I have all four 2GB DDR2-1066 rams running at full speed with no problems. I`ve read that AMD Phenom`s at 1066 are limited to one DIMM per channel where as DDR2-800 can be used for both channels.

Interesting to keep in mind for the future. I had not heard that specifically with the phenom 2.I assumed it was just that mobo's had poor memory controlers when i had heard of people not able to run 4 sticks at 1066. Im am glad that it is working for you.

Thanks. AMD Mobo's don't have a memory controller built in because they are integrated inside the CPU. I don't know why AMD doesn't just fix this problem once and for all.

Currently they are now having problems with the newer AM3 CPU's where they can't run full DDR3-1333 with all four DIMMs used on a mobo, so they will be stuck with DDR3-1066. Once more AMD needs to fix this problem. Currently Intel does not have a problem with the Core i7 Integrated memory controller.

i7 has memory controller built into the cpu as well, except its triple channel and runs ddr3 2000+

Though AMD is coming out with their quad channel memory controllers sooner or later.

Yes, AND's DDR3 CPU's can also run all four DIMMs past 2000+. But I think they are rated for DDR3-1333. Anything can be HyperClocked8)

i thought their was a bug that cause the memory controller on AM3s to run DDR3 in single channel mode??? of course i never finished reading that article on anandtech but can some one please fill me in
