Windows 7 not recognizing full 4 gigs

Welcome to the Se7en Forums! stevo7390

You likely are running the 32bit 7 there which will drop some 450mb of usable ram right from the start out of the 4gb total. That is mapped out to hardwares due to the 32bit kernel. So you have to expect that.

Depending on what you are looking at like the taskmanager you then have to take into account the OS background services and all startup items that grab some more. That can chew up another 800mb plus. That brings you down to at least 2.8gb of ram available maybe less.

Hope you are following that so far! For the remaining a look at the startups should show one or more using more ram then the rest to see where the rest is being taken up since 2.4gb is still a little on the low side.

Hello Stevo,

Welcome to Seven Forums.

Just guessing that you are running 32 bit windows. If your not sure, look here: Control Panel\All Control Panel Items\System. 32 bit has address space for 4 gigs total ram and some of that space is used by hardware. The ram from the dual 8800's for instance if they're 512MB each your down to 3 gigs and still all the other hardware to go. The only way to utilize all 4 gigs is to go to 64 bit.

Hope this helps.

Edit: I type too slow.

I could tell right off you are in the 32bit Windows since the 64bit 7 here shows 4094mb when looking at the performance tab! You simply have to remember the deductions seen with the 32bit kernel to understand why that shows a lesser amount.

With the 32bit 7 here I end usually seeing about 3.58gb before the remaining deductions of system processes, startup programs, etc. presently show some 2448-2476mb available out of the 4bg total seen by the 64bit kernel depending on what I am doing at the time before loading anything other then IE for example.

If you bought the retail package that would include the 64bit disk along with the 32bit there. Otherwise you would need to buy the 64bit separately now.
