The only explanation is that BF3 currently has a memory leak on certain configs. That thread I linked to a few posts above has Balla's screenshots. Evidence points towards a memory leak.
I've got 6 gb of ram, and maxed out (without AA), I eventually run into FPS dips and violent spikes. To see if it would make any difference, I lowered everything to medium; I had 400 MB free. I've got virtually nothing running in the background, aside from essentials. I doubt medium settings should eat up almost all of my 5 gb free.. seems like a memory leak. If I play on Ultra, I constantly have no free memory.
