I don't understand why, but I only seem to have one processor working in Vista 5600 RC1 - System information shows two processors, but system info only shows one, as in the screenshot below. Task manager also only shows one processor activity window as well. Any ideas anyone? Anyone else having this problems?



System is:

Athlon 64 X2 4200+
1.5GB RAM
MSI K8N Platinum NForce 3 Ultra chipset....

One processer with two cores. Personally I don't have one, but I would think it SHOULD be displayed as one.

It should list 2 cores...


No idea? Sounds strange!
 
CPU-Z will of course detect the second core...but the problem is that Vista may not be.

Does it show 2 performance graphs in the CPU monitoring thingy?

ahh, so I was wrong.

Bizarre!

See, it includes the two processors in device manager, but there is only one ACPI Computer - I'm not sure if there should be two...
 
"Myth: Some versions of Windows Vista won't support dual-core CPUs or 64-bit processors.

Reality: Every Vista version supports dual-core processors, and every version is available in a 64-bit native version as well.

Part of the confusion rests with the specifications for some fairly exotic hardware. If you have a PC with multiple physical CPUs - that is, two or more chips installed on the motherboard - you'll need Windows Vista Business, Enterprise, or Ultimate to take advantage of both CPUs. If you install Vista Home Basic or Home Premium, the OS will only recognize one CPU. That's similar to the way Windows XP works today - if have a dual-CPU machine, you need to install XP Professional to use both CPUs.

So what about dual-core CPUs? That's different. All Vista versions, even the lowly Home Basic, support multiple cores on a single chip, with no additional configuration required.

The story with 64-bit Windows is a little more complicated. Today, Windows XP Professional is available in separate 32-bit and 64-bit versions that are functionally identical but must be purchased separately. In Vista, every version will be available in both 32- and 64-bit versions. A Microsoft spokesperson tells me they're still working out the details, but the current plan is to include 32-bit versions in retail packages; if you want to install a 64-bit version, you'll have to call and request that the alternative media be sent to you. The same spokesperson says Microsoft may include both 32-bit and 64-bit DVD media in the Windows Vista Ultimate box. For $399, that sounds like the right thing to do."

Well, this is Vista Ultimate - I don't think there's a single supported processor limitation.

Both CPUs working just fine under XP Professional...
 
Hmm. Running an X2 in the same build here. Mine doesn't specifically state multiprocessor like it does in XP, but it is registering as 2 cores in system info, and in task manager.

Is it me, or are 64 bit CPUs a big flop? MS should be pushing people to be using 64 bit, them not including a 64 bit OS in the box is doing no favours whatssoever

Beginning to agree with that. Certainly for now, 32 bit Vista is the way to go.
 
I thought when Longhorn first got announced, it was going to be purley 64 bit :confused:

oh well, maybe in the year 2010 when Blackcomb comes out

EDIT: nope im wrong, Blackcomb is going to have a 32 bit version out as well, its always good to see software being 5 years behind hardware :(
