How would i be able to dedicate one core for windows 7.
i want to load windows 7 up completly on one core, and not change it once i get in. so that i know core 1 is completly free.


what i want to do is, have my 2nd core completly free after windows loads.
not sure wich process is running for windows so i can change its affinity to core 0.
and i am still supersticous about doing it that way.

would it be a reg setting or a system file that would need to be changed? so windows knows only to boot off one core? where would i find something like that?
 
There's no reason to want something like this.
 
What's your reason? Seems stupid to do this.

Go to run, type in msconfig, then go to the boot.ini tab (i think it's called that), click on advanced options.

Haven't tried making windows load on 1 core so i'm not sure if it will work
 
thanks i'll give that a bash.

i got a performence boost by dedicating each core for specific applications. By booting windows off a single core and dedicating the other specitically for something else, i can get maximum performance on that core.
at the moment windows is using both cores when i dont need it too and wasting what i could be using for something too get that extra.

i set core 0 and core 1 to each application and got a nice boost in speed for the specific application and no loss from the other one while they were running together, but windows was still on both cores wasting cpu usage.
 
It is always useful to allocate a single core per resource intensive application, but only if you will be running processes that will be using 100% of an available core, such as media encoding (you can then run it on 100% usage without having your kernel lag behind)
 
ya, thats why i am trying to test and get as much performence i can get. at the moment even though i have increased a bit more performance, it still top spikes at 100% cpu usage. i dont need win7 to run on both cores, and want to test and see what happens when its in this state.

during boot time the bottleneck would be your harddrive not the cpu. So this would be pretty useless imo.

what does booting have to do with anything here and bottlenecking?

i dont care if my boot took 20 mins. its got nothing to do with what i am doing

If you want to do this, and I don't really see it helping much, then you'll probably need to use the Resource Monitor (in Task Manager, under Performance) to identify which processes or services are spiking your CPU usage and then set their affinity.
 
I have a reason

I want to dedicate a processor to the OS and have nothing else run on it so I can have a more responsive system.
Windows has gotten to be very laggy since vista. :mad:

Task Manager -> Set affinity for the process you want.
You seem to be a good thread necro-er in the making.
