Congrats, JPM! What HSF are you using? I know my AMD 1100T could hit way higher than I have it now - I can hit 3.8GHz on the stock 1.325 VCore; I briefly did 4.0GHz at 1.35VCore, and I know you can take these puppies up to 1.5+ on the VCore.
However, I'm back at 3.8GHz because I have a $20 Rosewill 90mm HSF, and even with all the HAF 932 fans going, by the time the 2 CUDA cards heat up the air around it, ... it's just too hot for my liking on 24/7 crunching.
I think I need water cooling to really watch this thing shine.
