No BSEL mod in mine and no mods on the board.
I had a E6400 before and I feel like it's a good upgrade, 3dmarks fly with E7200 and the 3870X2 loves the high clock.
My chip is handling good the Vcore, not to much heat given the cooling that I used (Scythe Ninja) and the ambient around 27°C, I think it can go further without any harm.
