First, what success have you guys had running 4g of ram under Win XP x32? Most of the threads I read about it say 'Win only recognizes 3.25g' or 'Win recognizes it all, but 0.75 is reserved for kernel use' or some crap.

I would like to put 4g on my new system instead of 2, but obviously if I won't get the extra performance then what's the point?

Secondly, if it does indeed run 4g, have any of you guys had any luck finding a good set of 2x2g dual channel 800Mhz DDR2 sticks? The only ones I can find are from G.Skill, Giel, or Kingston. Not a lot of options.
