So far, it appears that your T6216 has a socket 939 CPU. You linked to an AM2 CPU. will not work.
Now, as far as the NForce 410 chipset and it's support for higher spec CPU's (dual core 939 chips), I am unsure.
I'll do a bit more searching, but at the very least (if your mobo supports it at all) you'll need a bios upgrade for your system to recognize a 939 X2 CPU.
