Windows 7: Memory

Memory

I have 8 GiGs of Memory and only 3.5 GIGS Register. Why doesn't all 8 GiGs show up? I know Windows requires at least a GIG. Thanks.

I'm going to go with the fact you are running a 32bit system and the max it can handle is 3.5!!

You need 64bit or Linux to use all 8!!

You’re currently running a 32bit operating system therefore you will only be able to use just under 4gigs of Ram. 64bit operating systems basically have no limit to how much Ram is used.

-A 32 bit OS can only address 4Gb of memory. Some of this is then allocated to hardware devices, usually dropping the available RAM to 3.25Gb or 3.5 Gb.
-The addressable space also applies to programs, giving a 2Gb limit of RAM to any one process. This means that 32 bit Photoshop can only ever access up to 2Gbs of RAM.
-Drivers are always a concern. Drivers for hardware usually have a 32 bit version, and there is usually not a problem with 32 bit drivers (finding or using).
-A 32 bit OS has a lower memory requirement to run. For Windows 7, the minimum RAM needed is 1Gb

Nigsy is too fast for me :P

Several, including Windows 7 x64 Ultimate
 
 

You only have a 32 BIT system, it can not use more than 4 Gbytes, total.

Not strictly true, it's limited depending on which version of Windows you're running.

Memory Limits for Windows Releases (Windows)

Win7 Pro, Enterprise, and Ultimate are limited to 192GB
Win7 Home Premium is limited to 16GB
Win7 Home Basic is limited to 8GB
Win7 Starter is limited to 2GB

Well, it IS a Windows 7 forum after all...

The important point is that you can be far from unlimited even if you're running 64-bit. A 64-bit W7 Home Premium install is limited to 16GB for example.
