I am working on a Dell Precision Workstation 470, running WinXP SP2. When I look in my Device Manager, it shows two Intel Xeon 3.20GHz CPUs. When I look in the Performance tab of the Task Manager, it shows me two real-time graphs in the CPU Usage History, and they aren't identical. When I go to Dell's website, and use the system profiler to tell me what's in my machine, it tells me I have two processors.
Well, I ordered the machine with only one processor, even though it's a dual processor motherboard. After all this weirdness, I opened up the case, and guess what? One processor. Next to it is an empty slot for a second one.
What is going on here?
