Duel core cpu maybe not being utilized in Vista according to Performance Graph?

[PM]

Hi all

Even though Duel core cpu is set in my bios and is listed under device
manager within Vista.
Yet when I check the performance manager, only one cpu is bening used.
i.e the graph in performance manager, only one cpu is shown.

Is there anywhere else in Vista I can check or a setting to change it?

My System is a Dell Dimesnion 9150 / XPS440
Vista Ultimate 64 bit
Intel cuel core, 3.2ghz
4gb ddram

Please reply to group or email

remove the (nospam)

TIA

On the performance page, select "One graph per CPU" on the View / CPU
History tab.
If you see two history graphs, then you're utilising both cpus even though
only one CPU usage graph is shown.

Hi mate and thanks for reply
I don't see two historyy graphs, only one and I cannot change it.
Vista Task Manager . Performance /
Under view cpu history, that option is greyed out and says one graph
per cpu
Could that mean Vista is not using both cpu's?

Just FYI -- I have a Core2 Duo. I checked my Windows Task Manager View/CPU
History/One Graph per CPU, and I do get two separate side-by-side graphs,
and the two traces show a different pattern, so I think I am seeing each of
the two CPUs. The caption for the graph display just says CPU Usage
History, and does not have a separate caption for each CPU. When I choose
View/CPU History/One Graph, all CPUs, there is just one long graph with one
trace, so I don't know which cpu is being traced.

Hi,
That is not what I get, I cannot choose between view one or two cpu's

Under system ( where the vista score is) what does your's say?

Mine says
Intel Pentium (R) D CPU 3.20GHz 3.19GHz

Yet under device manager it has.

Two Intel Pentium (R) D CPU 3.2GHz

I thought I should ad, processor is an Intel D core 940

This is nuts.

Intel own Processor ID program says I have 2 cores, yet windows
performance report says only 1
I reinstalled onto other HD my old XP Pro and sure enough dual cores
I've updated the BIOS, works great for Xp as I can turn on and off the
bios option to use both cores or not, but this doesn't effect Vsta at
all.

Well done MS
