    RAM not usable


    I have 8GB installed on Win 7 Professional 64 bit. For some reason Control Panel reports that 4GB are recognized but unusable (screenshot attached). Any ideas what I can do to get that 4GB back?

    Hello there.

    Do you have the "Memory remap" option enabled on the BIOS? if not, please enable it. if you can't find it inside the BIOS. then boot into Windows, type "msconfig" without the quotes on the search bar, run as administrator, go to the boot tab, click on advanced settings and uncheck "Maximum Memory". (the top right option)

    Reboot and check.

    Post back your results

    Memory remap was already enabled in BIOS. Just for grins I disabled it and that of course made it worse, so I reenabled it.

    msconfig already has no check for Maximum Memory.

    Do you have onboard video or a video card ? Is your memory all the same make & model & speed ?

It's funny, because ALL of my RAM was usable some time ago. (I have no idea how long ago this was, but it was on the same OS) I am using Windows 7 Professional 32-bit. I know about the whole 32-bit issue where some say you can't use much more than 3GB. Well, I WAS. I wouldn't be writing this...

What's this all about? Last time I checked system properties it said 5.5 GB usable. Now, today I noticed that my sidebar said that my memory is 40% in use and there's only 1.5 GB available. What's going on here? I was thinking it could be my video card taking the memory, but I didn't change any...
