i7 920 only seeing one core

I recently purchased an i7 920 processor and am running it on an ASUS P6X58D Premium motherboard with the latest BIOS.

 

I am not able to see more than one core running.

The motherboard has the number of processor cores option set to Auto (the other choices are 1 and 2).

I've looed at msconfig -> boot-> advanced -> number of processors, but it only has 1 as an option.

Real Temp, CPUID all report one core.

The intel utility "Processor Identification Utility" reports 4 cores and no reported problems.

Does anyone have any ideas how I might go about determining if 4 cores are in fact running, and if not, how I might go about diagnosing the problem. I contacted both Intel and Asus technical support and they both point fingers at each other and recommend returning the others product for a replacement. I can do that, but it will take at 2 to 3 week turn around, and being without my main system that long isn't any fun.

Thanks in advance for your help.

download Cinebench R10 (google it) and run a test in on the Rendering (x CPU) and if u only get the score of around 4000+- or same as Rendering (1 CPU) it is faulty (this actualy happed to a mate of mine and it was faulty).

I was suffering the same problem.

For me the following steps (in VISTA) were the solution:

Goto msconfig:

General - selective start up - use original boot configuration (in dutch: "originele opstartconfiguratie")

After restart, all cores were visible at my computer in the task manager and in MSconfig.

If so then select manual all services and startup items.

I hope this will do.
