Not seeing both cores of my new Athlon X2 4200+

Morphware · Jan 14, 2006, 09:13 AM

First Hi to all, and hope someone can help me.

I have recently built myself a nice AMD Athlon X2 4200+ system but I can't see both cores active in the task manager. I have installed the driver off the AMD site and it lists in the device manager as the right driver (dated 10/26/2004 version 1.2.2.0)

I have already tried a clean install and I did see both cores functioning for a while, however they vanished again after a reboot.

Anyone can please point me in the right direction would be great.

Thanks.

hiyt CTL+ALT+Delete look at your task manager you should notice
two boxes fir CPU usage history under performance. as well as look
under set affnity in the right click menu of a process in your, process tab

Thats the problem I have no option to set driver affinity and I only have one processor histogram being displayed.

(Also look for a biosd update for your board)

My MB is using the latest bios available and it does support duel core processors, CPU-Z provides the following info:-

and the driver is :-

Crazy thing just happened, I went into the bios changed a memory setting and then booted back to xp and suddenly I had two cores. Restarted again and now I have only one again. It must be an outstanding issue with the bios, I hope MSI fix it soon because its got me kinda pissed at the moment.

Anyone else suffering from a similar problem? Does anyone know of a fix for it?

In "Hardware", is the Computer defined as an "ACPI Multiprocessor PC" ?

If you installed Windows before updating the BIOS, it may not have identified it correctly.

If your Windows install CD is not SP2, I'd suggest slipstreaming it before any re-install attempt.

Yes it is, I have found that by going into the bios whenever I reboot, saving and exiting it restarts with both cores, if I don't I only have access to one, must be a bios fault, am eagerly awaiting MSI to release a fix for it.
