Ram Speed (Mhz)

Will work just fine.

It will down clock it by itself if needed.

What is the mobo?

Its an ASUS M4A87TD. Its pretty new, got 4 DIMM sockets on it, USB 3.0 and stuff. And thanks   much appreciated   I'll get that RAM then

Yes, it will work just fine : )

4 x DIMM, Max. 16GB, DDR3 2000(O.C.)/1600/1333/1066 Hz ECC, Non-ECC, Un-buffered Memory

I've got the manual right here where it says that, and I understand it, but just underneath it says this exactly: "Due to the CPU spec., AMD AM3 100 and 200 series CPUs support up to DDR3 1066MHz. With ASUS design, this motherboard can support up to DDR3 1333MHz" Thats what worried me   btw thanks for being so helpful  

sorry, that sounded sarcastic at the end, I did really mean it  

The today mobos are really flexible, compare to 5 yo mobos : 0

: )

awesome, thanks a lot, really helped   now I cant get my RAM upgrade   cheers  

You're welcome!

Remember, RAM is sold at the fastest speed it is guaranteed to work at, not the speed it will actually run when you plug it in. This speed is dictated by the motherboard/cpu combination. Running it over or under this "default" speed can be done manually by the user, on most retail motherboards. You just want to make sure the memory you buy is at least capable of supporting the default speed of your board/cpu combination. So buying 1600mhz memory has you covered, with room for potential overclocking if you want to do that at some point in time.

lol thanks and I got the same GPU and RAM as u
