4 gb of ram in win 7 rc 32x

[kopka]

I recently installed windows 7 32x on my laptop
dell studio 1555 which have 4 gb of ram and in computer summery it writes that there is 4 gb of ram and (2.9 is usable).
In prevoius threads i read that windows7 32x support 4gb of ram and i saw that in bios have option of memmory remmap that should repair these issue but in bios i don't have the this option.

what else i can do to fix that?

32bit version supports only 3GB RAM!

Is it worth to change to windows 7 x64
i mean in x64 he will recognize 4 gb of ram but maybe i have drivers and other programs problems i read that x64 isn't very stable version and will i have drivers problems?

What are the advantages and disadvantages of the x86-64 version?
The good:
* Support for more than 3 GB of RAM (with proper motherboard support; some older chipsets, like the Intel 945GM, do not allow the addressing of all 4 GB, even if your OS supports addressing all 4GB)
* Potentially faster execution resulting from the ability to operate on larger chunks of data and the addition of new registers (x86-32 being a register-starved architecture, this helps). This speed up requires that the program be compiled natively for x86-64, and the actual gain will vary from program to program.
* Future-proof. 32-bit will eventually die out one day. Could be many, many years down the road, though.
* Slightly more secure than the 32-bit version.
The bad:
* x86-64 requires more memory (and disk space) because the code is inherently larger, and because Windows has to also load the Wow64 libraries into memory (the stuff needed for backwards compat with 32-bit programs) (and keeping an extra set of DLLs around for 32-bit programs will eat up more disk space).
* All drivers must be signed. This is good (for security) but also bad (for small custom software that can't afford driver signing).
The ugly:
* You have to make sure that you have 64-bit drivers. Some manufacturers, such as Dell, haven't released 64-bit drivers for some of their older hardware.
* 32-bit shell extensions won't work.
* 16-bit programs don't work (not really a limitation of Windows, but of how AMD designed x86-64).

Better explained!

x64 is very stable, if you have the right drivers

look to see first if there are drivers available for your hardware, before you install - download and save them to a separate partition or external drive/disc.

it would help us more if you filled in your system specs - goto UserCP, and 'Edit System Spec'...

no it doesnt, 32bit OS can address 2^32 bytes of memory. This gives you 4GB of memory, that includes ram, graphic card ram, xram (if you have it) and all other memory you might have inside computer (like some nics have own ram etc).

Thank you.

main problem why people have 3gb of usable ram (if they have 4gb) is for example. You have graphic card with 1gb of memory, so 4gb-1gb = 3gb. Throw in some old PCI card and you can get most of that 4gb ram being usable

I'm running a dell E520 w/out any issues in Win 7 x64. Check out my specs. Everything Dell is running fine under the Vista x64 drivers.

Step ONE - Fill out your System Specs - help us help you.

Step two. Fill them out completely.

.
The memory remapping feature is needed for the 64-bit OS not the 32-bit. The 32-bit OS can use a maximum of 4 gb, however that includes memory address space assigned to hardware such as the video card. When the OS reports that 2.9 gb is "usable" it means that it was necessary to set aside 1.1 gb for hardware. There may be an option in the BIOS to change the amount of memory dedicated to the video card. If so you can reduce it, which will increase the amount of reported "usable" memory.
