I Have recently setup a new system with an AMD Athlon 64 bit Dual-Core processor on the Asus A8N-SLI motherboard, and I am running XP sp2. My system works fine apart from I cannot see both cores of the processor. Also, in device manager the'processor' list does not appear anywhere.
Using one of the AMD downloadable tools it is possible to see the activity of both cores, however this only shows the first (0)core. I also understand it is possible to select which processes to run on which core in task manager, I do not get the option to do this.
If anyone has an AMD dual core and knows a cure id be interested to hear, or if anyone knows what my problem may be.
