AM3 CPU in AM2 Mobo

[DorianGraves]

I think this is the right section.. Ok, so here's the situation. I'm looking to upgrade my prebuilt computer. I got it a few years back, so it has an AM2 mobo with a 65 watt TDP max. I have found a 65w AMD Phenom x2 905e, but it has an am3 socket. I know that an am3 CPU will physically fit into an Am2 socket, but will it work? Thanks in Advance for any help.

Hi, The new CPU will probably require a newer BIOS version and the prebuilt systems will not allow you to do it. What's the PC model?

I don't know the model, but I know the specs, if that helps? It has an iris8 mobo, if that also helps..
