Forcing Vista to run on a single core

post #1 of 16
Thread Starter 
I was wondering if there is a way to run Windows Vista and any other OS on a quad but only use one core? I want to know what kind of performance jump you get with sya a dual core system versus a single core system.

For XP:
MSCONFIG -> Boot.ini -> Adanced Options... -> /NUMPROC = [SOME NUMBER]

For Vista, it's almost the same thing.
Once again...

For Vista:

Right click cmd.exe to run as admin > type in "msconfig" > Select the boot tab > Advanced options > number of processors = x

As mentioned above its pretty much the same thing in XP

I am 97.3% sure it sets what the OS is allowed to use. I remember setting my RAM to 2GB and spent an hour wondering why it was using only 2GB after upgrading to 4GB. Try it and see.

you can just type msconfig in the search and it will open, i do it all the time, no need to run cmd.exe as an admin.

If that is true, reboot and it should be greyed out. OS should then be using as many resources as it can.
