    Vista max ram available for OS? and a stupid move...

    I could probably google this but i won't.

    What is the maximum available amount of ram for the OS?

    i.e. i have 3 gigs installed (2x512 and 2x1G) running in Dual Channel

    My system sees the full 3 gigs.

    Yet certain applications, (sorry i forget where exactly i noticed this) indicate the OS has 2 Gig available. I'd imagine that's 2 gig for Vista itself, yet other applications can address memory higher than 2 gigs.. correct?

    While i'm here:

    I installed Vista Ultimate onto my HDD(s). I installed this (maybe while i was under the influence) onto 2x160 GB striped drives for a partition/drive/volume of C:\ with a size of 298 GB reported by the OS.

    I know what a stupid move. I would like to perhaps True Image the OS and restore it to a smaller striped array. Is this possible? I have read some horror stories on acronis related forums.

    thanks all.

    The hang up is how the kernal handles the ram.
    XP = 1GGB
    Vista 32 bit = 2GB
    Vista 64 bit = 4GB

    Those figures are for optimum performance.

    Processes and Address Spaces here explain it better.

    If that's a fairly new install of Vista, re-do it without the RAID-0. I had a striped array for a year and a half and held my breath every time the computer hiccuped at startup. The marginal extra kick in performance isn't worth the extra worry.
    Thank God we're not getting all of the government we're paying for!
