Are you sure the battery isn't just dead on your DM15?

I ran that same test on mine and got the answer of 1.99 (FIX 2) in 8 seconds, 1.999 (FIX 3) in 61s and 1.9999 (FIX 4) in 478s.

This is on a DM15L (exactly the same electronics and firmware as a DM15) on firmware V24 running at 48MHz. There is no real advantage to running the calculator at 12MHz because, while the drain on the battery may be slower at a lower frequency, it takes longer to get things done anyway so you're no better off energy-wise at the end of the day.
