Installed memory (RAM): 4.00 GB (3.75 GB usable)

I have Windows 7 Ultimate 64 bit, and I was wondering why my computer tells me that 3.75 GB out of 4 GB of installed RAM is usable. I've tried unchecking "Maximum Memory" under boot using msconfig, but it didn't change anything. I know its a pretty small thing, but please help.

It is most likely your video card using some shared memory.

Video Card RAM, PCI cards, ACPI, etc. It uses the rest for its own memory and is not available for programs to use.

100% normal

It would be normal if it was x86, but this is x64... ?

very true the only other way to solve your issue is to add more ram if you look at your vid card you will see some memory has increased

In my case im running 1 gb card 8 gigs of ram i only use about 6.58 and the rest my card has which it bumps to 2.4 ghz

That's weird. Cause I have x64 with 8GB installed and Windows says 8GB usable for me. Maybe he is using older hardware?

Perhaps you don't have video cards and other hardware using shared memory. Could this be the case?

Im not using old hardware just built this rig 2 months ago im using a hd5770 im on a 64 bit os my board already has a 1gb intergrated 128 mb chip it could be more then just my card using that extra ram but my components use it as i said it shows a bump in ram setting for my vid card 1.5 bumped to 2.4

That right there would be the only explanation of where the other ram went

and the .5 comes from the onboard memory as well

I have never seen any version of windows that let you use all the ram unless you fooled around with it all version of windows even the 95 didnt use all the ram

reason the other ram helps accelerate other hardware to work more efficient

and if you found a way to use all your ram that is one hell of a job you did on getting the system to reconize because with all the pc's and windows i used i could never achieve all my ram to just go to system instead of dedicated hardware

just my opinion could be wrong especially now days
