4gb ram 3 gb usable
i have win pro 64 bit with 4gb ram it says only 3063 usable. i think that my graphics card is using the rest as hardware reserved memory how to reclaim that 1 gb of memory??

Your startups as well as the background services in Windows are simply taking the first 1gb as well as some possible mapping out. Presently here I see 1.34gb taken off likely having a few things for that difference running the 64bit Ultimate.
If you were seeing a large drop when looking in the task manager>performance tab there you would then have to consider a problem was present. The first thing however would be looking at the startup items seen in the msconfig utility and simply uncheck anything you can disable without worry being able to manually start it up when needed; 3rd party mainly rather then anything video or sound related.
The fewer items to start with the less ram will be occupied.
What is your graphics? If it is an on-board chipset, then it possibly uses that RAM. If it is a dedicated graphics card with its own memory, then there is another problem.
if your graphics is on board then it must be using it but if not its another problem
Dinesh was correct there even with onboard video rather then a separate expansion in how shared system memory is allocated. If you have 256mb for the onboard Windows will likely match that by mapping another 256mb bringing the total to 512mb used.
Another factor not to forget is the fact that the 64bit Windows will place more data in the active ram seeing far less data swapping out to the drive where the 32bit relies on the paging file for supplimenting with the virtual memory. If a default 32bit 7 install runs at 400mb the 64bit equivalent uses about 300mb more to bring that to 700mb.
i have the same problem.
I had 1x2GB 800mhz (kingmax) ddr2 , and then i bought one stick more
now i have 2x2gb of same memory, but my windows 7 x64 says it is only 3,0 of 4Gb used.
I have indicated 128mb card

I would start by going here. This neat little MSFT tool will give you some good basic information on the weak link(s) in your system's performance which of course is the ultimate goal of freeing up more physical memory.:)
While the article talks about Vista the tool is available in Windows 7 and I believe can be accessed and run in W7 as indicated in the article for Vista.

Understand and improve your computer's performance in Windows Vista
By Stephanie Krieger
When presenting at a user group meeting last week, someone asked me if a low Windows Experience Index (WEI) score of 1 or 2 means that he should not use Windows Vista on that computer. The answer is "not at all."
One of my favorite capabilities of Windows Vista is that it scales itself to fit your computer to help give you the best possible performance. For example, if your computer doesn't have the graphics capability to effectively display the new Windows Aerovisual effects, Windows Vista won't enable those effects on your computer.
In this article, I'll show you where to find your computer's WEI base score and subscores, as well as how to interpret them. I'll also show you how you can use these scores to help know what to look for when buying a new computer, upgrading your existing computer, or troubleshooting performance issues.
Finding your scores
Here's how to find your computer's WEI scores:
- Open Performance Information and Tools by clicking the Start button , clicking Control Panel, clicking System and Maintenance, and then clicking Performance Information and Tools.
- View the Windows Experience Index base score and subscores for your computer. If you have recently upgraded your hardware and want to find out if your score has changed, click Update my score. If you don't see subscores and a base score, click Score this computer.
This image shows the WEI scores for the computer I used to write this column:
And that is all you're going to get with that motherboard unless it has the memory re-mapping option in the bios, which I doubt it does with that old SiS chipset (SiS 671/ 968) in it that only supports up to 4 GB of ram,
Universal abit > Motherboard, Digital Speakers, iDome, AirPace, Multimedia
Your problem is a hardware limitation, and nothing to do with Windows,
The system memory that is reported in the System Information dialog box in Windows Vista is less than you expect if 4 GB of RAM is installed
scroll down to the Workaround section and change the 8 to a 4 here,
and it explains why you're not getting the full 4 GB.Note When the physical RAM that is installed on a computer equals the address space that is supported by the chipset, the total system memory that is available to the operating system is always less than the physical RAM that is installed. For example, consider a computer that has an Intel 975X chipset that supports 8 GB of address space. If you install 8 GB of RAM, the system memory that is available to the operating system will be reduced by the PCI configuration requirements. In this scenario, PCI configuration requirements reduce the memory that is available to the operating system by an amount that is between approximately 200 MB and approximately 1 GB. The reduction depends on the configuration.
Basically without the memory re-map option in a situation like yours and as described in that link, you will have the same amount of memory available whether you run 32 bit or 64 bit Windows.
so I need to change some advanced options in bios, do I need maybe update it to newer version and what is the safer way to do it ?
my bios version is:
