ok , first here are my specs :

i3 3ghz
8 GB ram DDR3
NVidia GeForce 9800 gt 1 GB DDR3
160 free gb in HDD

i'm running windows 8 64bit .every time I run a game it doesn't use more than 1 gb of ram (though games are supposed to use up to 3 gb at least ) and runs slowly , when I open the task manager it tells me that there is 6.4 gb available but it doesn't use it .
How do I allocate more ram for games ?

I noticed (from the task manager) , every game I run it runs in 32 bit mode (like this : Assassins creed 3 (32bit) , Battlefield 3 (32 bit) ...) .

(I forgot to mention that when I run any game, cpu usage goes up to 90 - 100 % while ram usage does not pass the 1 gb )

here are some photos showing my problem :





please help
thanks ahead

Are you playing the game online or only on your computer? The 3 GB they recommend is for your system. That takes into account the amount your system will use as well as any background services. Depending on the settings you have your graphics set on for the game, 1 GB may be all it needs. Don't worry too much about the memory usage, look at the history for your CPU usage. From what I have read, the speed of the processor has a greater impact than RAM. If it is constantly at 100%, then we have solved the lagging problem.

I`m not surprised.
It will be down to that old 9800 GT graphics card for starters.
It is causing a bottle neck, a choke point.
Plus since most games use the Gpu for physics and the graphics it will be having a hard time, most likely it cannot cope with the games depending on the graphics settings and resolution you are trying to run the games in.

It is likely that the gpu of the graphics card is trying to off load some of the physics calculation of the game and why you are getting a 90% usage of the cpu.
The cpu will take a major hit if this is the case leading to 90% or more usage.

And the cpu is an i3 intel, so that does not help as well.

Most people would recommend an i5 or i7 for playing with games.
And a better graphics card.

Both causing bottle necks.
Cpu and the Gpu.

appreciate the answer
but you understood wrong , yes the minimum is 3 gb for most games . but if you you have more the game will use what it needs . my friend
told me that he has 4 gb ram (windows 7 32bit) , but games consume up to 2.5 gb on his computer while I have 8 gb and it only consumes
1 gb .
another thing , if the CPU usage keeps at 100% for a while , it will be be damaged
thanks anyway , I really appreciate the answer

I don't think its the GPU , I used to play games on my computer (same specs , except only 4 gb ram) on windows 7 32 bit . they were
working fine , like battlefield 3 (used to be able to play it on High settings, and would use more than 1 gb of ram) , then I upgareded to windows 8 and added 4 more GB of ram . but it wont use more than 1 gb . why ??

Battlefield's system requirements are higher than that of Assassin's Creed. Especially if you were playing on high settings, that would explain using 1GB+ of ram. I dont believe there is any actual problem here. The system merely does not need any more RAM to use. So long as the operating system recognizes the memory and memtest86 doesnt come back with any errors, you should be good to go.

Is your friend playing Assassin's creed as well when he is using the 2.5GB of memory?

tell you here . its supposed to but it isn't , all games don't (neither any app or program) , so instead of running smoothly they lag
