    Core i7 860 not running at full speed.

    boing

      Hi guys, i have a core i7 processor that seems to be running way under speed on a gigabyte boeard and i was hoping for some advice on how to fix it.

       

      I'm running the following system

       

      CPU..........Core i7 860 (2.8Ghz)
      MB...........Gigabyte P55-UD4  bios F6
      Ram..........6Gb DDR3
      OS............Windows 7 64 bit

       

      when i checked easy tune (cpu utility) it says the clock is running at 2Ghz max (under load) dropping to 533 Mhz unloaded (should be 2.8Ghz). Now i know the processor has turbo mode and sleep modes but even under extreme multi threaded loading (3Ds Max rendering) with all cores at 100% it remains at 2Ghz.

       

      I checked the bios (not an expert before you ask any tricky questions....) here's what i found

       

      QPI frequency...............4798
      Uncore frequency..........2399
      Mem frequency.............1333

       

      turbo ratio...................15
      non turbo ratio.............15
      turbo frequency...........1999
      non turbo frequency......1999

       

      CPU clock ratio............15x
      CPU frequency.............2.0GHz

       

      Turbo boost................auto

       


      as i say i'm not an expert but  it seems that it is fundamentally set almost 1Ghz below where it should be. I was under the impression that modern boards set themselves, is there something i should have done when building it?

       


      I was advised on another board from a gigabyte user to reset CMOS and set the multiplier to 22 but i'm still a bit concerned that in the above numbers the turbo mode settings doon't differ from the standard ones, i don't want to start messing with bios settings that i don't fully understand.

       

      Is there a way to get this thing to auto configure or will i have to go through and do it all manually?

       

      Also if i do have to do it manually is a multiplier of 22 the norm for this CPU and what do i need to set the turbo ratio to?

       

      Any help is appreciated.
