How to activate all cores of i7 920

[Logan.M]

I come to realize through CPU-z only one core is active! I had doubts suites perf in 3dmark. By against I do not know how to activate them. Also I saw on the net people who put the screen of their device manager with actually 8 "processors" detected, not only me. By against I missing a device (well with one?).

What motherboard? Version of the bios? Give us a max info.

Apart from the drivers supplied with your motherboard, there is nothing else to do.

I have a ASUS P6T DeLuxe. I have bios version 0905 of 21/11/2008. What's funny is that in the bios I see my processor itself. For info, I have CPU-Z version 1.50 (which just supports the latest).

And in Windows with Ctrl - Alt - Delete, opening the task manager, how many cores appear in the "performance"?

1 - 2 - 4 - 8?

[Logan.M]

Just one. And yet I downloaded the utility cpu detection of Microsoft which detect the cpu well. In the BIOS, the CPU is present, but everything else (voltage etc) or is activated by default.

Please note that I am on Windows XP SP3. Need not necessarily pass under Vista anyway?

No, Vista is not necessary to use your i7.

Are you sure you installed all the drivers for the chipset and there is no conflict in device manager?

Otherwise, if by chance you have an "exotic" of Windows, it can explain the phenomenon.
