If you can find a credible article that proves me and everyone else that has read about this wrong I welcome it..... | |  | |  | |
Even though it says it only works on Server, that's not true; I've used it with XP. This explains it well:
How to Set the /3GB Startup Switch in Windows
And if the standard 1GB to System/3GB to applications makes your system unstable, you can tune how much you give by following this article:
How to use the /userva switch with the /3GB switch to tune the User-mode space to a value between 2 GB and 3 GB
or this one:
How to Set the /USERVA Startup Switch in Windows
Then there's these articles explaining just what it's actually doing:
The Old New Thing : The oft-misunderstood /3GB switch The Old New Thing : Myth: The /3GB switch expands the user-mode address space of all programs
Standard procedure for servers with 4GB
RAM running Windows Server 2003 Standard is to add the /3GB switch to them. The memory "seen" jumps from just over 3GB by default, to 4092MB.
I've done this many times in my environment of over 200 servers.
After all that, I forgot that the /3GB switch really isn't what you're looking for!!!
Forget my instructions above. In Vista it's going to make your system really unstable. Instead of using the /3GB switch in your boot.ini you have to enable the Physical Address Extensions in the exact same place. So instead of /3GB switch, please append this switch to the line just under your [DEFAULT] entry in boot.ini:
Here's a technet article explaining what it's doing:
Large memory support is available in Windows Server 2003 and in Windows 2000
Hope that helps, and I hope you're not thoroughly confusered.
