Intel (R) Pentium(R) 4 CPU 3.40GHz (?dual core?)

[idata]

In my system management Windows XP Pro (My Computer-Manage-Device Manager-Processors) it lists TWO exactly the same 478 Pin units. I only upgraded with one CPU!! Why? Help please!

Also can you please direct me to any literature as I'm trying to work out how the post at "start-up" relates to the Spec. finder?

Thanks in Advance
