Title: Dual core cpu, only 1 showing up/working
Post by: Matt on May 23, 2016, 02:23:12 pm
While researching on my cpu I found out that it is a dual core, I checked msconfig, cpu-z and taskmanager and I only see one graph and the "one graph per cpu" is greyed out
msconfig and cpu-z also shows 1 core active
any solution for this?

You might be able to fix this by reinstalling the latest Intel chipset drivers and restarting your machine. Good starting point anyway!

Is your PC custom build, or manufacturer (OEM) built?

If it's custom built - you'll need the make and model of the motherboard.
If it's OEM built - you'll need the make and model (+ exact spec to search) of the PC.

Then you'll have to search the manufacturer's site for the chipset drivers. (Manufacturer will be either motherboard manufacturer, or OEM manufacturer of the PC).

my motherboard is BIOSTAR H61MGV3 7.0

TL;DR:

Download this driver and install it: http://download.biostar.com.tw/upload/Driver/Chipset/Intel/Infinst/Sandybridge/infinst.exe


No guarantees with this I'm afraid, but it's worth a shot!

Have you upgraded your CPU since the PC operating system (Windows 7) was installed?

It seems there is a tool and commands you can type in to fix this.

Stolen from the computing.net forum:

Get the tool here:

Read here:
http://www.ngohq.com/processors/11891-how-to-update-the-hal-without-reinstalling-windows.html

How to update from a single core APIC compatible CPU to a multi-core APIC compatible CPU

Under the computer entry in the device manager, you will see it says ACPI Uniprocessor PC, to update to the multiprocessor HAL input this:

devcon sethwid @ROOT\ACPI_HAL\0000 := +acpiapic_mp !acpiapic_up
devcon update c:\windows\inf\hal.inf acpiapic_mp.

Then reboot twice again to update the device and IRQ tables.

If the chipset update doesn't work (already mentioned in a previous post), then I'd try doing the above, or alternatively reinstall Windows as this will automatically detect the new processor!

We've all done stuff like that  :D

As the PC is booting up, keep tapping F8, and you should get to an "Advanced Boot Options" menu.
Use the arrows to select "Last known good configuration," and then click enter to select it. I believe that should fix the issue <3.

 :D about that... I never put a last good config  :D

That's okay  :D It should have automatically saved the last good configuration from your last successful boot.

Only took us just over an hour...  :rage:  :lol:

Vague process for those interested:
Chipset drivers updated (not too sure whether this was done or not as per recommendation  :lol:)
PC bluescreened due to invalid configuration in Windows boot file. (not too sure whether this was because the RAM had been set to 256MB, or whether it had been set to dual processor)
Created USB Windows installation media as system could not get to F8 Advanced Boot Options
Booted from USB, went to command prompt
Typed in these commands:
bcdedit /deletevalue {default} numproc  ---> Reset number of processors
bcdedit /deletevalue {default} truncatememory ---> Reset memory limit (removed it)
scf /scannow ---> Scans system files, checks if they're corrupted, attempts repair and local cache

System was then rebooted, went into Windows, and all 4 threads of the i3-2100 chip were visible in Windows.
