Get 32-bit Vista support 4GB or more

You’re probably wondering why I picked a number as horrible as 3.5GB? Why not 4GB? Well, there’s a really technical explanation for this but to make a long explanation short, 32-bit operating systems can only handle up to 4GB of memory. Along with the RAM, you also have other memory-mapped devices such as your video cards. The memory used counts towards the 4GB virtual memory address capacity of a 32-bit operating system. But actually, the world does not end at 4,096 megabytes for 32-bit Windows Vista users anymore because the Arsgeek is here to save the day.

If you’ve accidentally bought 4GB of RAM, this may be a good idea. And I say may because many 32-bit operating systems begin to lose efficiency as they surpass the 4GB mark. For that reason, if you have less than 3GB RAM, it’s not necessarily the best idea to go out and buy some more RAM. If you want to utilize more RAM (between 8GB and 128GB), you can always switch to 64-bit Windows Vista. Alright, enough babbling. Let’s get started.

Steps:

1) Access cmd: Click on the Start Pearl > type cmd in the Search Bar > and press Ctrl + Shift + Enter (this allows you to run cmd in administrative mode)

2) Type BCDEdit /set PAE forceenable

“BCDEdit is a boot configuration editor for the command line. Using the above command you’ve just enabled Physical Address Extension (PAE) which can address memory larger than 4 GB. â€"

i guess i can now get another 2gb and not lose a gig

Last I checked it was for server versions only. There is a noticable performance hit when used since it requires an additional mapping level. It may cause driver issues as well.

Not a bad find. Anyone tried it ?
post #7 of 8
I suggest just getting x64 vista. It comes with almost any higher-level version of vista and the drivers for it are not really bad at all now. My audigy and X1900 work great, and I believe they were the two most problematic hardware devices originally.

Yeah all x64 drivers i've seen lately are on par with their 32-bit cousins, if you want 4gb RAM just get the x64 version.
