Memory Support:

Side port of 16bits it can use up to 256MB of system RAM for the IGP

DDR2 1066MHz, impressive becouse JEDEC wont release a standard and AMD normally follows JEDEC, will be interesting to see real support of DDR2 1066.

DDR3 1333MHz, this might be a new thing AMD CPUs might already have integrated DDR3 capabilities into their IMC
