Memory Selection for M5A97

I've l've always asked myself how i should select memory for a specific motherboard.  Let's say for example, an Asus M5A97 with an AMD FX-8350 8 core 4 Ghz AM3+ CPU.

I've got the QVL, but i can't find any of them on the website i'm looking, except those at really high frequency which are really expensive.

If i follow the motherboard specs at TD, it says that it support DDR3 1066/1333/1600/1866/2133 Mhz.  

So does that mean that mean that it support any PC3-8500, PC3-10600, PC3-12800, PC3-17000, or it would be a gross error?

Thanks for the information

Short answer:  Yes

Long answer:  Best to keep to the same spec on all chips.  And same brand.  If you have a mixture of chips the board will run at the lowest speed.  Higher rate chips won't necessarily mean the board will run faster though slow chips will slow the board down.  Boards can't necessarily use the faster chips to their best.  Fast chips cost a lot more as well.

Ok... so if i buy a memory kit of 2x4GB, as long as i stick to these speeds, i should be ok.

I often see "CL11", "CL10", does it mather?  I guess it has something to do with the timings

Yes.  Unimportant unless you are trying for performance and the such.
