Weird Device Manager Info
HI! I have this PC Sony PCV-RS510, Pentium 4 2.8 GHz, 512 MB DDR RAM, Integrated Video and Audio. I was checking out IRQs in the Device Manager and I noticed that the Processor is listed twice. I opened the Properties for each one of them and the iformation is exactly the same except for the Device Instance Id in the Details tab. The first Processor Device Instance Id is

And the second Processor Device Instance Id listed is

Also, when I looked in " Advanced System Information" in Control Panel, the same information shows as follow:

Processor: X86 Family 15 Model 2 Stepping 9 Genuine Intel 2793 MHz

Processor: X86 Family 15 Model 2 Stepping 9 Genuine Intel 2793 MHz

Why is the CPU showing up twice? It's not a Dual Core, so I don't understand the reason for that. I have almost the same kind of PC (Pentium 4 2.80 GHz...) and it is listed only once.

Hi,Digiboy! Thanks for your response! I now remember seeing the "HT" on the Intel logo when it boots up. That question was KILLING ME! So, it shows up as if it had a co-processor? Is that what it is? Thank you for your help!

Hyper-threading enables multi-threaded software applications to execute two software threads in parallel, thereby improving system responsiveness. Intel Pentium 4 Processors enabled with HT Technology deliver performance and multitasking gains that result in increased productivity and efficiency.
