  • x79-ud5 bios update

    hello to everyone
    i have a x79-ud5 motherboard with f13z bios
    the only problem that i have is that there is a vdrop under 100% load something that i didnt have with older bios
    do you guys think that with new f14b this problem will go away?
    do you think that i must do the update for any other reason?
    cpu i7 3930k
    mem gskill f3-17000cl9q-16gbzh

    thanks in advance

    Have you checked your advanced cpu core features? EIST and C1E will drop voltage when cpu is NOT under load.

      both are disabled ,the problem is that since f13p bios i had a stable vcore no matter cpu load and now with 100% cpu load i have vdrop about 30mv
      i know that this is normal but i was wandering if i can go back to a stable vcore no matter loads.
      i did the update and now i am running f14b bios and vdrop is still here
      thanks for your reply

        Try adjusting Load Line Calibration, not sure how your bios is laid out, it may be called something else. Other than that I can only think to flash back to previous bios.

            Somewhere on this forum is an article describing how to downgrade, I couldn't find it. Here is another article describing the procedure. Good luck!
