User Feedback :: Ram accounting

Total Ram is 514700
with toram option, I have 478952 (93%) available
without toram option, I have 478964 (93%). What's going on? I expect to alot more if dsl is not loaded to ram.
I am refering to the readings on the bottom right of the enhance desktop screen, is it accurate at all?

i don't know why this is but i doubt it is anything to worry about.
