To make full usage of 6 gigs of ram, you should be running Windows 7 64 bit operating system. The 32 bit will only see up to 3.5 gigs at most.

It is dependent on the hardware you have. The maximum RAM a 32 bits system will have available varies between 2.8 and 3.5 Mbs and even those figures are not definitive The rest is taken up with memory mapped hardware devices which must use the 4Gb memory space that is available to a 32 bit CPU and operating system. Different hardware will use varying amounts of memory.

There is nothing you can do about it except use a 64 bit operating system on a 64 bit CPU.

How are you measuring memory usage?
The memory gauge doesn't show all memory usage. Memory on the standby list and what is used for Superfetch is never shown. To see full usage you must subtract that labeled "Free" from the total memory displayed.

32 bit client versions of Windows have a 4 GB physical address space but a substantial portion of this must be used for memory mapped hardware which must have priority. Typically this will leave about 3.25 GB available but it is often less. If RAM is shared with the display system it can be much less.

To make full use of your memory you need a 64 bit OS.

1GB doesn't mean it's a fast card.
