Windows 7: Is my win 7 64bits using the whole ram?

Is my win 7 64bits using the whole ram?

Hi guys!

i had to help a friend with a laptop like mine... while fixing the problem i notice that the laptop is way faster than mine, EVEN when it was only 2gb of ram while mine is 3gb of ram!.

well after checking the whole system trying to figure it out why it is so faster... then i discovered that it was a windows 7 64bits while mine is 32bits!

then i decide to upgrade mine, i got 4gb of ram and a new hdd to install the win764bits.

i proceeded wiht the installation of windows 7 64bits, ifter the insallation finished and enter to desktop for first time i clicked in computer properties.

since i have heard that 32bits version cant handle more than 3gb, anything over 3.5gb would be wasted, knowing that i thought that with a 64bit version all the ram then will be properly used but in "computer properties" (in the fresh install of windows 64bits, in "installed memory (RAM)" it says 4.00GB(3.37GB usable)

is that correct?

should not show me 4gb usable?

3.37 is correct and normal. The operating is using the rest to operate.
A good way to see what your ram is doing, Resource Monitor.

Oh ok!
i thought the 3.37GB was the amount the OS can handle!
know i understand is the amount available for the user, ok!

i thought something went wrong with my 64bits version.

Thank you very much friend!

On x64 this can happen as well if you have an on-board graphics card, where it takes part of the main memory as if it were the video RAM. In that case, it's normal to see less usable RAM. That also happens on x86, but there are additional reasons that limit memory even more.
Anyway, Windows (or if that's the case, any other OS for the matter) cannot use more than those 3.37GB in your case, the rest being used as the video memory.
