4gb ram and windows 7

But suppose if you are still using bit of Windows and have upgraded your RAM and still insist of keeping your Windows as you have tons of collections of stuff installed. This is where the patch comes handy. So how does this magically tweak work? It is simply. It acts as a translator , trying to break the limit of bit. Instead of accessing directly , it uses PAE to acts a translator to address memory location beyond the 4GB realm.

Remember that bit processor can only address 4GB of memory space , this extends it to bit or sometimes up to bit. There is one — you are still limited by the law of physics and computing. Since our system is bit , therefore the instructions are still in bit and we are still bounded by bit instructions. This is because that the instructions are in bit still. Firstly you would have more memory which means that you could run more applications on your bit system. Imagine if you want to run photoshop and lightroom concurrently , it would not be possible.

Click on Start and then right click on My Computer. Choose Properties from the menu. This opens the Properties window for your computer.

Then, close the Properties window. Click on Start and then on Run. This opens the System Configuration window. Click on the Boot tab and then click on the Advanced Options button. Click on the Maximum Memory option and type in the maximum amount of memory you noted earlier in the My Computer Properties window. When finished, click the OK button, close all remaining windows that you have opened, and restart your computer. Windows 7 bit does not always correctly identify the amount of memory you have installed in your PC.

You can fix this problem by manually specifying how much memory Windows 7 bit should use by changing a value in the BOOT Advanced Options window. Assuming you have no hardware or software errors, Windows 7 should then be able to correctly identify how much memory you have installed and the maximum amount of memory to use at boot up. Agreed, native 64bit will run smoother and more efficient so to speak on a 64bit processor, and you also mentioned about the 4gb of ram, definitely go 64bit.

Just make sure there is no drivers issues with your hardware on win7 x64, do a bit of research on your particular laptop model and see what others have to say about win7 The virtual address space is divided so that 2 GB is available to the application and the other 2 GB is available only to the system. The 4-gigabyte tuning 4GT feature, formerly called 4GT RAM Tuning, increases the virtual address space that is available to the application up to 3 GB, and reduces the amount available to the system to between 1 and 2 GB.

For applications that are memory-intensive, such as our FSX app , the use of a larger virtual address space can provide considerable performance and scalability benefits.
