Hi, John.

I assume you are running 32-bit Win7, but you should always tell us
specifically what you are using when you post a question, especially about a
memory issue like this.

How have you determined how much memory is being used?

Because some of the 4 GB memory addresses must be reserved for hardware and
other overhead, 32-bit Windows cannot use the full 4 GB (even if 8 GB is
installed); typically, about 3.1 GB is available - as you apparently already
know. For us to even guess what might be using more of your computer's
address space, we would need to know more about your computer's hardware
configuration - and maybe about device drivers and other features of your
specific machine.

I am having trouble with Win7 managing memory. It uses less than 2GB of
the 4GB I have--and the system knows it has that much--so that the CPU
just thrashes, apparently trying to run in insufficient memory. Under
Vista, memory would normally run around 3GB nearly all the time and the
CPU would effortlessly do its stuff.

Anyone else have any memory issues?
