Maximum memory in windows 7 Professional 32-bit

Question

What is the maximum amount of memory I can install in Windows 7 Professional 32-bit?

Answer 1

Technically 4GB (because with 32 bit you can address 2^32 bytes). Practically a little less (net avaiable) since the system and the operating system need some. But in the usual terms, you can upgrade them to 4GB.

Answer 2

You can have as much as your motherboard supports and using techniques such as Physical Address Extension (PAE) You can use it all - however, on most non 64 bit machines, you can use between ~3.2GB and ~3.5GB which depends on many factors such as shared graphics memory and the amount of additional cards and devices you have (they all take address space).

Answer 3

4GB ram. Give or take, because it includes your graphics card and other things, which all count towards the hard 4gb limit. Upgrading to 64bit will give you 4EB of ram, which is far more than you'll be able to use.

Answer 4

I have a max of 2.8 GB even though I have 4GB installed and Windows 7 64 bit.
