Visa ultimate seeing two processors using only 1!

Hi,

I have just installed Vista Ultimate OEM on a Pentium D Dual core 3.4ghz
system.
Under device manager I have 2 processors, but task manager and all the other
diagnostic tools say I only have one processor using one core

I have tried everything to correct, can anyone help me please!!!!!

Under admin tools, there is a system config program. Under the boot tab,
there is an advance button. There is an option to set number of CPUs. If
everything is set normal, you might try setting it to 1 yourself and then
turning back off, or setting it to two.
 
There is nothing to correct - two things apply - BIOS must support the
processor (may not be the default) and applications must support dual core.
 
How can there be nothing to correct ? It's not working correctly or at
least, as expected. If Vista reports two processors then TaskManager at
least should show two processors. That's how it works for me. It would seem
odd, for the mobo not to support dual cores, yet Vista see them anyway. Of
course, in the taskmanger there is an option under View - CPU history that
says show one graph for all CPUs, which then makes it appear there is only 1
CPU.

Maybe what is confusing Vista is the Hyperthreading part. If the mobo
allowed it, I think I would try disabling HT and see if Vista is any happier
 
On My RC2 Vista Ultimate with dual cores it works exactly the same as it did
in XP.
1. Device Manager shows two processors.
2 Task Manger CPU performance normally shows the combined CPU perforamance
as if there is only one CPU.
3. If I go to Task manager/ processs and right click on a process for most
processes I have a CPU affinity option which is normally set to allow a
process to run on either CPU, however, if you have the option to run a
process on either CPU 1 or CPU2 then you know that both processors are
working properly.
 
Well, I'm not sure if we are talking 2 different things are not. But here is
what I've see from the 3 different versions I've installs, Enterprise, Hme
Prem and Ultimate. I got ot taskmanager and look at performance and see 2
CPU bars. This is how I see it in XP as well. I don't have a Dual core
Intel, the one I had was HT enabled and it also show the two CPU processes

I agree, if you have the option to set affinity and you have at least CPU 0
and CPU 1 that would sure seem to imply there are 2+ CPUs
