multiprocessor not working anymore?

[robin1232]

ever since I upgraded to windows 7 (ultimate 64 bit) I had the idea one of my CPU's wasn't working, the same goes for my vista installation after that.
so now I ran "CPU identification utility" and it returned:

so now Im pretty sure it ain't working anymore.
so do you have any idea what could be causing this?

by the way, the type is core 2 duo E8200 of both and both the processors show up in device manager

CPU Identification Utility showed that you have 1 physical cpu with 2 cores. Are you saying you have 2 physical cpus? What make & model of motherboard?

how do I see that, I know the brand is foxconn, oh, wait, I have the box here... lets see... yep, foxconn G3IMX-K
the dual cpu did work in vista tough, but not anymore now (I rebooted in vista and ran some tests there, it returned the same)

foxconn G3IMX-K

If that is a multiprocessor board, where is the other cpu socket? You have 1 dual core cpu and the CPU identification utility is showing it correctly.

yeah, I could only see 1 socket in the manual too, but system requirements lab always displayed 2 processors (before I installed windows 7) rated at about 8 GHZ, now it says 1 processor rated at 4 GHZ

also, I was told at sale it had a quad core CPU

[robin1232]

okay, I found out the motherboard was in the wrong box, what I have is Foxconn G31MX

[Salmon Trout]

system requirements lab always displayed 2 processors

Some hardware information apps describe a dual core cpu as 2 cpus. System requirements lab is known to misreport when dual core cpu is fitted.

what I have is Foxconn G31MX

Still single cpu board

I was told at sale it had a quad core CPU

So you knew it was 1 cpu already. Anyway, you were told wrongly about the number of cores. I cannot say whether it was a mistake or a lie. E8200 is 2 core cpu.

That board supports multi-processer CPU's...what is the question ?, ?

The board supports a single cpu with multiple cores.

Here is an image of a true "multiprocessor" board with 2 cpus.



I suspect (although I am not sure!) that the OP was previously under the impression that he had a "multiprocessor" system and grew suspicious that one of them was not working when he noticed signs that there was only 1 physical cpu running.

Note how he says that the information from the CPU identification utility confirmed his suspicion that "one of his processors wasn't working" although that screendump shows a normal result for a dual core cpu.

but there are multiple processors running, it was always ranked higher on canyourunit.com
and device manager still says there are 2

A dual core CPU has 2 cores inside the package. They are identical and each one is a separate processor. A "multiprocessor" system has more than one CPU. Device manager on my P4 system shows 2 processors and there is only 1 cpu!

You have a single processor. It has two cores.

You have been told this about 4 times now.

Sorry....multi-core CPU's...
