    i5 3570K overclock impossible

    poyoman39

      Hello, (and sorry for my english)

       

      I have installed recently a 3570K processor on my gigabyte Z68AP-D3 (rev 1.0) motherboard, but i can't modify the multiplier coefficient upper to 38x. (so i can't overclock it).

       

      i have installed the last version of the bios (F8), and my processor work corectly the rest of the time.

       

      Do you have an idea of what could cause this issue ?

          This could be caused by a limitation of the motherboard BIOS, since this processor us unlocked it should allow over-clocking.

          I would suggest contacting the motherboard manufacturer to see if the BIOS of your motherboard allow over-clocking the processor.

            yes, i 've already do this operation, but Gigabyte says it can't be due to their motherboard or bios version.

              In that case I would suggest running the Intel® Processor Identification Utility to determine if the processor is being properly recognized.

              You can download the Intel® Processor Identification Utility at:

              http://www.intel.com/support/processors/tools/piu/

               

              Also test the processor on another motherboard to see if it causes the same behavior.  If you do not have a spare motherboard to test with , perhaps you can test on a friend’s motherboard or by taking it to a local computer store.

                  Since the Intel® Processor Identification Utility is reporting the correct processor information, I would suggest testing the processor on another motherboard to see if it causes the same behavior, that is the easiest way to determine if the issue is causes by the processor or by the motherboard BIOS.

                      I am Also having this Issue on a GB Z68X-UD7-B3 in F10 Bios.

                      max OC is 3.8G, I have previously running a i5-2500K at 4.8G...

                        Apparently there is an incompatibility issue with 68X series MoBo's and Ivy CPU's... -.-
