General Software Discussion / RESOLVED: Intel Core 2 Duo + WinXP SP2 problem: only single core detected / used
« on: May 07, 2007, 03:19 PM »
I have bought new hardware, but am having great problems getting WinXP to use it correctly. I hope that one of DC's hardware gurus can shed some light on the problem...
Hardware
Mobo: Abit Il 9 Pro
CPU: Intel Core 2 Duo E6320
RAM: Corsair 2GB
HDs: 2 x Seagate Barracuda 7200 16MB 250GB
All bought as an upgrade kit from Komplett.co.uk
The Issue
WinXP SP2 doesn't detect / use the second core.
Issue verified by...
Test eith Other OSes
Ubuntu and Vista both find and use both cores... but I can't use either as my RT.x100 video editing card, does not have drivers for either.
I found a forum post (I forget where), which suggests that a dual core must have an ACPI version of the kernel HAL, and suggests that this can be forced during install of WinXP by hitting F5. This brings up a text menu of different HALs.
When I press F5, my menu only contains two items... Standard PC with C-Step i486 (which I know doesn't work) and Other.
Other prompts me to insert a floppy with drivers... I have neither a floppy drive nor any driver to give it!
I have also tried changing the computer type via the control panel, but again get no options other than StandardPC.
My WinXP cd is a slipstream of my original (which I no longer have) and includes SP2. I suppose it is possible that I have removed something from it which is removing support for dual cores... I have no idea what!
Any ideas??

The Issue
WinXP SP2 doesn't detect / use the second core.
Issue verified by...
- Only one CPU graph in Task Manager > Performance (one graph per CPU is checked)
- Generally slow performance.
- CPU-z reads correct CPU info, but cores drop down is greyed out and only shows core 1.
- Device Manager > Computer = StandardPC (I believe that dual core would read ACPI of some variety)
