    P-State OC or Offset voltage no down-volting

    arnesaknussemm

      Hello there!

       

      I have a 1920X in an ASUS Zenith Extreme motherboard.

       

      I have tried BIOS 0804, 0902 and 0019

       

      The processor works flawlessly at stock and OCs manually flawlessly.

       

      However, if I set an offset voltage in BIOS or if I set a P-State OC the processor downclocks but does not downvolt.

       

      One or two eccentricities in the BIOS after BIOS flashback are making me wonder if the MB is at fault. But before I RMA it is it possible that the CPU is at fault?

       

      I have tried fresh OS installs on two different drives and made tested a whole range of power plans etc.

       

      Is it the CPU that requests downclocking and downvolting....or is it more likely to be a BIOS fault.

       

      Other TR owners have confirmed it is not a BIOS bug in general...they are able to see downvolting on offset and P-State setups. So it is something peculiar to my system.

       

      Thanks for any help!

          OK, so I have tried a new MB with no resolution to the issue...

           

          It is not offset per se, it seems to be changing multiplier or setting Multiplier with P-State OC that disables down-volting.

           

          An offset will allow down-volting with multiplier on auto. with boost enabled or disabled.

           

          If I set the multiplier and an offset I get down-clocking but no down-volting. Boost enabled or disabled.

           

          If I set a P-State OC I get down-clocking but no down-volting. Boost disabled. (Enabled N/A)
