How can I enable PAE on Windows 7 (32-bit) to support more than 3.5 GB of RAM?
Is there way to enable 4 GB RAM in 32-bit Windows OS?According to the official windows memory limits, Win 7 only supports 4 GB of RAM. I, however have been reading some forums and some say they are using 8 GB RAM with good performance. I am wondering if I can use 8 GB before I purchase.
Solution:
You can install 8 GBs on 32-bit system, but you won’t be able to use it. You need a 64-bit system to do that.
