32 Bit Windows 7 and 4 gigabytes of RAm
is there a way to force the 32 bit versions of windows 7 to use more than 3 gigabytes of RAM.

No... the only way to fully use more than 3Gb is use the x64 version. X64 version is so stable and compatible (i run it on 2 gaming systems), there really isnt a reason to run the 32bit version anymore.

wasn't there a command you could use im XP to make it use more than 3 gigabytes?

First, you can see how much RAM Windows has accessible to it in the System Properties dialog, or Task Manager's Performance page. Limits on memory and address space vary by platform, operating system, and by whether the IMAGE_FILE_LARGE_ADDRESS_AWARE value of the LOADED_IMAGE structure and 4-gigabyte tuning (4GT) are in use. IMAGE_FILE_LARGE_ADDRESS_AWARE is set or cleared by using the /LARGEADDRESSAWARE linker option. In addition, Limits on physical memory for 32-bit platforms also depend on the Physical Address Extension (PAE), which allows 32-bit Windows systems to use more than 4 GB of physical memory. For more details, you can refer to this link: http://msdn.microsoft.com/en-us/library/aa366778(VS.85).aspx I hope this can help you. John

Ok do edit boot.ini for this? Enabling PAE Windows automatically enables PAE if DEP is enabled on a computer that supports hardware-enabled DEP, or if the computer is configured for hot-add memory devices in memory ranges beyond 4 GB. If the computer does not support hardware-enabled DEP or is not configured for hot-add memory devices in memory ranges beyond 4 GB, PAE must be explicitly enabled. To explicitly enable PAE, use the following BCDEdit /set command to set the pae boot entry option: bcdedit /set [{ID}] pae ForceEnable

Here's the story:All 32-bit client versions of Windows (not just Vista/XP/7) have a 4GB address space (64-bit versions can use much more). That's the theoretical upper limit beyond which you can not go.But you can't use the entire 4GB of address space. Even though you have a 4GB address space, you can only use *around* 3.1GB of RAM. That's because some of that space is used by hardware and is not available to the operating system and applications. The amount you canuse varies, depending on what hardware you have installed, but can range from as little as 2GB to as much as 3.5GB. It's usually around 3.1GB.Note that the hardware is using the address *space*, not the actual RAM itself. If you have a greater amount of RAM, the rest of the RAM goes unused because there is no address space to map it to.-- Ken Blake, Microsoft MVP (Windows Desktop Experience) since 2003 Ken Blake
