8GB RAM, but only 1024MB used by S2?

Happy New Year ~ ALL ya'll!
I'm not sure this is a "Graphic card" issue, but I'm gonna post it here anyway...

I'd really like my game to play with more than 2.86GB of CC *sigh*
My config log (attached) says I've got 1024MB memory; but - I've actually got 8 GB on my machine (see picture #2)
How do I get my game to use all of it? (I've already used the chili-pepper thing to set it to >2 GB ~ see picture #1)

Thank you! *cheers*
