Hello.
my problem is now i was using windows 7, then i checked for windows upgrade and it changed the windows into windows 10 automatically, from then The windows reads only 1 CPU from the 2, which already being read in the BIOS "as shown in the PICs"

So what should i do to make windows 10 read my 2 CPUs, BTW the windows version i use is " Windows 10 Pro "

Are there BIOS updates available for your MOTHERBOARD? Check and see if there are release notes indicating changes to multi-CPU OS support.

IKt might even be necessary to do a clean Install of Windows 10 in order for both Processors to be available.
Sometimes one is not seen if they are different steppings.
They are the same  ! :/Good to know motherboard make/model, CPU version and stepping, and BIOS version. Also answers to BC_Programmer's questions.

can u tell me how i got those info PLEASE !You can get more detailed info using some software, I like CPUID software.  CPUz & HWMonitor.  I've linked the downloads to the software names.

In addition, are you sure you are seeing only 1 CPU and not 2 CPU,s with hyper-threading disabled.

Please provide screenshots of all the tabs at once and post it.  Oh, and you can open CPUz SEVERAL times to achieve this.
