Difference between actual/reported RAM

When I had 2gb of RAM Windows reported 1.86gb. I just doubled it to 4gb and
it shows in the BIOS as 4gb but in Windows only 2.85gb. I realise that it's
probably being eaten alive by my video and TV-FM cards plus other
parerphernalia but isn't that loss a bit much?
Is there anything I can do to improve matters or should I just ignore it?

Thanks Jim, but that is as clear as mud to me unfortunately.

windows will not recognize 4 gigs of ram and it is also a limit of the
chipset on the board. It is just a limitation. If you want to run and see 4
gig of ram you need a 64 bit OS. I never did find out if it is being used
even if you can't see it. Even with Vista, 2 megs of ram is plenty.

When I removed the extra 2gb the system took forever to boot for some
reason, so now it's back in. A waste I guess but hopefully wont damage
anything.

A 32 bit system will only addrss 3 gig of RAM. You won't see all 32 in Vista because some addresses are used by the video card and for other things (think available unique addresses rather than RAM). The mother board will also limit you based on the chipset.

If you are using dual channel memory you have to make sure that you left the remaining memory boards in the proper slots for dual channel to work (Probably every other slot). I have four gigs installed just for symmetry so that the memory will run dual channel. You don't want an odd number of slots occupied. I still only get to use 2.85 gigs

x64 Vista will allow you to see all your RAM without issue.
