What lines do you add to the Boot.ini fire in XP so that the system will use more than 2 GB of RAM. Will this actually work? Will I benefit from 3 Gb instead of only 2?
Update: How high can I set the switch? The example I saw was: /NoExecute=AlwaysOff /3g
32 bit Operating Systems will use anywhere from 3 to 3.5 gigs of ram without doing anything..(provided the mobo is designed to use it)
You are thinking of the switch that causes a program's 4GB virtual address space to be divided into blocks of 3GB for the code and 1GB for the OS instead of the default 2/2. Only programs that are coded to take advantage of the 3GB address space can use it. The most common program I can think of that uses the 3GB block is SQL Server.
That switch is of no practical use for a desktop machine.

What ua said.
Yes. To the OP, xp and vista 32bit are limited to 4GB memory, not 2GB.Quote:

I upgraded my rig from 2 to 4 gigs...Vista 32-bit ( windows 7 ). I didnt see any diff in boot up time, programs ran the same , games do load up a big faster, but not alot.
Not really worth it.
It depends on the apps and how many of em you have open at one time:pQuote:

With only half the memory, I imagine it would run at paging file disk speed.
With 4GB of memory, it wouldn't run.
agreed. even just running a dual monitor makes the extra 2 gigs worth it and even more so when games are running.Quote:
