Dual core cpu, just 1 core working :s.

snowdog · 23 Sep 2007 at 18:01

It properly detects the cpu, but only 1 graph shows in taskman:

Any idea's how to fix it?
Don't say new install that isnt an option.
Previous cpu on this windows was a p3 800mhz.
Got newest bios, amd drivers&optimizer, etc...

Drop down the "computer" tab on the bottom screen. (Device manager)

Should say ACPI Multiprocessor PC

helmutcheese · 23 Sep 2007 at 18:07

Tidy your desktop, the CPU cant handle it and has shut down a core

mattyrigby00 · 23 Sep 2007 at 18:07

go on "computer" then go on uniprocessor pc or w/e then press update driver and choose ACPI Multiprocessor PC, if it doesnt show up or work then i have no idea.

snowdog · 23 Sep 2007 at 18:08

It says ACPI-PC (advanced configuration and power interface).
Not multiprocessor like my own pentium D.

oh not my pc btw my dads pc.

mattyrigby00 · 23 Sep 2007 at 18:09

when you press update driver on the properties of it, does it allow changing to acpi multiprocessor pc?

Ull need to update the driver,

If you cant find it, you will have to format the pc and press F5 when the windows cd loads and pick acpi multiprocessor yourself.

snowdog · 23 Sep 2007 at 18:13

I can only pick these 2, how can I get the newer acpi driver?

Camalot · 23 Sep 2007 at 18:15

It a reformat of windows i think, and press F5 when the windows cd is loading (same screen you press f6 to load sata drivers) and choosing the driver yourself.

Thats what i had to do, anyone else know a better way ?

Is there a way to force to load a new HAL without a new windows?
As it's the hal loading the acpi drivers, i mean is it possible to force the hal to detect a new acpi driver?
My dad will kill me if I reformat his pc, but I want to play supcom without severe lag on his pc

I don't know mate.

When i swapped OS on my laptop i lost one core, and i had the same issue you did. The only way i know is to format.

Had the same problem on my PC when i installed a dual core, was told here i had to format windows.

Installing my intel dual core was fine tho, didn't have any of this trouble.

It's already showing 2 cores in the Device Manager,

to make it show both cores in the Taskbar try this:-

Start > Run > then type msconfig

goto Boot.ini and then advanced

and then on Numproc select 2.

Apply and then restart.

Can't select 2, as its greyed out.

On my own pc I get this choice:

Can I somehow copy over the HAL files (hal.dll) from my own pc to my dads in dos, I mean would that work?

mattyrigby00 · 23 Sep 2007 at 18:32

try unticking the "show compatible hardware" box.

snowdog · 23 Sep 2007 at 18:34

Didn't help, excact same list.

Anybody has any idea how to easely add knowlege to windows that there are more ACPI drivers?

Or, does anyone know where the ACPI driver is located in windows? I might try to force it to install the drivers from the files I'm using myself on my own pc?

I've never experienced this when swapping a 939 rig from Single to Dual Core but I've seen some people using this.

Maybe worth a try?

Works perfectly, finally my dad has a true dual core pc now

( and finally I can have 2 cores for supreme commander on his pc).

mattyrigby00 · 23 Sep 2007 at 19:02

glad to see it works now, i think that program just copys and pastes the files around to do it but its a lot easier doing it with that than moving files.

Camalot · 23 Sep 2007 at 19:33

Glad it's sorted mate
