Hello. Im building a computer and i just need the ram. My motherboard is a ASUS M5A78L-M LX3.

I already have 4GB here, but it's not compatible [ddr2]

My question is, can i buy a Kingston PC3-12800 1600Mhz 8GB HyperX Fury Blue CL10 DDR3 or Kingston PC3-14900 1866Mhz 8GB HyperX Fury Blue CL10 DDR3 ?

I see that one is 1866Mhz and the other 1600Mhz makes any difference? Thanks
 
Solution
The CPU contains the memory controller.
AMD FX Series CPU on that motherboard supports up to DDR3 1866MHz as its standard memory frequency.
Due to CPU spec., AMD AM3 CPUs on that motherboard support up to DDR3 1333MHz.
