Windows 7: 4GB installed RAM, 2.75GB usable =[

Windows 7

I believe that I can help here, Windows 7 uses 1.25gb of your memory as a cache, leaving you with 2.75gb of usable memory for other programs and software.

Nice necrobump

Your statement is incorrect. No offence intended of course. Disparities between the amounts reported as "installed" and "usable" come down to hardware configuration and hardware address range needs.

Don't concern yourself with that. Memory shared with graphics in this manner is still usable by other applications if/when they need it. You will also see in your screenshot that dedicated system memory is 0 MB. If that number was higher then it could take away from the memory available to the OS and applications. But since it is zero, there is no cause for alarm.

For some more detail about the problem H2SO4 just addressed, refer to my post here:

Windows 7 x64

I've got it again too with Win 7 Pro x64.
My desktop, which I was referring to last time at the beginning of the thread is fine, but my laptop, which has 3GB of installed RAM is only seeing 2.75GB as usable. I've checked the Max. Memory which fixed it last time but to no avail.

- I am using x64.
- I've got a 256MB NVidia 8200M G, which again is using 1151MB shared memory.
- No RAID as far as I know, after all, it is a laptop with a single HDD.

Any other ideas?

4.0GB - 1.25GB = 2.75GB usable I think that says it all.:)

Activate memory hole remapping in BIOS and you will get the "harware reserved" memory back.
