I did a Quad Core test on that Mobo and it worked out to only 2 Cores results and test all in another thread, so I really doubt it'll handle 6Cores especially since the socket can't jump 2 generations ahead.
And even if you do end up using a 6Core in it it'll keep jamming and stalling like mad..... it's safer to go for a new board.....
