I'm using Windows XP, home edition, SP3 and I'd like to try using the
/3GB switch to use more of my 4GB of RAM for Photoshop.
My notes indicate: On systems that have 1 GB or more of physical memory,
two startup switches can be used to allocate more memory to applications
(3 GB) and less memory to the operating system (1 GB).
The /3GB switch is used to effect this allocation change. The switch is
entered in the system’s boot.ini file and takes effect after a restart.
C:\boot.ini
[boot loader]
timeout=30
default=multi(0)disk(0)rdisk(0)partition(1)\WINDOWS
[operating systems]
multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Microsoft Windows XP Home
Edition" /noexecute=optin /fastdetect /3GB
The last line of my boot.ini file looks like this:
Edition" /noexecute=optin /fastdetect /usepmtimer
The AMD driver for my X2 dual core processor added the /usepmtimer ,
because the default processor timestamp-counter (TSC) is not
synchronized properly between cores, and causes certain applications to
run at double speed.
So where do I put the /3GB?
Do I make the last line of my boot.ini look like this?
Edition" /noexecute=optin /fastdetect /usepmtimer /3GB
Is this going to work or am I just asking for trouble?
Thanks.
