Hey everyone. I'm looking into chips and specs for a friend, and we've pretty much settled on a the Thuban based Hexa core. The issue is that this friend as a (relatively speaking) old AM2 motherboard with an Athlon 1 X2 in place. I've heard conflicting reports about whether or not these two pieces of hardware are compatible. Can anyone confirm if an AM2 motherboard will indeed support the Thuban hexacore, and if this is the case, what bottlenecks would most effect the new processor from reaching it's maximum potential.

...Really?

I thought it was a "one size fits all" type of situation, where as a general rule, AM2 boards supported AM3 chips. I keep hearing conflicting reports. :/

am2+ and am3 have more or less complete backward compatibility, when you go back down to am2, it might (probably not) considering chipsets and bios updates. it depends on the make and model of the mobo.

Oh it's true that AM3 cpus can work on AM2 and AM2+ motherboards.

Just the issue of the Motherboard makers giving out a bios for these cpu's to work on them. Some Motherboards have the bios to do so and others dont.

Then there some that can support some of the AM3 cpus while it cant uses other AM3. (most of the time its a the wattage issues (some motherboards can only hold 95w cpus) but there are some motherboards that can handle the cpu wattage (125 to 140) but they dont support the new cpu's.

So who knows. Maybe it can handle it. maybe it cant. As zip said, you'll have to look at the CPU support list for your motherboard to know.
