Hi, I'm new to the forum, but this problem has been bugging me for a long time.
The issue does not lie with hyper-threading. I have a Dell Precision Workstation T7400 from 2007 with 1 Intel Xeon E5420 Quad Core clocked at 2.5 GHz, and I recently installed another Xeon E5420 with the same clock. That means 2 physical cores, 8 virtual cores.
Installation went pretty smoothly (apart from the extremely long screwdriver that I lacked for installation of the heat sink). When I booted the computer up and looked in the BIOS, voila! 2 physical cores, 8 virtual cores. I also looked into the device manager and it showed all 8 cores; however, when I open up task manager or any other program that identifies the amount of cores, I only get 4, which are the ones on the original CPU.
I've used task manager, CPU-Z from CPUID, and CPU Core Parking from Coderbag. All of them show only 4 cores. Is this merely a visual issue or is there actually something wrong?
I have provided an image link to show what I'm experiencing:

I use this as my primary desktop and also play a lot of games on it. I fear that if task manager or any other program doesn't detect all 8 cores, my games will not be able to utilize all 8 cores (more specifically, games that are even able to use 8 cores).
If anyone could enlighten me on this issue that I'm having, that would be greatly appreciated. Thanks!
