Hi everyone - Put my new system together and finally got a chance to run the Windows Experience Index. My concern is that the index shows the processor as having only 2 cores. This is an unlocked black edition A8 5600K. Did I fail to do something either within the BIOS or in Windows that keeps the other two cores "hidden"?  I really would love some assistance in this matter as I am not fully versed in this subject matter.

My system specs are as follows:

System

Manufacturer BIOSTAR Group Model Hi-Fi A85W Total amount of system memory 8.00 GB RAM System type       64-bit operating system   Display adapter type AMD Radeon HD 7560D Total available graphics memory 4076 MB Dedicated graphics memory 512 MB Dedicated system memory 0 MB Shared system memory 3564 MB Display adapter driver version 8.947.0.0 Primary monitor resolution 1920x1080 DirectX version DirectX 10

Update the BIOS or check cpu-z for better readings

Because technically it only has 2 cores, or two "bulldozer modules" made of one floating point and 2 integer units each. Depending on how you have your OS patched it will either report 2 or 4 cores.

Thanks for that suggestion. Updated BIOS but got same result. Updated drivers for GPU, got same results. Downloaded CPU-Z and checked overclock software that came with motherboard and found all 4 cores being utilized. Thanks for that reminder about CPU-Z. Used it years ago. Forgot all about it.
