    Flash to F3c beta bios. F1 still boot loops and can report overclocked failed, when loading some profiles or when changing certain settings (especially when going from a high to a low overclock), and f3c mostly prevents that, by usually doing a "soft" internal cycling instead of hard power cycling (which also helps it keep the bios settings). (The only time when f3c will boot loop uncontrollably (may require clear cmos) is if you try resuming from S3 with PLL overvoltage enabled, and it seems to automatically disable the PLL after an S3 resume=thus the chip can't boot if its beyond the multiplier wall.

    Confused about LLC...You sure you using LLC1? Did you clear the cmos before you installed the board? Because everyone who has used a B3 UD5 says that only LLC2 overvolts, and doesn't overvolt that much. Your LLC1 should have smaller vdroop, but should NOT overvolt.

    On the B2 boards, LLC1 with 1.55v would be over 1.60v under load, so I have NO idea where you got 1.408 from (and I didn't try the very last B2 beta bios, as that had PLL override removed)

    Use HWinfo32 to monitor your voltages on B3.

    B2 boards were overvolting a lot with LLC1.
