    2600K & DP67BG Turbo Boost "Throttling"


      I wasn't sure if I should post this in the processors forum, or here.  But I believe it to be a problem with my board, so this forum is where I will post my problem.


      My Turbo Boost is being throttled.  I have my CPU set to boost to 4.5GHz in the BIOS (45 Multiplier - Base Clock remains at the stock 100).  Thing is, when I tax the processor to 100%, my clock only reaches 3.4 - 3.6 GHZ, never more.  The BIOS reports it to be 4.5GHz, like it should be.  But when in Windows, it never reaches that speed.


      I am running the latest BIOS version: BGP6710J.86A.2111.2011.1120.2157 (2111).  Unfortunately, I can't remember if this problem started when I updated to the latest BIOS, or before.  I didn't notice it until last night.  This problem hasn't always been.  I used to be able to reach 4.6GHz @ 1.25V (I'm one of the lucky ones when it comes to processor's).


      I've tried resetting all performance related settings to default values; using the (*cheat*) Automatic O/C settings in the BIOS, and so far have not been able to pinpoint what is causing this.  Any help would be appreciated.  Even guessing troubleshooting that I haven't though of would be appreciated.

      - 2x GTX 580 SLI

      - Sound Blaster X-Fi Titanium HD

      - W7 x64 Pro




      Immediately after posting this, I read the related posts, and it appears to be a problem with Intel's latest BIOS revision.  Intel fooked it.  So, I am going to roll back and see if it corrects the problem.  Other people have had success rolling back.
