Re: Dual Core issue

Here are two pictures of the problem I'm having.

Please help me to figure out why both cores aren't working or showing.
Thanks

Go to Device Manager and check the "Computer" entry. Under the (+)
sign, the HAL or Hardware Abstraction Layer will be listed. Mine
says "ACPI Multiprocessor PC". If yours says something different,
that might be part of the problem.

To change from ACPI Uniprocessor to ACPI Multiprocessor, you can
use the Driver Update option. This article gives the basic idea, but it
is for Win2K. WinXP should work the same way.

Note that some HAL changes are "difficult" and some are "easy". Changing
between ACPI Uniprocessor and ACPI Multiprocessor is "easy". If the
computer entry says "Standard PC", that is harder to escape from.

For a cross-check, that the hardware isn't doing this, you can
download a Linux distro like Knoppix, and burn a CD using the
ISO9660 you download. When booted, two penguin icons will appear
early in the boot sequence, indicating that a dual core was detected.
Other messages in the boot sequence (recorded in the dmesg for
later enjoyment), will also make mention of setting up the
multiple cores. That is what I mainly use the Linux LiveCD like
Knoppix for (knopper.net), is booting and testing hardware. If
an alternate OS also screws up, that is when you suspect a hardware
issue of some sort.

Sadly my device manager is only showing that entry once! How do I fix this? I
looked through my bios and there is no entry to change this. :(
I have no idea what I'm doing anymore. please help

Ben...my device manager is showing that same entry twice. One for each
core. I am sure you only have one enabled, thus only one graph in TM. You
might look thru your bios and see if there is an entry to change that.

Under Processors on device manager it shows AMD Athlon(tm) 64 x2 dual core
processor 3800+

Does it show both cores in device manager/processors? I have a dual

AMD WinXpMedia SP3, both show in task manager here.

the settings to see if the "show one graph per cpu" option
is on and thats not even an option. This has only changed
since I installed sp3. All of my programs seem to be
running slower, and I can't even run two programs at the
same time anymore. Any ideas on what I need to do to fix
this?

Wouldn't you need the 64bit version of it to run with
dual-core?

I'm running also a AMD dual-core but with another OS, and I
have both versions installed, the 32bit as well as the
64bit.

But if this happens with the 64bit I'm afraid I can't offer
you any solution except to wait and hope and wish for
updated fix or uninstall SP 3...
