I recently upgraded from 6GB RAM to 24, the maximum my MoBo will support. When I check in Windows 7 (64 bit), it says 24GB ram installed (16GB useable).

I've unchecked maximum memory in msconfig but it still shows that 8 gigs is not useable. I've heard that sometimes hardware can reserve RAM, but what would be reserving 8GB??

It's because you are running Home premium, which supports a max of 16gb of ram

Unfortunately, there is no work around except to upgrade to professional or higher

Solution to this problem Windows 7 "Ultimate" , assuming the motherboard, the new memory sticks and the Bios are working as it should.

1- Install the new sticks, turn on the computer and do not touch the Bios (will recognize them automatically, it should 99.99% of the times), just let windows start normally, if so, login as administrator.

2- go to "control panel" > "System > advanced system settings > advanced > under "Performance" effects, etc click on "Settings" > again click on "advanced" > virtual memory > click on change > and select "no paging file", will ask to restart > click YES > restart and continue last step 3

3- type under Start command "msconfig" > enter > click "boot" > advanced options > uncheck "Maximun Memory" > ok > apply > restart

4- if you followed all this steps on sequence from 1-3, now go to control panel > system > you will see your full memory ready to use.

Note: do not run any memory freeware checking software, will not help at all. Goodbye
