Lost Dual Core use but both show up - XP Pro SP3

I did a repair install and upgraded to SP3 but have noticed the system is
now only using one core of a dual core processor.

System hardware shows both, Everest shows both but a performance test shows
half usual performance and BIONC software is only running one core??

System in ASUS P5K-VM with Intel E6850 (Dual core)

Any suggestions,
M

Hi M,

Check that the BIOS is recognizing the 2 processors.

Get the latest drivers from Asus' webpage for your motherboard.

Take a look at Devide Manager, Processors, and check that both are working
without problems, try to update the drivers for them.

Also in the taskbar, check that you can assign processes like Bionic to a
specific processor, right buttom and Set Affinity... take a look if both
appear, and if its working, you got it.

Run Msconfig.exe and in Boot.ini tab, press advanced options and mark
NUMPROC and set it to 2.

Good luck!
Luis

Also, check that the env variable is set to number of proc=2

Right Clic My Computer/ Advanced/ Environment Variables NUMBER_OF_PROCESSORS
is set to 2.

Luis.
