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?

In order for the full 4GB to be available, your laptop has to be able to remap the upper 1GB of RAM above the 4GB mark. Otherwise this area (or part thereof) is required for fixed hardware addresses, and can't be occupied by RAM. If the maximum RAM complement your laptop can have is 4GB, there will e no remapping capability. If it can handle a larger amount, there should be a setting in the BIOS to remap or relocate memory, look for that and enable it. If you aren't certain, post the laptop brand and model & we can search for specs.
