Hi PaQ,

> On xp64, with 8 gig's, MoI stop meshing when reaching 3.3 ~ 3.4 mega

Yeah that is not unusual because the full address space to a program is not completely empty, other stuff such as the program code itself is in that same area.

Also the available address space can get diced up into sort of "fragments" where there isn't a big single block of address space available for something that needs a big single chunk.

Similarly if you have it at the default 32-bit 2Gb/2Gb split you will tend to actually max out more around 1.6 Gb of actual use.
