Socket AM3 chips to work in AM2 boards?
With the Athlon 64's integrated memory controller, a move to a new memory technology has traditionally required a new CPU socket. However, AMD will soften the blow with its future switch from Socket AM2 to Socket AM3, according to a report by DailyTech. The site says AMD has revealed that upcoming Socket AM3 processors will support both DDR2 and DDR3 memory, and that they will work in both Socket AM2 and Socket AM3 motherboards. If that's the case, users of current AM2 systems may be able to upgrade to AM3 chips without buying a new board or memory. The opposite won't apply, though, since AM2 chips reportedly won't work in AM3 boards.
A time frame has yet to leak out for the release of the first Socket AM3
parts, but DailyTech believes the introduction could be simultaneous
with the launch of chips based on the so-called "K8L" microarchitecture. Previous reports have indicated those chips may appear in the first half of 2007.
