    i5 6400 cpu frequency low how fix ?

    SebastianCunha

      Since I'm sorry for my English because I'm using google translator, but it's the sequel my i5 6400 is with the very low frequency of 3.20 that would be normal it's only delivering 0.80, I've tried everything to revolve this problem, I uninstalled the driver Processor, updated drivers, updated bios of the motherboard, I changed the cpu ratio to 32x but even changing manually and the board applying the 32x the cpu continues delivering me only 8x of cpu ratio I do not know what to do I have this processor less than 6 Months and it's already giving me problems.

      In the attachments has a cpu-z image and a test done on the IntelProcessor Diagnostic Tool 64bit

          , Thank you very much for joining the Intel® Processors communities and for providing those files.

          According to the results of the Intel® processor diagnostics tool, the processor actually seems to be working fine:
          Processor Name: Intel(R) Core(TM) i5-6500 CPU @ 3.20GHz
          Expected CPU Frequency: 3.20
          Detected CPU Frequency: 3.19173
          Expected Base Clock: 100
          Detected Base Clock: 102.959

          Additionally, CPU-Z is a third party tool, and the readings or values showing on it might not be that accurate, besides the fact that it also does monitoring, maybe at the moment when you took the picture the PC was running at 800MHz, but that does not mean the processor is not capable of reaching 3.2MHz.

          Are you seeing some kind of problems with the PC, like getting freeze or random blue screens?

          Any further questions, please let me know.

          Regards,
          Alberto

            Thanks Intel for responding, I did the stress test using the Intel (R) Extreme Tuning Utility, and he pointed out only 800MHz also like the cpu-z that's leaving my computer extremely slow to the point of even watching videos on youtube is impossible.

              You are welcome. Thank you very much for letting us know those results.

              Since you mentioned the BIOS is up to date and so are the drivers the next thing to do in this case will be to swap parts. Do you have the option to test your processor on a different board or test your board with a different processor? This is in order to find out if the problem is related to the board or to the processor, that will be the best way to confirm the source of the problem. Remember that the Intel warranty is for 3 years, and if you do not have the option to try the steps above, we can always replace the processor for you, even though according to the test it is working fine. If you are interested in that option, please get in contact directly with Intel:

              Additionally, as a troubleshoot step, we can try to test the PC with minimal configuration, by using just one memory stick at the time on each slot, just to rule out a possible problem with any of the memory sticks or with the memory slots on the board, and the same thing with the hard drive/SSD, if you have the chance to test the PC with a different hard drive/SSD that will be very helpful to rule out a possible problem with it.

              Please let me know the results of trying the steps above.

              Any questions, please let me know.
