Only one core working

[Mick]

Have Asus P5VD1-X
Win xp Pro SP2 P805 Dual Core
7600GT
2x 512 MB PC 3200

Have lost Dual Core capablity, Used to see two graphs in task manager but
now only one.
Have updated ASUS Bios to latest 507 , all xp updates.
Bios sees two cores on startup.
2 processors seen in Device manager, which state they are working correctly.
Device shows ACPI multi processor.
Yet only one chart appears on Task Manager graph, function to see one chart
per CPU greyed out, and Premiere 2 only sees one processor.
have done full clean install of XP, deleted processors from device manager
and
redetected, no joy. only one still showing on task manager.
Sisoft sandra and CPUID and intell ID show no errors so where has my 2nd
core gone.
If i enable hyperthreading in bios( i know its not a hyperthread proc). Xp
Task manager shows two graph charts and premiere shows multi processor but
it crashes.
help.

Have you installed the chipset installation utility."Deleted from from device
mgr" ,you dont delete,you can uninstall or disable,but delete doesnt get you
anywhere...Also,try downloading the hyperthreading chk utility from
intel,thiers
also,processor identification utility,between the two you should get some
acurate results.

Hi,

In Windows Task Manager, click the view tab, in the dropdown menu, select
CPU History, select one graph per CPU.

Hope it helps.

No Joy. Task manager only has one chart showing. Option to show one chart
per CPU is greyed out
Bios shows two cores
Device manager shows two processors (working correctly??)
Intel ID shows one processor (one core)
Sisoft Sandra shows one processor (one core)
Premier 2 shows one processor

IS it motheroard or processor fault ??

Mick,
Try this, click Start, Run, then type "msconfig" in the run box, click "OK",
select the boot.ini tab, advanced options, check the box /NUMPROC= and set =
2, click "OK" and "OK" again to reboot/restart the computer, any change..?

you should activate hyperthreading in BIOS ( I´m using a D805 with no
HT but this is the only way I found to use both internals CPUs)

multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Microsoft Windows XP
Professional" /noexecute=optin /fastdetect /usepmtimer

Add "/usepmtimer" to the boot.ini file as in the sample above and reboot,
this can help fix irregularities on Intel and AMD dual-core systems.
I got the info from MAX PC's Dual-Core Survival Guide, June 2006 issue..
May help, your call..
