|AMD main chipsets are much more accommodating that Intel ones regarding backward compatibilty - whether you can install older cpus.|
This is an AM2 cpu
but it can be installed in AM2+ mboards. It can be installed in many AM2 (940 pin) or newer mboards that use DDR2 ram.The cpu supports up to and inc. PC2-6400 ram
However, there were a few early AM2+ models that CANNOT support 125watt cpus because of inadequate circuit traces and / or inadequate voltage regulator amperage capacity (which was stupid because many AM2 mboards do support 125 watt cpus). The AM2+ retail mboards that DO support 125 watt cpus often have obvious mentions of them supporting at least that if not up to 140 watt cpus.
Or - simply look at the cpu support lists for the model
I have installed one of these (and a 6400+), in an Asus M2N-E SLI, then an Epox AM2 mboard, and now in an Asus M3A78 Pro mboard (AM2+), and it works fine.

in any brand of mboard that has AM2+ listings.
