Windows 7 Ultimate 32 bit

[djokica89]

As u guys see i have problem... Im using Windows 7 ultimate 32 bit and i have 4 GB ram. When i go right click on my computer then Properties i want to check my ram. And when i saw i dont get it.... It says Installed Memory (RAM): 4 GB (3.25 Usable).... Is there any way to fix it ????

Unfortunately a decision made by Microsoft several years ago on how Windows is programmed, prevents the 32 version of the OS from addressing a full 4GB of RAM, so unfortunately you are limited to that 3.25GB. Usually, the left over RAM is used to make other hardware, like you video card, run better, so you are still getting you moneys-worth.

Don't feel too bad. I have Windows Pro X64 with 4GB or RAM and mine says

Installed memory (RAM) 4GB Usable 3GB.

1GB has been appropriated for something else and there is nothing I can do about it.

Bummer.

I found a fix to get full 4 GB of RAM and i tested it and its working... But im gonna turn it off because u sayd: Usually, the left over RAM is used to make other hardware, like you video card, run better, so you are still getting you moneys-worth.

And i Trust u

Really? What did you do?

On 4 GB systems the above is just an alteration to the display. RAM is still taken up by the hardware, there is no way around this. 32 bit hardware has a strict limitation on the addressing space it can allocate. This is not something Microsoft programmed into Windows, this is just how the x86 platform works. 64 bit also has the same problem, it is just that the addressing space is over 8 TB (for a full 64 bit address which most CPUs do not have). PAE is pretty much already turn on, on modern CPUs that have hardware DEP. DEP requires PAE on 32 bit systems because DEP stores the execution bits beyond the 32 bit space.

Furthermore, going above 4 GB on a 32 bit system is nothing but a cruff. You would be better off going with 64 bit. It is a lot more efficient with larger memory sizes then 32 bit could ever be.

Is there anywhere I can rad about what the 1GB of my 4GB ram is used for? I've gotten bits and pieces of info from various places but it would be nice to read exactly what Windows 7 X64 uses it for.

Start > type "resource monitor" > Memory Tab > Physical Memory.
No doubt the 1 GB is "Hardware Reserved" to get that 1 GB your motherboard and BIOS must support 64 bit (in the CPU and chipset) and have a memory remapping feature.

The real ? for dj, that system that you LOVE, running ok?
That's all I care about!

All hardware you have has to be mapped into memory to access resources, which is between 3-4GB in an x86 system. In an x86-64 system this memory hole is remapped over 4GB, assuming your BIOS supports it and you have a 64-bit OS and your hardware is compatible (which it probably is). Also, in a 32-bit system, apps can only access 2GB. With a 64-bit system, this is lifted and 7 can also access more memory for itself.
