It's only 1066 with a supported CPU, I still haven't found a list of supported 1066 CPU's
The CPU support list on the Gigabyte site doesn't specify which ones are 1066 supported
and which are DDR2800 supported I suspect the Phonems are 1066 but I'm not sure it's been awhile since I played with AMD. Before you order I would want a little more conformation that the DDR2 1066 will work
