Only 2.5 GB available RAM out of 4 GB 64 bit OS

Hi

I have installed windows 7 HP 64 bit on a machine with 4 GB of DDR3 RAM, although in msinfo32.exe it says that i have only 2.50 GB available.

Hopefully I have attached a screenshot of the msinfo32 window (I am not sure if it worked or not) to let you see the problem.

The total physical memory seems correct yet the available memory should be more, shouldn't it?

Thanks

Whenever I set it to 0 and go back in, it has changed to 256 mb. I don't want to restart yet in case it has to boot with 256 mb ram

Take a snip of the color bar in Resource Monitor > Memory tab and post it here Then we will see clearer.

Well, it adds up to 4GB. The number you showed earlier is what is currently available (which is the dark and light blue).

BTW after changing the system config to 0 RAM and rebooting, windows couldn't start so I changed it back in safe mode.

You said that - LOL. But I am glad you are happy now, at least I hope.
