Sorry, it won't work because the pin setup is different between AM2 and AM3.

Whatever you do, don't try and jam that AM2 CPU in there because you'll risk damaging the pins on the perfectly good AM2 CPU and also the pins can get jammed and stuck into the AM3 socket of that motherboard.

Nope, it won't. am2 cpu's have only ddr2 memory controllers, the am3 socket boards use ddr3.

Don't think it will work as AM3 motherboards use DDR3 RAM and the memory controller is built into the CPU and AM2 CPU's only have DDR2 controllers while AM3 CPU's have both.
How did the 955 die anyway?

It will fit but won't work due to the DDR3, they use the same pin layout as AM2+ mobo's will run both AM2 and AM3 CPU's which would make one instantly assume AM3 doesn't have a different pin layout (or such things shouldn't work). No? I do however agree on the DDR3.

[edit]NVM I found the answer... The AM3 CPU has 938 pins which is 2 less than the AM2+ oh well. I guess I never really bothered to do much on AM2, back then I still had my old Newcastle core (?) AMD64 original single core lolz. I did a huge jump.

Yea not gonna fit. An AM3 cpu will fit on an AM2 mobo but an AM2 cpu will not fit on an AM3 mobo due to and extra pin.
