I'm running Windows Vista Home Premium (SP2), with 2 GB of RAM, Firefox, CA
Security Suite, MBAB, SuperAntiSpyware Professional, Cleaner and Spybot
search and destroy on an Acer Aspire T180 desktop. All WU's are current and
the machine is working just great.
About 6 months ago I noticed a reduction in the amount of usable installed
memory. I have 2048 MB of installed RAM in 3 slots (512 MB, 512 MB and 1024
MB-with one slot empty), but only 1792 MB of usable memory. The usable
installed/unusable installed difference is 256 MB. The difference may mean
that some of it has gone bad or whatever.
Is there anyway to ascertain why I'm not able to take advantage of the full
2024 MB of RAM? Is it possible one of the memory sticks is not plugged in
correctly or there's a dirty contact somewhere?
I realize that this may be a `don't fix it if it ain't broken' situation
since the computer runs just fine but if there's something I can actually do
to get back the missing 256 MB of RAM that'd be nice.

Hi,

Could simply be ram used/shared by video if your system is set that way.
256MB is a common amount.

What does the system BIOS report as being installed?

Is it possible that the graphics chip in the system is using 256MB of shared
memory.?
How much memory does the BIOS say your system has?

Rick, I'm not sure how to check the BIOS report. Perhaps you could guide me.
When I used `Belarc Advisor' it reported that there was 2048 MB installed.
Not sure if Belarc gets it's information from the BIOS. PaulC.
