MSI send over a list of their motherboards that support AMD's upcoming 45nm AM2+ processors and 45nm AM3 processors. The new 45nm AM2+ "Deneb" chips support only DDR2 and will be released later this quarter while 45nm AM3 processors with DDR2 and DDR3 support will be rolled out in 2009.
The AM3 45nm CPU's can be used in new socket AM3 based MSI mainboards (ETA 2009) in combination with DDR3 memory. Besides this the AM3 45nm CPU's are pin-to-pin compatible with the current AM2+ mainboards, but limited to DDR2 only. There are more than 20 different AM2+ mainboards from MSI and counting. The list also includes the award winning "DKA790GX Platinum" and "DKA790GX" which are the first AMD mainboards equiped with DrMOS for efficient and cool performance.
The official threshold of new 45nm process processor technology, which will make the current Phenom™ processor to break the 2.6GHz maximum clock, and then raise to 3.0GHz. As for the processor TDP, it will reduce to from 140W to 125W. Support DDR3 memory is the most important feature of the AM3 CPU. It is a major upgrade for users looking for high-performance platform.
In order to serve the users well, before the 45nm Phenom™ processor sale in the market, MSI provides an easy upgrade concept. The upgradeable BIOS allow the previous Socket AM2+ mainboard to support the AM3 and AM2+ 45nm processors. At present, a number of products have completed the pre-verification procedures, and enables consumers to download the BIOS, including the AMD 7 series and NVIDIA® series chipset based products. Users will enjoy the fun of upgrading to new nanometer process processor.
Here's the list, it includes links to the BIOS version necessary to support AMD's upcoming processors:
