I have run hardinfo and generated a report and I am puzzled to see the processors. The report says that the computer has 4 i3 processors, but at the same time 3 of the 4 show to be running at 800 MHz ( atleast thats what I understand with the last column )
Intel(R) Core(TM) i3-2310M CPU @ 2.10GHz800.00MHz
Intel(R) Core(TM) i3-2310M CPU @ 2.10GHz2100.00MHz
Intel(R) Core(TM) i3-2310M CPU @ 2.10GHz800.00MHz
Intel(R) Core(TM) i3-2310M CPU @ 2.10GHz800.00MHz
I dont understand why do I have 800 MHz at 3 places? Can anyone answer?
Edit: Benchmark result

To me this seems quite normal. Intel speedstep regulates the clock-speeds and lowers them to save power. If you run a benchmark or something similar, you should see that the clock speeds are all 2100 MHz.

I agree with Daniel, there must be a mistake there anyway. I guess that one core is running on 800 MHz and one on 2100 MHz. This essentially means one is idle and one is not. If you install HWMonitor you can monitor the clock speed in realtime. This will help you see whether this is the constant state of your processor, or you only sometimes have this situation. If this gives you similar results, let us know. http://www.cpuid.com/softwares/hwmonitor.html. (what I meant before is to run a benchmark while measuring the clock-speed, as you can do for instance with HWMonitor)

1An i3-2310m has only two physical cores. It uses an intel technology called Hyper-threading. This essentially breaks up one core into two "virtual cores". This has some smart ideas that give you a performance advantage in some situations. Most computer programs don't see the difference between real physical cores and these virtual cores, therefore you see four cores, whereas you really have only two. – BramMooij – 2016-07-12T12:40:04.990
