Are you using the Evga Precision X software to do the overclock?

Did you link the cards so that all three have the same settings? Did you save the settings as a profile?

If you run the cards at stock are they working as they should? Are you getting high fps and in games are they also getting high fps.

Can you run 3dmark 11 and post a score? Not very familiar with heaven benchmark.

I come close to that score with 2 cards (my cards overclocked to 1179 Mhz GPU, mem 1762 Mhz I think, Precision does not seem to report it correctly.)
