3 2250/2200/2133 MHz will operate at DDR3 2000 MHz when OC.
***Note7: AMD FX series CPU on this motherboard support up to DDR3 1866 MHz as its standard memory frequency.***
Note8: When overclocking, some AMD CPU models may not support DDR3 1600 MHz or higher frequency DIMMs.
Note9: Due to CPU spec, AMD 100 and 200 series CPUs support up to DDR3 1066 MHz. With ASRock design, this motherboard can support DDR3 1333 MHz

I just want to make sure I order the best I can get atm and at the same time I don't wanna have to ship something back. Any input is appreciated, thanks for your time.


If a amd 970fx can run this memory, shouldn't asrocks flagship be able to use 2133mhz?

The board OC at 2133MHz on up, so anything below it doesn't meet OC qualification on this board. If you wanna OC, you can't be pinching on ram's MHz, and what kind of result you expect to find with a lower MHz? 2133MHZ Sniper Gaming Series 4 x 4gb for $100.

The difference between 1333MHz and 2133MHz is like fast and supersonic.

Best bet is a 2x set of 1866/CL9 -- either 2x4GB for 8GB total or 2x8GB for 16GB total.....some, but very few 8350s can carry 2133 sticks, if you need more than 16GB
