Normally XP and Vista 32 bit will only address up to 2GB memory for
applications and 2Gb for the kernel. The 3G swicth will change this
to 3GByte for applications and 1GByte for the kernel. This will make
one Scorpion instance able to use 2.0-2.5 instead of 1.2 - 1.4
GByte. The feature is supported fully from Scorpion 7.0. Adding
large 3G memory to Windows XP
If we add a boot.ini switch /3GB, then XP is allowed to address
up to 3GB for applications.
Manually edit your boot.ini file by adding " /3GB /Userva=2900"
to your boot.ini (no quotes). Your boot.ini is normally read only
and you will need to change that temporarily while you edit it. To
Edit it manually you can find it on the root of your system drive or
go to system properties/advanced tab, settings under 'startup and
recovery' section, then hit edit.
Typical :
multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Windows XP
Professional" /FASTDETECT /NOEXECUTE=OPTIN /3GB /Userva=2900
Yours maybe different, the only thing you should change is add /3GB
/Userva=2900.
To enable the 3GB switch on Windows Vista™ or Windows 7:
-
Right-click Command Prompt in the Accessories
program group of the Start menu. Click Run as
Administrator.
-
At the command prompt, enter "bcdedit
/set IncreaseUserVa 3072"
-
Restart the computer.
To disable the 3GB switch:
-
Right-click on Command Prompt in the Accessories
program group of the Start menu. Click Run as
Administrator.
-
At the command prompt, enter "bcdedit
/deletevalue IncreaseUserVa"
-
Restart the computer.
Note: Its safer, especially if using a video card,
framegrabbers with lots of memory (like 640-768MB) to set it to 2.5
or 2.75GB instead of three. |
