The Paladin :
the board number you types does not come up anywhere but if you meant your board is Gigabyte GA-G41MT-S2 (rev 1.3)
then look at this page it shows all compatible AMD CPU, Q9650 - AT80569PJ080N / BX80569Q9650 / BXC80569Q9650 being to one.

Sorry, but you are very very wrong here.
That's a socket 775 Intel board, Always go back to the website of the manufacturer.
