on the MSI page says that unregistered memory at 1066Mhz is only for AM3, what is that unregistered and how do i know what memories are like that...

 

I think you're good, man. According to this page under the specifications your memory is supported:

Almost all memory is unregistered or "unbuffered", servers are pretty much the only common application for registered memory use.
