Maybe, it may take some work (and voltage) though, the P965's were not the best ram overclocking boards - mione topped out around 640 MHz with pretty scary vMCH and around 1200 with safe voltages.

You'd be better off going for something like the Gigabyte UD3P or UD3R (they are cheap and clock ram extremely well) or an X48 like the DFI T2RSB Plus or Asus Rampage Formula.
