will increasing ram automatically increase shared memory on integrated video cards ?

[Prakharj]

Hello everyone ,
I have 1 gb ram at present and no discrete graphic card . I am thinking of buying 2 *2gb kingston 800 mhz ram thus total 4 gb ram . I have intel 945GM chipset integrated graphic card with 64 mb system video memory and 190 mb shared system memory . processor is intel pentium dual core e2160 1.8 ghz ( but it runs at 1.5 ghz dont know why )

I have following questions if could please answer :-
1 Will the shared system video memory increase automatically if i installed 4 GB ram ?
I have used 2 GB ram previously but the shared memory was the same (190 MB) so I am
wondering if 4 GB ram will increase it or not .
2 my windows experience index are :-
processor 4.2 memory 4.2 graphics 2.4 gaming graphics 3 hard drive 4.3
a) will the index for graphics and gaming graphics increase ?
b) how much performance boost can i aspect in web surfing and gaming ( at present i
can play igi 2 at very low settings and resolution )
3 i run win 7 ultimate 32 bit , is it worth it to run 64 bit in 4gb ram ? does the processor work
double fast in 64 bit ? may be this is the reason my processor only running at 1.5 ghz when
it is supposed to run at 1.8 ghz?
4 is it possible to increase shared memory if it doesn't increase automatically ?
(my bios does not support any type of overclocking or voltage changing whatsoever and i
found no settings about shared memory )

I am sorry to ask so many questions and you could obviously chose to answer only few of them .
I sincerely thank you for your time and concern .

1) It should dynamically adjust when required I believe.
2 a) no it will not increase
2 b) Surfing should become faster, and performance gain in IGI2 depends on how the game is designed, should get some FPS increase but cant say for sure.
3) 32-bit only has addressing space of 4 GB, and hence you will not be able to utilize ALL of your RAM @ 32 bit (will probably utilize around 3.75 gigs I think)
4) i'm not sure, i really think it should dynamically adjust

Advice to OP: get a cheap and old used graphic card, even something for 20-30$ will be better than intel 945GMA

1) The 945GMA can address up to 224MB depending on the exact version (this chipset was a poor performer when it came out.)
2) The actual increase in RAM for the whole system ought to help odds are you are doing a lot of writing to the page file with only 1GB of RAM. performance GPUwise anyway I doubt will increase
3)64 bit advantage is to address more than 4GB of RAM.
4)The only way to adjust that is the BIOS
