Does vista recognize multiple cores?

[Mausimo]

i recently got the ASUS M3A mobo with the AMD Phenom 9600 and 4 gigs of
ddr2 1066 crucial ballistix ram from a friend for a steal of a deal. It has
been used, but all working on a windows XP machine. He moved over to Intel
and installed all of this into another box for me, and i put vista on it.
However now, i am only seeing 1 cpu no matter what program i use(task
manager, cpuid, pcwizard, HWMonitor) and the ram is running at ddr2-800
(pc6400).

I updated the bios to beta version 0601, was running 0301(initial release).

If anyone has any ideas on how to fix this, it would be GREATLY appreciated

All editions of Vista can utilize one physical processor and however many
cores there are. The cores are seen as logical processors. A dual core cpu
will appear as one physical and two logical processors. A triple core as
one + three and a quad core as one + four.

If you are not seeing this then you should make sure that you have installed
any cpu driver needed for your board.

Vista Business and Ultimate can utilize two physical processors and all the
cores on each.

Have you tried the MultiMeter gadget?

"Hello "Mausimo":
I have a Core2 Duo using Vista Home Premium and an Intel Q6600 Quadcore
using Vista Ultimate and both show all cores in the processor. Vista seems
to do a nice job of spreading tasks across all the cores. Task Manager shows
a fairly even spread of CPU usage across all cores with occasional spikes on
one core that quickly evens out to all cores. I don't know why Task Manager
isn't showing all you cores but it may be due to the type of processor. AMD
quadcores natively control the memory I/O and maybe that fools the Task
manager into thinking there's only 1 core? Perhaps someone else with an AMD
Quadcore will post what Task manager shows with their CPU.

You might need the chipset drivers from Intel. Without the chipset
drivers, Vista has no clue. Go to www.intel.com and find the chipset
identification utility, then find your chipset drivers.

Thanks for all the responses, i tryed everything(all drivers) except the
chipset drivers. I had gotten so frustrated and PO'ed that i gave up and
re-formated and installed XP professional i had layin around.

All is working 100% - VISTA = Garbage YAY!
